CAET common mistakes
CAET · Understand the traps and how to avoid them.
Treating the CAET as a pure recall test and memorizing lists of facts (e.g., muscle actions, nerve roots) without practicing application to a described patient scenario, so that scenario-based items about a specific amputation level or residual limb are answered by matching a keyword to a memorized fact rather than reasoning through the case.
Candidates transfer study habits from fact-dense coursework and assume volume of memorized content is the main predictor of success; the exam instead tests application and clinical judgment, so isolated facts are insufficient.
What to do instead
Convert every fact into a 'so what' question: for each fact you review, write one short patient vignette in which that fact changes a decision, and practice answering it before checking the source. Track the proportion of your practice that is scenario-based rather than flashcard-based.
Selecting the first plausible answer option and moving on without reading all options, so that a 'best answer' item is missed because a later option is more complete or more appropriate for the specific patient described.
Time pressure and the familiarity of one option create a confirmation bias; the candidate stops evaluating once an option feels correct.
What to do instead
Adopt a fixed routine: read the stem, predict the answer before looking, read every option, then explicitly state why each rejected option is wrong. Practice with timed sets but score yourself on whether you eliminated all distractors, not only on whether you chose correctly.
Ignoring the specific qualifiers in item stems (age, time since injury, acuity, weight-bearing status, cognitive status, setting) and answering a generic version of the question rather than the one asked.
Under time pressure candidates pattern-match on the topic keyword and skip the modifiers that determine the correct answer, especially in items where two options are both defensible in general but only one fits the stated conditions.
What to do instead
Before answering, underline or mentally list every qualifier in the stem and ask which option is invalidated by each one. Build practice sets specifically composed of paired items that differ only by a single qualifier so the effect of that qualifier becomes salient.
Confusing the sequence of assessment and intervention, or the sequence of a device-fitting process, answering with a later step when the question asks for the next or first action.
Knowledge of the individual steps is present but the ordering logic is not consolidated, and stems that ask for 'next' or 'initial' are read as 'what is important here'.
What to do instead
For each major process (evaluation sequence, prosthetic/orthotic fitting, wound or residual limb management, functional training progression), write the ordered steps from memory, then verify against a source and annotate the clinical reason each step precedes the next. Drill 'next step' and 'first step' items separately.
Applying textbook norms to a patient whose presentation contradicts them (e.g., recommending an aggressive protocol for a patient with poor skin integrity, cognitive impairment, or limited support) instead of adjusting the plan to the described constraints.
Candidates memorize standard protocols as fixed rules and have not practiced modifying them under real-world constraints, which the exam deliberately tests.
What to do instead
For each standard intervention you review, write down at least two contraindications or modifying factors and how the plan changes. Practice items that pair a standard protocol with a complicating patient factor and require you to justify the modification.
Answering prosthetic and orthotic items on the basis of device name or appearance rather than matching device components and design features to the patient's functional level, residual limb characteristics, and goals.
Device terminology is dense and easily memorized as labels; candidates learn what a device is called without learning the clinical criteria that determine when it is indicated.
What to do instead
Build a comparison table for each device category with columns for indication, contraindication, functional level required, and key component trade-offs, and populate it from clinical reasoning rather than definitions. Then answer items by first classifying the patient's functional level and constraints, and only then selecting the device.
Choosing an answer that reflects what the clinician thinks is clinically ideal while ignoring the patient's stated values, consent, autonomy, or the ethical hierarchy when these conflict, or conversely defaulting to patient preference when the item tests a safety or scope-of-practice obligation.
Candidates conflate 'best clinical outcome' with 'best answer' and have not practiced distinguishing ethical principles or resolving conflicts between them in concrete scenarios.
What to do instead
For ethics and safety items, identify which principle or obligation the stem is actually testing (autonomy, beneficence, nonmaleficence, justice, scope of practice, informed consent, mandatory reporting) before evaluating options. Practice with paired items where the clinically optimal and ethically correct answers diverge.
Overgeneralizing from a single study or treating any published finding as established evidence, without attending to study design, sample size, or level of evidence when the item asks how findings should be interpreted or applied.
Candidates have limited exposure to critical appraisal and default to 'research says X, therefore X is true', which the exam exploits with items containing weak or inapplicable evidence.
What to do instead
Practice appraising short abstract-style summaries for design, sample, generalizability, and confounders before answering. Memorize a simple hierarchy of evidence and apply it explicitly: state the level of evidence in the stem and let it constrain how strongly you endorse the finding.
Misreading the communication scenario by answering as the clinician's internal reasoning rather than choosing the response that actually demonstrates the target communication behavior (e.g., open-ended question, reflective listening, teach-back, addressing the patient's concern before providing information).
Candidates answer with the content they would want to convey rather than the process skill being tested, and they have not practiced distinguishing responses that inform from responses that elicit or confirm understanding.
What to do instead
Label each communication item with the specific skill it targets before choosing, and eliminate options that are clinician-centered, premature advice-giving, or closed-ended when the target is exploration. Practice writing the ideal response yourself and comparing it with the options.
Managing time poorly: spending excessive time on difficult items early, leaving later items unanswered or rushed, and failing to use remaining time to review flagged items and check for misread stems or transcription errors.
Perfectionism on early items plus anxiety about the stakes leads to a front-loaded pace, and candidates do not rehearse pacing under exam-like conditions.
What to do instead
Practice full-length timed sets with a fixed per-item budget and a rule to flag and move on after the budget is exceeded. Reserve the final minutes for a review pass focused on flagged items and on re-reading stems of answered items for qualifiers and negation.
