7.5 Assessment Referral, Selection, Interpretation, and Planning
Key Takeaways
- Define the decision and referral question before selecting an instrument; testing without a decision purpose creates data without direction.
- Use multiple methods and sources, including client report, records, observation, situational evidence, and appropriate standardized measures.
- Select and interpret instruments with attention to validity, reliability, norms, language, culture, disability access, and the effect of accommodations.
- Reports should state sources and limitations, translate results into functional meaning, and connect recommendations to the client's goals and environment.
7.5 Assessment Referral, Selection, Interpretation, and Planning
Begin With the Decision
Assessment is a problem-solving process, not a stack of tests. Define who is asking, what decision must be made, what the client wants, and how results may be used. Referral questions might concern vocational interests, transferable skills, learning needs, cognitive access, work tolerance, accommodation, treatment planning, or readiness for a specific training demand. “Complete a vocational evaluation” is a service request; “identify training options consistent with current reading skills, interests, stamina, and local opportunity” is a decision-focused question.
Explain purpose, procedures, foreseeable risks, recipients, confidentiality limits, fees, and the client's ability to ask questions. In a third-party evaluation, clarify the evaluator's role and that the report may go to the retaining party. Review records and existing results before retesting. Obtain releases or another valid basis for collateral information.
Formal and Informal Methods
Formal assessment uses standardized administration and scoring, with evidence regarding reliability, validity, and norms. It can support comparisons and quantify specific constructs. Informal assessment includes interview, behavioral observation, checklists, work-history analysis, portfolio review, situational tasks, job tryout, and ecological observation. Informal does not mean careless; methods, conditions, criteria, and limitations should be documented.
A multimethod approach reduces the weakness of any single source. Self-report provides meaning and experience; records provide history; tests sample defined constructs; observation shows behavior under particular conditions; and real or simulated work reveals person–task interaction. Discrepancies are information. A high mechanical aptitude score and poor shop performance might prompt examination of instruction format, anxiety, fatigue, safety procedures, or whether the test's demands match the actual task.
Selecting Measures
An instrument must fit the referral question and the examinee. Examine construct definition, population, norm recency and representation, reliability for the intended decision, validity evidence, reading and language demand, administration time, accessibility, cost, and required qualifications. A technically strong test can still be inappropriate when its norms exclude the relevant population or when vision, motor, hearing, language, or cognitive demands contaminate the target construct.
Provide reasonable access while protecting score meaning. Some accommodations—accessible display, breaks, assistive input, interpreter, extended time—may alter standardization depending on the test and construct. Consult the manual or publisher and document the modification. Do not automatically withhold access or automatically report a standard score whose comparability is no longer supported. Sometimes a qualitative interpretation or alternative measure is more defensible.
Refer to a psychologist, physician, occupational therapist, speech-language pathologist, benefits specialist, or other professional when the question exceeds the counselor's competence or legal scope. A good referral states the question and relevant context without directing a predetermined conclusion.
Administration and Interpretation
Prepare an accessible environment and verify understanding of instructions. Record deviations, behavior, fatigue, pain, assistive technology, interruptions, motivation, rapport, and language factors that may affect results. Interpretation begins with whether the administration supports the proposed inference.
Use confidence intervals and converging evidence rather than treating a score as exact. Percentile rank is not percent correct; grade equivalent is not a placement recommendation; correlation does not prove cause. Compare results only where the norms and scales support comparison. Consider base rates and avoid making a diagnosis from one instrument.
Translate scores into functional hypotheses. Rather than “processing speed is low,” explain that the observed pattern may affect rapid visual scanning under time pressure and should be compared with actual job pace, accuracy, and possible supports. State alternative explanations and the limits of prediction.
Feedback and Planning
Feedback is part of assessment. Present results in accessible language, invite the client's interpretation, correct misunderstandings, and discuss disagreement. Highlight strengths and context, not only deficits. The client should understand what was measured, what was not, how confident the conclusions are, and how information will influence options.
Recommendations must be specific and linked to evidence. “Needs job coaching” is incomplete. Describe the target skill, setting, expected intensity, progress measure, and review point. Integrate interests, values, labor-market realities, health, transportation, benefits, culture, and informed choice. Where findings are uncertain, recommend a situational assessment or trial rather than closing an option categorically.
Protect protocols and copyrighted test material, store records securely, and release reports according to consent, law, contract, and the Code. Document source dates because old results may no longer represent current function. The final product is not a score profile; it is a transparent answer to the referral question that improves collaborative planning.
Assessment Decision Table
| Decision point | Required question |
|---|---|
| Purpose | What decision will the information support? |
| Method | Which formal and informal sources best answer it? |
| Access | Will language, disability, culture, or modification affect administration or inference? |
| Interpretation | Do reliability, validity, norms, conditions, and converging evidence support the conclusion? |
| Action | How will the finding change a client-valued plan, and how will it be validated? |
If a method cannot improve the decision, reconsider whether it is necessary.
