Question 1Assessment & Selection

In the federal hiring process, which document is primarily used to determine whether an applicant meets the minimum qualification requirements for a position?

  1. The agency's strategic plan
  2. The annual employee performance appraisal form
  3. The applicant's resume and supporting documentation submitted with the application Correct answer.
  4. The position's collective bargaining agreement

Explanation

Minimum qualifications are assessed against the information applicants submit in their application materials, such as a resume and supporting documents. These materials are compared to the qualification standard and job requirements for the position. Other agency documents do not describe an individual applicant's background.

Question 2Assessment & Selection

A hiring manager wants to fill a vacancy quickly while still considering a reasonable pool of candidates. Which practice best supports a valid, job-related selection decision?

  1. Choosing based on personal familiarity with the applicants
  2. Limiting review to applicants who share the manager's background
  3. Selecting the first applicant who applies
  4. Using predetermined job-related criteria applied consistently to all applicants Correct answer.

Explanation

Valid selection requires criteria that are job-related and applied consistently so that decisions reflect the requirements of the position. Consistent, predetermined criteria reduce bias and support defensibility. Personal familiarity or arbitrary shortcuts undermine fairness and merit system principles.

Question 3Assessment & Selection

Which principle is a core requirement of the federal merit system in hiring?

  1. Selection on the basis of relative ability, knowledge, and skills Correct answer.
  2. Selection based on nepotism
  3. Selection based on length of residence in the local area
  4. Selection based on political affiliation

Explanation

Merit system principles require selection and advancement based on relative ability, knowledge, and skills, with fair and open competition. Political affiliation, nepotism, and unrelated local factors are prohibited considerations. These principles protect the integrity of the selection process.

Question 4Assessment & Selection

An assessment used in hiring should be shown to be job-related. What does this primarily mean?

  1. The assessment measures knowledge, skills, or abilities that are important for successful performance in the job Correct answer.
  2. The assessment is popular with applicants
  3. The assessment can be completed without supervision
  4. The assessment is inexpensive to administer

Explanation

A job-related assessment measures constructs such as knowledge, skills, abilities, or other characteristics that matter for performance in the target job. Cost, popularity, and administration format are practical considerations but do not establish job relatedness. Job relatedness supports the validity and defensibility of selection decisions.

Question 5Assessment & Selection

What is the main purpose of a structured interview in a selection process?

  1. To standardize questions and scoring so candidates are compared on the same job-related criteria Correct answer.
  2. To shorten the interview to a few minutes
  3. To let each interviewer improvise questions based on personal interest
  4. To assess candidates primarily on personality similarity to the interviewer

Explanation

Structured interviews use predetermined, job-related questions and consistent scoring criteria for all candidates. Standardization improves reliability and comparability of ratings across candidates. Improvisation and similarity judgments reduce fairness and validity.

Question 6Assessment & Selection

Which action best reflects a merit-based, fair hiring decision when two applicants are similarly qualified?

  1. Selecting the applicant who applied last
  2. Selecting the applicant who lives closest to the office
  3. Selecting the applicant with the higher overall job-related assessment score Correct answer.
  4. Selecting the applicant who is a personal friend of the supervisor

Explanation

When applicants are similarly situated, the decision should still rest on job-related evidence such as assessment results. Personal relationships, application timing, and proximity are not valid job-related criteria. Merit-based decisions are grounded in relative ability and qualifications.

Question 7Assessment & Selection

A hiring panel wants to reduce the chance that an interviewer's first impression unfairly influences later ratings. Which practice best addresses this concern?

  1. Encouraging panel members to reach consensus before rating
  2. Allowing each panel member to change scores freely after discussion
  3. Having only one panel member rate all candidates
  4. Using a defined rating scale and recording evidence for each criterion before discussion Correct answer.

Explanation

Rating each criterion against a defined scale and documenting evidence before discussion helps limit first-impression and halo effects. Independent evidence-based ratings improve reliability. Free score changes and premature consensus can amplify bias rather than reduce it.

Question 8Assessment & Selection

Which statement best describes the relationship between reliability and validity in selection assessments?

  1. Validity guarantees perfect reliability
  2. Reliability is a necessary but not sufficient condition for validity Correct answer.
  3. An assessment can be valid without being reliable
  4. Reliability and validity are unrelated concepts

Explanation

Reliability refers to consistency of measurement, while validity refers to whether the assessment measures what it is intended to measure for the job. An assessment must be consistent to be meaningfully valid, but consistency alone does not establish validity. Thus reliability is necessary but not sufficient.

Question 9Assessment & Selection

An agency uses a written test that measures a skill required on the first day of the job. Which type of validity evidence is most directly supported by this design?

  1. Evidence based on test administration cost
  2. Evidence based on the number of test items
  3. Content-oriented evidence based on job-task linkage Correct answer.
  4. Evidence based on applicant satisfaction

Explanation

Content-oriented validity evidence comes from demonstrating that assessment content represents important job tasks or requirements. A test tied to a skill needed on the first day supports this linkage. Satisfaction, cost, and item count do not establish that the test reflects job content.

Question 10Assessment & Selection

A supervisor rates every employee as 'outstanding' regardless of performance. Which rating error does this illustrate?

  1. Central tendency
  2. Halo effect
  3. Contrast effect
  4. Leniency Correct answer.

Explanation

Leniency is the tendency to rate everyone favorably regardless of actual performance. Central tendency clusters ratings in the middle, and the halo effect lets one trait influence ratings on other traits. Contrast effect compares employees to one another rather than to a standard.

Question 11Assessment & Selection

Which of the following best describes a knowledge, skills, abilities, and other characteristics (KSAO) approach to job analysis?

  1. Identifying the worker attributes required to perform the job successfully Correct answer.
  2. Documenting the organizational chain of command
  3. Listing the tasks performed in the job only
  4. Recording the salary range for the position

Explanation

A KSAO approach focuses on the attributes a worker needs, such as knowledge, skills, abilities, and other characteristics, to perform the job well. Task lists describe what is done, not the attributes required. Salary and reporting relationships are not worker attributes.

Question 12Assessment & Selection

An assessment center uses multiple exercises and multiple trained assessors to evaluate candidates. What is the primary benefit of this design?

  1. It increases the number of candidates who can be tested at once
  2. It reduces the need for documented criteria
  3. It improves the reliability and breadth of behavioral observation Correct answer.
  4. It eliminates the need for job analysis

Explanation

Multiple exercises and assessors allow behavior to be observed across varied situations and reduce dependence on any single rater or task. This improves reliability and coverage of relevant competencies. Assessment centers still require job analysis and documented criteria.

Question 13Assessment & Selection

A candidate's score on a cognitive ability test is reported with a confidence interval. What does the interval primarily communicate?

  1. The percentage of job tasks the candidate can perform
  2. The exact true score of the candidate
  3. The candidate's rank among all applicants
  4. The range within which the candidate's true score is likely to fall, given measurement error Correct answer.

Explanation

A confidence interval reflects measurement error and expresses a range likely to contain the candidate's true score. It acknowledges that observed scores are not perfectly precise. It does not specify exact performance or ranking.

Question 14Assessment & Selection

Which practice best supports consistency when multiple raters evaluate candidates in a structured interview?

  1. Encouraging raters to discuss candidates before any independent scoring
  2. Rotating which criteria each rater scores without documentation
  3. Allowing each rater to define the rating scale independently
  4. Providing raters with behaviorally anchored rating scales and calibration training Correct answer.

Explanation

Behaviorally anchored scales and calibration training align raters on what each score level means, improving inter-rater reliability. Independent scale definitions and undocumented criteria introduce inconsistency. Discussion before independent scoring can bias ratings.

Question 15Assessment & Selection

An agency wants to verify that a selection procedure predicts job performance. Which approach provides criterion-related evidence?

  1. Reviewing whether test items look reasonable to subject matter experts
  2. Surveying applicants about their test experience
  3. Counting how many applicants completed the test
  4. Correlating assessment scores with later supervisory performance ratings Correct answer.

Explanation

Criterion-related validity evidence comes from the statistical relationship between assessment scores and a criterion such as job performance. Correlating scores with performance ratings directly tests that relationship. Expert review supports content evidence, and surveys or completion counts do not address prediction.

Question 16Assessment & Selection

Which action best reflects the principle of fair and open competition in a hiring announcement?

  1. Providing qualifications only after the closing date
  2. Restricting applications to people already known to the selecting official
  3. Posting the vacancy publicly with clear qualification requirements and application instructions Correct answer.
  4. Sharing the vacancy only within a small informal network

Explanation

Fair and open competition requires public notice of the vacancy with clear requirements and instructions so all interested qualified persons can apply. Closed or informal recruitment limits competition. Qualifications must be known in advance to allow fair application.

Question 17Assessment & Selection

A hiring team decides to use a work sample exercise. Which characteristic most supports the exercise's defensibility?

  1. The exercise closely mirrors important tasks identified through job analysis Correct answer.
  2. The exercise is completed without any scoring rubric
  3. The exercise is entertaining for candidates
  4. The exercise is unique and never used elsewhere

Explanation

A work sample is defensible when it represents important job tasks identified through job analysis and is scored against defined criteria. Entertainment value, novelty, and the absence of a rubric do not support defensibility. Job linkage is the central consideration.

Question 18Assessment & Selection

Which statement best describes adverse impact in selection?

  1. A delay in the hiring timeline
  2. A reduction in the number of applicants who apply
  3. A selection rate for one group that is substantially lower than the rate for another group Correct answer.
  4. Any selection decision that a candidate dislikes

Explanation

Adverse impact refers to a substantially lower selection rate for a protected group compared with another group. It concerns outcomes of the selection process rather than candidate preferences, applicant volume, or timing. When adverse impact appears, job relatedness and validity of the procedure become especially important.

Question 19Assessment & Selection

A test yields scores that are consistent across repeated administrations but do not predict performance on the job. What is the most accurate conclusion?

  1. The test is valid but unreliable
  2. The test is both reliable and valid
  3. The test is reliable but lacks criterion-related validity evidence Correct answer.
  4. The test has strong content validity

Explanation

Consistency across administrations indicates reliability, but the absence of a relationship with performance means criterion-related validity is not established. Reliability alone does not make a test useful for predicting job performance. Content validity would require separate evidence linking test content to job tasks.

Question 20Assessment & Selection

A selection panel uses a cut score on an assessment. Which consideration most directly supports setting a defensible cut score?

  1. Setting the cut score to produce a predetermined number of hires
  2. Setting the cut score at the median of the applicant pool
  3. Setting the cut score at the highest score achieved by any applicant
  4. Basing the cut score on the level of proficiency required for successful job performance Correct answer.

Explanation

A defensible cut score should reflect the level of proficiency needed for successful performance, ideally supported by job analysis and validity evidence. Pool medians, hiring targets, and top scores do not reflect job requirements. Cut scores tied to performance standards are more defensible.

Question 21Assessment & Selection

An agency finds that a selection procedure has adverse impact. Which response is most appropriate?

  1. Investigate whether the procedure is job-related and consistent with business necessity, and consider alternatives Correct answer.
  2. Lower standards for all applicants regardless of job requirements
  3. Discard all assessment procedures permanently
  4. Continue using the procedure without review

Explanation

When adverse impact is identified, the employer should examine whether the procedure is job-related and consistent with business necessity and whether equally effective alternatives with less impact exist. Simply continuing without review is indefensible, and abandoning all assessment ignores valid selection needs. Lowering standards without regard to job requirements undermines merit and validity.

Question 22Assessment & Selection

Which situation best illustrates the halo effect in a selection interview?

  1. A rater gives low scores to all candidates because the first candidate performed poorly
  2. A rater gives average scores to every candidate
  3. A rater scores each dimension independently using behavioral evidence
  4. A rater gives high scores on all dimensions because the candidate was well dressed Correct answer.

Explanation

The halo effect occurs when an impression on one characteristic, such as appearance, biases ratings on unrelated dimensions. Contrast effects involve comparing candidates to one another, and central tendency clusters scores near the middle. Independent evidence-based scoring reduces halo effects.

Question 23Assessment & Selection

What is the primary reason job analysis is considered foundational to a defensible selection system?

  1. It identifies the tasks and attributes that selection tools should measure Correct answer.
  2. It determines the salary of the position
  3. It replaces the need for any assessment
  4. It guarantees that all applicants will be hired

Explanation

Job analysis identifies the tasks and worker attributes important for performance, which in turn guides what selection tools should measure. This linkage supports job relatedness and validity. Job analysis does not guarantee hiring outcomes, replace assessments, or set salaries.

Question 24Assessment & Selection

A hiring manager wants to combine scores from two assessments into a single selection decision. Which approach best preserves the job-relatedness of the overall decision?

  1. Giving equal weight to both assessments regardless of their relevance
  2. Using only the assessment with the highest scores
  3. Weighting each assessment according to its importance for job performance Correct answer.
  4. Averaging scores without documenting the rationale

Explanation

Weighting assessments according to their importance for job performance keeps the combined decision aligned with job requirements. Equal weighting without regard to relevance, cherry-picking high scores, or undocumented averaging can distort the relationship to performance. Documenting the rationale supports defensibility.

Question 25Assessment & Selection

Which statement best describes the purpose of calibration among raters before a selection interview cycle?

  1. To select which candidates will be interviewed
  2. To ensure raters apply score levels consistently across candidates Correct answer.
  3. To replace the need for a scoring rubric
  4. To shorten the interview questions

Explanation

Calibration aligns raters on the meaning of score levels so that ratings are applied consistently across candidates. It does not determine who is interviewed, shorten questions, or replace a rubric. Consistency across raters supports reliable and fair comparisons.

Question 26Assessment & Selection

A selection specialist is asked to identify the first step in building a defensible hiring process. Which activity should come first?

  1. Training interviewers on behavioral questioning techniques
  2. Conducting a structured job analysis to define required work behaviors Correct answer.
  3. Purchasing a commercially published cognitive ability test
  4. Setting a passing score before any applicants are tested

Explanation

Selection content must be derived from documented job requirements, so a job analysis identifying tasks and required characteristics is the foundation for every later step. Tests, cut scores, and interviewer training are chosen or designed only after the job requirements are known.

Question 27Assessment & Selection

An agency administers the same structured interview to all candidates, but one interviewer consistently asks additional follow-up probes that others do not. Which threat to the assessment process does this create?

  1. Increased content validity of the interview
  2. Reduced standardization of the assessment procedure Correct answer.
  3. Stronger criterion-related validity evidence
  4. Improved inter-rater reliability across the panel

Explanation

Standardization requires that candidates be assessed under comparable conditions; differing probes mean candidates are not being evaluated on the same stimulus set. This variability lowers consistency and can introduce unfairness rather than improving validity or reliability.

Question 28Assessment & Selection

A selection battery combines a cognitive ability test and a conscientiousness measure. Scores on the two tests overlap substantially. Which psychometric property is being described?

  1. Test-retest reliability of the two measures
  2. Inter-rater reliability of the two measures
  3. Predictive validity of the two measures
  4. Discriminant validity between the two measures Correct answer.

Explanation

When two instruments intended to measure different constructs correlate strongly, they are not distinguishing between those constructs, which bears on discriminant validity. Reliability concerns consistency of measurement, and predictive validity concerns relationships with job performance criteria.

Question 29Assessment & Selection

An agency wants to reduce the reading demand of a written selection test that measures mechanical reasoning. Which adjustment best preserves what the test measures while reducing construct-irrelevant difficulty?

  1. Simplify sentence structure and vocabulary while keeping the reasoning items intact Correct answer.
  2. Replace the reasoning items with a reading comprehension passage
  3. Give candidates extra time only if they request it
  4. Remove the hardest reasoning items to shorten the test

Explanation

Construct-irrelevant variance arises when a test requires skills the job does not demand, such as advanced reading. Simplifying language while retaining the reasoning content keeps the measured construct intact and reduces the influence of unrelated reading ability.

Question 30Assessment & Selection

A supervisor must rate ten candidates on five separate competencies. To limit the tendency to let one strong competency color ratings on the others, which practice is most effective?

  1. Assign each candidate to a different rater
  2. Rate each candidate fully on all competencies before the next candidate
  3. Discuss candidates with one another before rating
  4. Rate all candidates on one competency before moving to the next competency Correct answer.

Explanation

Rating one dimension at a time across candidates reduces carryover from a salient dimension to the others, which is the mechanism behind halo effects. Rating a whole candidate at once encourages a global impression to drive all dimension ratings.

Question 31Assessment & Selection

An agency must choose between two finalists. The selecting official documents the specific job-related competencies compared, the evidence reviewed, and the rationale for the choice. Which principle does this documentation most directly support?

  1. Speed of the hiring process
  2. Confidentiality of candidate test scores
  3. Reduction of the applicant pool
  4. Transparency and accountability of the selection decision Correct answer.

Explanation

Recording the job-related basis for a selection decision makes the process reviewable and demonstrates that the choice was grounded in merit rather than preference. Such documentation supports accountability if the decision is later challenged.

Question 32Assessment & Selection

A personnel psychologist wants evidence that a new situational judgment test measures the same underlying construct as an established test of the same construct. Which evidence is most relevant?

  1. A low correlation with a measure of an unrelated construct
  2. A high correlation with the established test of the same construct Correct answer.
  3. A high internal consistency estimate for the new test
  4. A high correlation with supervisor ratings of performance

Explanation

Convergent evidence for construct validity is shown when a new measure correlates strongly with an established measure of the same construct. Internal consistency speaks to reliability, and correlations with unrelated constructs address discriminant rather than convergent evidence.

Question 33Assessment & Selection

An agency plans to use a physical ability test for a firefighter position. Which step best establishes that the test content is representative of job demands?

  1. Setting the passing score at the median of current employees
  2. Piloting the test on a small group of volunteers
  3. Linking each test event to physically demanding tasks documented in the job analysis Correct answer.
  4. Selecting test events that are easy to administer and score

Explanation

Content-oriented evidence requires a documented link between what the test requires and what the job requires. A job analysis that identifies the physically demanding tasks provides the basis for judging representativeness.

Question 34Assessment & Selection

A selection panel uses a behaviorally anchored rating scale for interviews. What is the primary advantage of anchoring scale points to specific examples of behavior?

  1. It clarifies what each rating level looks like, improving consistency among raters Correct answer.
  2. It removes the need to conduct a job analysis
  3. It guarantees the interview will have no adverse impact
  4. It eliminates the need for interviewer training

Explanation

Behavioral anchors describe concrete examples at each scale point, which gives raters a shared frame of reference and reduces idiosyncratic interpretation of the scale. Anchors support, but do not replace, training, job analysis, or adverse impact review.

Question 35Assessment & Selection

An agency finds that a written test screens out a much larger proportion of one protected group than another. Before deciding how to respond, which information is most important to gather?

  1. The average test score of the highest-scoring candidate
  2. Whether the test is job-related and consistent with business necessity Correct answer.
  3. The number of applicants who withdrew from the process
  4. The cost of administering the test

Explanation

When selection rates differ substantially across groups, the central question is whether the procedure is job-related and consistent with business necessity. That determination guides whether the procedure can be justified or must be revised or replaced.

Question 36Assessment & Selection

A hiring manager wants to ensure that a panel interview focuses on competencies that predict success in the target role. Which action should precede finalizing the interview questions?

  1. Review the resumes of the current applicant pool
  2. Ask each panel member to contribute their favorite questions
  3. Select questions that are quickest to score
  4. Review the job analysis to identify the critical competencies for the role Correct answer.

Explanation

Interview content should be derived from the competencies the job analysis identifies as critical so that questions target what actually drives performance. Personal favorites or administrative convenience are not defensible bases for content.

Question 37Assessment & Selection

Two raters independently score the same set of interview responses and their scores agree closely. Which property does this agreement most directly demonstrate?

  1. Content validity
  2. Test-retest reliability
  3. Inter-rater reliability Correct answer.
  4. Predictive validity

Explanation

Inter-rater reliability concerns the consistency of scores assigned by different raters to the same performances. Test-retest concerns stability over time, and validity concerns the meaning or predictive power of scores.

Question 38Assessment & Selection

An agency decides to use a minimum qualification screening step before administering a written assessment. Which outcome most directly results from this design choice?

  1. The assessment becomes automatically valid for predicting performance
  2. The agency no longer needs to monitor adverse impact
  3. The assessment is administered only to applicants who meet basic eligibility requirements Correct answer.
  4. The cut score on the assessment can be lowered without justification

Explanation

Minimum qualifications act as an eligibility filter, so only applicants meeting basic requirements proceed to later assessments. Screening does not by itself establish validity, justify arbitrary cut scores, or remove the obligation to monitor impact.

Question 39Assessment & Selection

A personnel researcher reports that a test's scores correlate .45 with later supervisory performance ratings. Which conclusion is best supported?

  1. The test has no relationship with job performance
  2. The test shows moderate criterion-related evidence for predicting job performance Correct answer.
  3. The test is unreliable and should be discarded
  4. The test measures the same construct as supervisory ratings

Explanation

A correlation of .45 indicates a moderate positive relationship between test scores and a performance criterion, which is criterion-related validity evidence. It does not establish perfect prediction or equivalence of constructs.

Question 40Assessment & Selection

An agency wants to combine scores from a structured interview and a work sample. Which practice best supports a defensible combined decision?

  1. Average the raw scores without regard to the scales used
  2. Weight each component according to its relevance to the job and its demonstrated relationship with performance Correct answer.
  3. Use whichever component gives the higher score for each candidate
  4. Give each component equal weight regardless of what it measures

Explanation

A defensible composite reflects the relative importance of the constructs and the evidence supporting each component. Arbitrary weighting, cherry-picking the higher score, or averaging incommensurable scales undermines the rationale for the decision.

Question 41Assessment & Selection

A selection specialist is asked to evaluate whether a proposed interview question about handling conflict is appropriate. Which criterion is most relevant?

  1. Whether the competency is identified in the job analysis as important for the role Correct answer.
  2. Whether the question is likely to elicit entertaining anecdotes
  3. Whether the question can be asked of all candidates in under two minutes
  4. Whether the question was used successfully by another agency

Explanation

Interview questions are defensible when they target competencies the job analysis shows are important to performance. Entertainment value, brevity, and prior use elsewhere are not evidence of job relatedness.

Question 42Assessment & Selection

An agency uses a panel of three assessors who each observe the same candidates in a role-play exercise. Which practice most improves the accuracy of the panel's judgments?

  1. Having assessors review candidates' resumes during the exercise
  2. Having assessors reach consensus before recording any observations
  3. Having the highest-ranking assessor set the ratings for the panel
  4. Having assessors record behavioral observations before discussing and rating Correct answer.

Explanation

Recording observable behaviors before discussion preserves independent evidence and reduces the influence of dominant panel members or premature consensus. Ratings grounded in documented behavior are more accurate than impression-based consensus.

Question 43Assessment & Selection

A manager argues that because a selection test is reliable, it must also be valid. Which response is most accurate?

  1. Validity is necessary but not sufficient for reliability
  2. Reliability and validity are unrelated properties
  3. A reliable test is valid by definition
  4. Reliability is necessary but not sufficient for validity Correct answer.

Explanation

A measure cannot be valid without being reliable, because inconsistent scores cannot consistently reflect the intended construct. However, consistent scores may still reflect something other than the intended construct, so reliability alone does not establish validity.

Question 44Assessment & Selection

An agency wants to estimate the consistency of scores on a selection test by splitting the items into two halves and correlating the half-scores. Which reliability estimate is being computed?

  1. Parallel-forms reliability
  2. Inter-rater reliability
  3. Split-half reliability Correct answer.
  4. Test-retest reliability

Explanation

Split-half reliability estimates internal consistency by correlating scores on two halves of the same test. Inter-rater reliability concerns agreement among raters, test-retest concerns stability over time, and parallel-forms concerns alternate versions.

Question 45Assessment & Selection

A selecting official has a strong impression that one candidate is a better cultural fit based on a shared hobby. The official wants to make a merit-based decision. Which action is most appropriate?

  1. Give the candidate extra credit for interpersonal compatibility
  2. Set aside the personal impression and evaluate documented job-related evidence for all candidates Correct answer.
  3. Ask the candidate to describe the shared hobby in detail
  4. Reduce the weight of the structured interview for this candidate

Explanation

Selection decisions must rest on documented, job-related evidence, and personal similarity is a common source of bias. Systematically evaluating all candidates against the same criteria protects the fairness of the decision.

Question 46Assessment & Selection

An agency is choosing between a general cognitive ability test and a job knowledge test for a technical role. Which consideration most directly bears on the choice?

  1. Which test is shorter to administer
  2. How closely each test's content maps to the tasks and requirements identified in the job analysis Correct answer.
  3. Which test is more familiar to the hiring panel
  4. Which test has the lower development cost

Explanation

The choice among assessments should be driven by how well each measures characteristics the job analysis shows are required. Administration time, cost, and familiarity are practical factors but do not establish job relatedness.

Question 47Assessment & Selection

A supervisor gives a candidate high ratings on every dimension after being impressed by the candidate's opening statement. Which phenomenon best explains this pattern?

  1. A central tendency error in rating
  2. A global impression influencing ratings on specific dimensions Correct answer.
  3. A leniency error applied to all candidates
  4. A contrast effect from the previous candidate

Explanation

When one salient impression drives ratings across separate dimensions, a global impression is spilling over into dimension-specific judgments. Central tendency concerns clustering near the middle, leniency concerns uniformly high ratings, and contrast concerns comparison with other candidates.

Question 48Assessment & Selection

An agency wants to confirm that a cut score on a selection test is defensible. Which evidence is most directly relevant?

  1. The number of candidates who would pass at each possible score
  2. The opinions of the selection panel about an appropriate standard
  3. A documented relationship between score levels and the ability to perform critical job tasks Correct answer.
  4. The average score of current employees in similar roles

Explanation

A cut score is defensible when it is anchored in evidence linking score levels to job performance or the ability to perform critical tasks. Pass rates, employee averages, and panel opinions do not by themselves establish the job-relatedness of the standard.

Question 49Assessment & Selection

An agency is preparing a structured interview and wants to reduce the chance that candidates are evaluated on differing criteria. Which design feature is most important?

  1. Allowing each interviewer to choose questions from a broad bank
  2. Varying rating criteria based on each candidate's background
  3. Using the same predetermined questions and rating criteria for every candidate Correct answer.
  4. Encouraging interviewers to follow interesting tangents

Explanation

Structured interviews standardize both the questions asked and the criteria used to evaluate responses, so differences in scores reflect candidates rather than interviewers. Flexible question banks, tangents, and individualized criteria all introduce inconsistency.

Question 50Assessment & Selection

A selection battery includes a test that produces very consistent scores but is only weakly related to job performance. Which conclusion is best supported?

  1. The test is both unreliable and invalid
  2. The test is valid but unreliable
  3. The test is reliable but provides limited evidence of criterion-related validity Correct answer.
  4. The test's reliability guarantees its usefulness for selection

Explanation

Consistency of scores reflects reliability, while the weak relationship with performance indicates limited criterion-related validity. A reliable measure can still fail to predict the criterion, which limits its usefulness for selection.
