PSY-R6230 surveys the major categories of psychological tests, building the competency to select, describe, and critically evaluate the instruments psychologists use in clinical, educational, and forensic settings. The course provides breadth across the testing landscape rather than depth in any single instrument, establishing the foundation for the advanced assessment courses that follow.
Major psychological test categories

| Behavioral | Assess behavior through direct observation, rating scales, interviews | BASC-3, CBCL/Achenbach, Conners, Vineland-3 | Multi-informant assessment, halo effects, setting specificity |
What PSY-R6230 covers
Intelligence testing receives substantial attention because intelligence tests are the most frequently used individually administered psychological tests, central to special education eligibility decisions, and the most debated instruments in the field's history. The course covers the Wechsler scales (WAIS-IV for adults, WISC-V for children, WPPSI-IV for young children), the Stanford-Binet 5, and the Woodcock-Johnson IV Cognitive at the level needed to understand what each test measures, how its scores are structured (composite and index scores), and the CHC theory that underlies contemporary intelligence test organization. PSY-R6230 papers on intelligence testing must address both the instruments' psychometric strengths and the well-documented criticisms: cultural loading in item content, socioeconomic confounds in normative sampling, the gap between what IQ tests measure and the broader construct of "intelligence," and the historical misuse of intelligence testing for discriminatory purposes.
Personality assessment covers both objective (self-report questionnaire) and projective (ambiguous stimulus) methods. The MMPI-3 is the most widely used objective personality test in clinical and forensic settings; understanding its validity scales (which detect response styles including over-reporting, under-reporting, inconsistent responding, and non-responding), its restructured clinical scales, and its specific problems scales is essential clinical knowledge. The Rorschach Inkblot Test, now primarily administered using the Rorschach Performance Assessment System (R-PAS), has a more contested evidence base; PSY-R6230 papers should engage with both the supportive evidence (R-PAS has improved interrater reliability and normative data) and the criticisms (projective tests' incremental validity over self-report measures, examiner influence on responses).

Common writing assignments
Test review paper
Students select a specific psychological test and produce a comprehensive review covering: purpose and theoretical foundation, administration procedures, scoring and interpretation, psychometric properties (reliability, validity, normative sample), strengths and limitations, appropriate and inappropriate uses, and cultural/ethical considerations. The review applies the evaluation criteria from the Standards for Educational and Psychological Testing.
Assessment battery design
Students design a testing battery for a specific referral question (ADHD evaluation, learning disability assessment, personality evaluation for therapy planning, forensic competency evaluation), selecting instruments from different test categories, justifying each selection based on the referral question and client characteristics, and describing how the results from multiple tests will be integrated.
Test selection decision framework
- What is the referral question? Match the test to the question, not the other way around.
- Who is the client? Age, language, cultural background, disability status, reading level all constrain test selection.
- What are the psychometric properties? Reliability above .90 for individual decisions; valid for the intended use with this population.
- How current are the norms? Norms older than 15-20 years may not represent the current population (Flynn effect for IQ tests).
- What does this test add beyond other tests in the battery? Each test should provide incremental information.

Frequently asked questions
The Wechsler Adult Intelligence Scale, Fourth Edition (WAIS-IV) is the most widely used individually administered intelligence test for adults (ages 16-90). It produces a Full Scale IQ (FSIQ) and four index scores: Verbal Comprehension (vocabulary, general knowledge, abstract verbal reasoning), Perceptual Reasoning (visual-spatial processing, nonverbal reasoning, fluid intelligence), Working Memory (holding and manipulating information in short-term memory), and Processing Speed (rapid visual scanning and decision-making). The WAIS-IV uses a mean of 100 and standard deviation of 15 for composite scores. It is used for intellectual disability diagnosis (FSIQ below approximately 70 with concurrent adaptive behavior deficits), giftedness identification, neuropsychological evaluation, and forensic assessment. The WAIS-IV's normative sample included 2,200 adults stratified by age, sex, education, race/ethnicity, and geographic region to match the US Census.
The Minnesota Multiphasic Personality Inventory-3 (MMPI-3, published 2020) is the latest version of the most widely used objective personality test in clinical and forensic psychology. It contains 335 items (shorter than the MMPI-2's 567) and produces validity scales (detecting over-reporting, under-reporting, inconsistent responding), higher-order scales (Emotional/Internalizing Dysfunction, Thought Dysfunction, Behavioral/Externalizing Dysfunction), restructured clinical scales (replacing the original clinical scales that had high inter-scale correlation), specific problems scales, and interpersonal scales. Key improvements over the MMPI-2 include: updated normative sample, reduced item count, improved psychometric properties of all scales, removal of items with outdated or offensive content, and revision of the validity scales for better detection of specific response styles. The MMPI-3 is used for clinical diagnosis support, treatment planning, forensic evaluation (malingering detection, personal injury assessment), and personnel screening (law enforcement, security clearance).
Objective personality tests (MMPI-3, PAI, NEO-PI-R) use structured self-report questionnaires with fixed response options (true/false, Likert scales). They are called "objective" because the scoring is standardized and not dependent on examiner judgment. Their strengths include standardized administration, established reliability and validity, normative comparison, and built-in validity scales. Their limitations include susceptibility to response bias (social desirability, malingering) and dependence on the respondent's self-awareness and honesty. Projective personality tests (Rorschach, TAT, sentence completion) present ambiguous stimuli and ask the respondent to generate their own interpretation, theoretically revealing underlying personality dynamics, unconscious conflicts, and perceptual styles. Their strengths include less susceptibility to deliberate impression management (it is harder to fake when the "right answer" is unclear) and access to aspects of personality that the respondent may not be consciously aware of. Their limitations include lower inter-rater reliability (particularly for the TAT), contested validity for many scoring systems, examiner influence on responses, and the ongoing debate about whether projective tests add meaningful information beyond what objective tests and clinical interview provide.
Test battery selection begins with the referral question, not with favorite instruments. For an ADHD evaluation in a school-age child, the battery might include: a cognitive ability test (WISC-V, to rule out intellectual disability and identify processing speed/working memory weaknesses associated with ADHD), an achievement test (WIAT-4, to assess academic impact and rule out learning disabilities), behavior rating scales from multiple informants (Conners-4 from parent and teacher, to assess ADHD symptoms across settings), a continuous performance test (for sustained attention data), and clinical interview (developmental history, symptom timeline, functional impairment). Each instrument addresses a specific component of the referral question. The battery should be comprehensive enough to answer the referral question and conduct differential diagnosis, but not so long that it produces redundant data or exhausts the client. Each instrument must be psychometrically adequate for the specific client (appropriate age range, normative sample that represents the client's population, validated for the intended use).
