CNSL 628 teaches counselors how to choose, use and explain assessment tools responsibly, from formal tests to interviews and rating scales.
UMGC describes it as an introduction to the principles and procedures of assessment in clinical professional counseling. Topics include psychometric concepts such as validity, reliability and norm- and criterion-referenced evaluation, good test construction, appraisal techniques, instrumentation, and communicating results.
The prerequisites are CNSL 614 and CNSL 624, which makes sense: the course combines research concepts with diagnostic purpose. Students usually find the psychometric vocabulary the steepest part.

What CNSL 628 Covers
- Psychometric concepts: validity, reliability, norms, norm- and criterion-referenced evaluation.
- Test construction and evaluation: what makes an instrument trustworthy.
- Formal instruments: the general classes of psychological measures and their characteristics.
- Informal assessment: observations, interviews and rating scales.
- Culture and age: effects on administration, scores and interpretation.
- Ethics and law in the testing process.
- Mental status evaluation and substance abuse assessment.
Key Concepts Explained
Reliability Versus Validity
Reliability is consistency: does the test give similar results under similar conditions? Validity is accuracy for a purpose: does it measure what it claims, for this use? A test can be reliable without being valid, but not the reverse.
Example: A bathroom scale that always reads 2 kg heavy is reliable (consistent) but not valid (inaccurate). A depression scale with high test-retest reliability still needs evidence that its scores relate to clinical depression, such as correlations with diagnostic interviews.
Norm- Versus Criterion-Referenced Scores
Norm-referenced scores compare a person with a reference group (percentiles, standard scores). Criterion-referenced scores compare performance with a fixed standard or cut-off.
Example: A T-score of 70 on a norm-referenced scale (mean 50, standard deviation 10) is two standard deviations above the mean, around the 98th percentile. A screening tool with a cut-off score is criterion-referenced: scores above the cut-off suggest further assessment, regardless of how others scored.
Fairness and Cultural Fit
Before using a test, check whether its norm group resembles your client and whether it has been studied in their language and culture. If not, interpret cautiously and say so in the report.
Communicating Results
The catalog highlights communication of results, and it is where many reports go wrong. Clients and other professionals need findings in plain language: what was measured, what the scores suggest, how confident you are, and what happens next.
A clear assessment summary avoids jargon, never relies on one score alone, combines formal results with interview and observation, and notes limits such as cultural fit or a client's fatigue during testing.
Typical Assignments and How to Approach Them
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Test review | Evaluating an instrument | Cover purpose, norms, reliability, validity, fairness and practical use |
| Score interpretation | Understanding scales | Convert to percentiles and explain meaning in plain words |
| Assessment report | Integrating sources ethically | Combine test results with interview data; note limitations |
| Ethics case | Legal and ethical testing duties | Address competence, consent, security and fair use |
Ethical and Legal Issues in Testing
The course covers ethical and legal issues in the testing process. In assignments these usually come down to a handful of duties that apply whatever instrument you use.
- Competence: use only instruments you are qualified to administer and interpret; some tests have user qualification levels.
- Informed consent: clients should know why they are being assessed and how results will be used.
- Test security: protect test materials and avoid sharing items or answer keys.
- Fair use: choose instruments appropriate to the client's language, culture, age and abilities.
- Confidentiality: store and release results only as law and consent allow.
Where Students Get Stuck
- Mixing up types of validity. Learn content, criterion-related and construct validity with one example each.
- Over-interpreting single scores. Use confidence intervals and multiple sources.
- Skipping the norm group. Who the test was standardized on matters as much as its reliability.
- Jargon in reports. Write for the client first.
Study Tips for CNSL 628
- Sketch a normal curve and mark standard scores, T-scores and percentiles until conversions are second nature.
- Use publisher manuals and independent test reviews as sources for test reviews, where your library provides them.
- Revisit your CNSL 614 notes on validity; many ideas carry over.
- Practice writing one-paragraph plain-language summaries of results.
