Praxis SLP 5331 common mistakes
Praxis SLP 5331 · Understand the traps and how to avoid them.
When an item asks about evidence-based practice, the candidate picks the answer that relies only on published research (e.g., 'use the treatment with the largest number of randomized controlled trials') and rejects answers that incorporate client and family preferences, values, or the clinician's own data-based judgment.
Candidates memorize EBP as a synonym for 'research evidence' and treat clinical expertise and client perspectives as optional add-ons rather than co-equal components.
What to do instead
Recite the three-part definition before every EBP item: best available external evidence + clinician expertise and client data + client/family values, preferences, and circumstances. If an option names only one leg of the stool, it is almost always the distractor; the correct answer integrates all three and the answer that appears 'unscientific' because it mentions preferences is often right.
The candidate selects an answer in which a speech-language pathology assistant (SLPA) independently administers and interprets a standardized assessment, diagnoses a disorder, writes initial goals, or signs off on a plan of care.
Candidates blur the line between 'assisting with' and 'performing' and assume that any task the SLP can do, an assistant can do with supervision.
What to do instead
Memorize the inviolable SLP-only list: evaluation and diagnosis, interpretation of test scores, development of the initial plan of care and goals, discharge decisions, and any task requiring clinical judgment. SLPAs may carry out prescribed treatment, collect data, and conduct screenings that the state permits, but the SLP retains interpretation and all decision-making; eliminate any option that lets the assistant interpret.
On legal and regulatory items, the candidate invents or misstates timelines and eligibility criteria, for example choosing that a student with passing grades is ineligible for services, that a child must 'fail' before being evaluated, or a wrong number of days between consent and the eligibility/IEP meeting.
Candidates memorize isolated numbers without anchoring them to the procedural framework, so under time pressure they guess between plausible-sounding day counts and infer eligibility from academic performance.
What to do instead
Hold the big guarantees first: child find, FAPE, least restrictive environment, parental consent, and procedural safeguards. Then attach the numbers to their steps (initial evaluation generally completed within 60 days of parental consent unless state rules are shorter; IEP developed within 30 days of the eligibility determination; re-evaluation at least every three years). Eligibility is driven by adverse educational impact, not report-card grades, and a 'wait to fail' or prerequisite-skills rationale is always wrong.
The candidate confuses sensitivity with specificity, or picks a screening instrument because it is described as 'highly accurate' overall, without asking which error (false positive versus false negative) the decision can tolerate.
The two terms are learned together and sound interchangeable, and candidates do not connect them to the purpose of the decision being made.
What to do instead
Attach a direction and a purpose to each: sensitivity is the true-positive rate, the proportion of people who have the disorder who test positive, so it is the property that rules a disorder out (few false negatives) and suits screening; specificity is the true-negative rate, the property that rules a disorder in (few false positives) and suits confirmation. Say the purpose out loud ('we are screening, so we want to miss nobody') before choosing.
The candidate scores a bilingual child's or a dialect-speaking child's performance on an English-only, norm-referenced test against monolingual norms, sees a low score, and selects 'language disorder' rather than 'language difference,' or selects an option that recommends immediate dismissal of all differences.
The score on the page looks objective and quantitative, and the candidate does not mentally substitute a comparison group or consider the child's language exposure history and dialect features.
What to do instead
Before answering, run two checks: (1) was the child compared with the right reference group, and (2) is the pattern atypical for the child's home language and dialect as well as English? Correct answers favor assessing in both languages, using interpreters, alternative and dynamic assessment, narrative and language-sample analysis, and distinguishing a difference from a disorder; a disorder is present only when the difficulty is evident in the child's total language system, not just in English.
The candidate interprets standard scores, percentile ranks, and score differences without reference to the normal curve or measurement error, for example concluding that a standard score of 85 is 'average,' that the 50th percentile means 50 percent correct, or that a five-point gap between two subtests is a real and meaningful discrepancy.
Candidates memorize isolated cutoff numbers without the distribution they sit in, and treat every score difference as if it were free of error.
What to do instead
Fix the anchors in memory: mean 100, standard deviation 15, so 85 = one standard deviation below the mean = about the 16th percentile and below average; 70 = two standard deviations below. Percentile rank is the percentage of the norm group scoring at or below that score, never percent correct. Before calling any difference meaningful, account for each test's standard error of measurement and confidence intervals and for whether the difference is statistically and clinically significant.
On aphasia items the candidate assigns the wrong syndrome, classically labeling Wernicke's aphasia as nonfluent because comprehension is poor, or misclassifying a fluent patient with good comprehension but impaired repetition (conduction aphasia) as anomic or Wernicke's.
Candidates try to hold six syndromes in working memory as a list of features instead of using two or three discriminating dimensions, so fluency gets attached to the wrong feature.
What to do instead
Recalibrate with a three-question decision grid applied in order: Is output fluent or nonfluent? Is comprehension intact or impaired? Is repetition intact or impaired? Then read the pattern: Broca (nonfluent, comprehension relatively spared, repetition impaired); Wernicke (fluent, comprehension impaired, repetition impaired); conduction (fluent, comprehension spared, repetition impaired); transcortical motor (nonfluent, repetition spared); transcortical sensory (fluent, comprehension impaired, repetition spared); anomic (fluent, comprehension and repetition spared, naming impaired).
The candidate chooses a treatment goal written as an aspiration rather than a behavior, such as 'Client will improve articulation skills' or 'Client will communicate more effectively,' or accepts a criterion so vague or so extreme (100 percent in all settings immediately) that it could not be measured or attained.
Goals learned in coursework are often copied as broad statements of intent, and the candidate responds to the goal's topic rather than auditing its structure for measurability.
What to do instead
Test every goal against three required parts: condition (given what materials, setting, or cueing), observable behavior (a countable or verifiable action such as 'produces /s/ in the initial position of words'), and criterion (accuracy level, across how many trials or sessions, with what level of cueing). If any of the three is missing, or the goal names an internal state like 'understand' or 'improve,' it is not the correct option.
The candidate applies the same treatment approach across ages, for example selecting direct confrontation and correction of every disfluency for a three-year-old who has just begun to stutter, or choosing to target /r/ in a four-year-old whose errors are developmentally appropriate.
Candidates pick the technique they associate most strongly with the disorder instead of filtering by the client's age, developmental norms, and time since onset.
What to do instead
Screen every treatment option through developmental expectation and risk first. For a preschool child with recent onset of stuttering, correct answers emphasize indirect approaches (parent counseling, slowing the communicative environment, reducing time pressure) with direct modification reserved for older children or persisting risk; for speech sounds, compare the error against the age of mastery norms before deciding it is a target at all.
For dysphagia items the candidate recommends the most protective or most restrictive option reflexively, such as NPO or thickened liquids for every patient with cough or a 'wet' voice, or the least restrictive option with no evidence for safety, and does not distinguish what can be concluded from a bedside examination versus an instrumental study.
Safety anxiety pushes the candidate toward the maximally cautious answer, and the candidate conflates a bedside screen (which can only flag risk) with instrumental assessment (which can characterize physiology and determine safe consistencies).
What to do instead
Anchor on two rules: recommend the least restrictive diet that is demonstrably safe, and let instrumental assessment (VFSS or FEES), not a bedside guess, determine which consistencies and postures are safe when aspiration risk is suspected. Know that thickened liquids are not risk-free (reduced hydration, residue) and that NPO is a temporary safety measure to be justified and revisited, not a default answer.
