ILTS School Psychologist (237) common mistakes
ILTS School Psychologist (237) · Understand the traps and how to avoid them.
Choosing an answer because it sounds like best practice in general, without checking whether the stem's data already rules it out (e.g., picking 'implement a behavior intervention plan' when the vignette shows the team has not yet completed a functional behavioral assessment).
Illinois licensure candidates often train on broad 'what should the school psychologist do' heuristics and answer from professional instinct rather than from the specific decision point the vignette creates. The exam frequently plants plausible next-step distractors that are correct in a different phase of the problem-solving sequence.
What to do instead
Before selecting, write down the phase of the problem-solving model the stem is in (referral, assessment, eligibility, intervention design, progress monitoring, reevaluation) and eliminate any option belonging to a later phase. Practice sorting answer choices by phase for 20 vignettes.
Treating the discrepancy between IQ and achievement as the required or primary method for identifying a specific learning disability, and rejecting response-to-intervention or pattern-of-strengths-and-weaknesses options because they seem less 'diagnostic'.
Many preparation materials and older field practice still frame SLD identification around ability-achievement discrepancy, while current Illinois and federal practice emphasize a process based on the child's response to scientific, research-based intervention and permit other research-based procedures. Candidates answer from outdated training.
What to do instead
Memorize the current regulatory language: a state must not require use of a severe discrepancy and must permit a process based on response to intervention. Drill 15 SLD eligibility items where the correct answer coordinates RTI data, exclusionary factors, and comprehensive evaluation rather than relying on a single IQ-achievement gap.
Confusing the three tiers of the state's multi-tiered framework and placing intensive, individualized, frequent-progress-monitoring support at Tier 2, or describing Tier 1 as something a student is 'placed into' rather than universal instruction for all.
Tier labels are used loosely in schools, and candidates conflate 'small group' with 'Tier 3'. The exam tests whether the candidate can match intensity, group size, and progress-monitoring frequency to the correct tier and can explain decision rules for movement between tiers.
What to do instead
Build a one-page table mapping tier to group size, instructional intensity, progress-monitoring frequency, and decision rules. Then answer 15 items that ask 'what tier does this scenario describe' and justify the match using the table.
Selecting an assessment instrument based on its reputation or the district's habit rather than on the referral question, the construct it measures, its norm group, and its technical adequacy for the specific student (e.g., using a norm-referenced cognitive battery as the primary tool to answer a question about classroom reading fluency).
Candidates memorize instrument names and subtests but not the decision logic that links referral question to construct to tool. Vignettes reward matching the measure to the question, and distractors are real, well-known instruments that measure the wrong thing.
What to do instead
For each major referral domain (reading, math, written expression, attention/behavior, autism, adaptive behavior, gifted, preschool), state the construct, the primary instrument type, and the technical evidence needed. Practice writing a one-sentence rationale for each instrument choice before looking at options.
Reading a standard score, percentile, or confidence interval as if it were a precise, fixed attribute of the child, and ignoring the standard error of measurement when comparing scores or deciding whether a difference is real.
Score interpretation is taught procedurally, so candidates can compute a score but freeze when asked what the interval means for decisions. Items test whether the candidate recognizes that observed scores are estimates and that small differences may be measurement error.
What to do instead
Practice converting standard scores to percentiles and confidence intervals by hand, then answer items asking whether two scores differ meaningfully given the SEM and whether a score falls in a classification range when the interval crosses a cutoff. State the rule: decisions use the interval, not the point estimate.
Naming a problem behavior or a diagnosis as the target of intervention instead of defining an observable, measurable, and operationally specified behavior, and skipping baseline data before recommending a plan.
Candidates know the vocabulary of behavior support but default to labels ('off-task', 'defiant', 'unmotivated') because labels are how referrals arrive. The exam tests operational definition and baseline logic, and distractors are label-based plans that sound compassionate.
What to do instead
Rewrite ten vague referral statements into observable definitions with topography, frequency, duration, and intensity. For each, specify what baseline data would be collected and how the intervention's success would be measured. Reject any answer option that targets a label rather than a behavior.
Skipping or minimizing informed consent and assent requirements - proceeding with evaluation, counseling, or release of records because a parent 'seemed fine with it' or because the team agreed informally.
Candidates focus on the technical content of practice and treat consent as paperwork. Exam items often present a sympathetic urgency (a student in crisis, a teacher demanding data) where the correct answer is to secure consent or follow the procedural safeguard.
What to do instead
Memorize the consent requirements for initial evaluation, reevaluation, counseling as a related service, and release of records, plus who may consent when parents are unavailable or rights are transferred. Drill items where the ethically attractive action conflicts with consent procedure, and always choose the option that preserves the safeguard while addressing the urgency.
Answering confidentiality items by disclosing information to whoever asks (a teacher, a principal, a probation officer) without applying the need-to-know standard, FERPA directory-information rules, or the limits of confidentiality explained at the outset of the relationship.
School psychologists work inside a building where information flows casually, and candidates import that norm into exam answers. Items test the boundary between legitimate educational interest and unauthorized disclosure, including subpoenas and safety exceptions.
What to do instead
Create a decision tree: who is asking, what is the purpose, is there a legitimate educational interest, is there a signed release, does a health-or-safety exception apply, is it a subpoena requiring legal review. Run 15 scenarios through the tree and note which exception, if any, applies.
Mismanaging time and item difficulty: spending many minutes on early scenario items, leaving later items unanswered, and changing correct answers on review without a specific reason.
The exam is long and scenario-heavy, and candidates who read every option twice on early items run out of pacing. Anxiety-driven answer changing also erodes scores when candidates second-guess well-reasoned responses.
What to do instead
Simulate full-length timed practice under exam conditions, set a per-item time budget, flag and move on from items exceeding it, and adopt a rule that an answer is changed only when a specific misread fact or rule is identified. Track flagged-item outcomes across two practice runs.
Answering consultation and family-engagement items by choosing the option that tells the teacher or parent what to do, rather than the option that builds shared problem definition, collaborative data collection, and consensual goal setting.
Candidates equate effective consultation with expert advice-giving and underestimate items that reward collaborative, consultee-centered process. Distractors are directive solutions that would likely fail in practice due to low buy-in.
What to do instead
Study the stages of collaborative consultation (entry, problem identification, problem analysis, plan implementation, evaluation) and practice selecting responses that ask, model, and jointly review data. For each consultation vignette, identify which stage the stem occupies before choosing.
