While designing an entrance exam for an advanced counseling program, faculty set most items to a difficulty level where only 25% of applicants are expected to answer correctly. What is the intended outcome?
B. Select only the highest-performing candidates
A difficulty level of .25 means only 25% are expected to answer correctly, which is appropriate when the goal is to admit only top performers.
A counselor is designing a readiness test for children entering kindergarten. She decides to create items that increase in difficulty as the test progresses, so that later questions challenge higher-level skills. This design reflects which test format?
A. Spiral test
Spiral tests arrange items in order of increasing difficulty, which is appropriate for gauging ability across a range of skill levels.
In a normally distributed IQ test (mean = 100, SD = 15), which T-score corresponds to a raw score of 130?
A. 70
A raw 130 is 2 SD above mean; T-score formula (10z + 50) = 70.
After witnessing violence, a client experiences flashbacks for one month and hypervigilance. Appropriate provisional diagnosis:
A. Acute stress disorder
Duration under one month fits acute stress disorder; beyond one month → PTSD.
A counselor gives the same assessment to the same group twice over two weeks to check score stability. This is testing:
A. Test-retest reliability
Test-retest reliability checks consistency across repeated administrations.
Keeping a journal of irrational thoughts for therapy is best classified as: What is it classified as?

C. Shared only the minimum necessary information to achieve the educational purpose

In an assessment study, the correlation between two administrations of the same test, taken two weeks apart, is .42. Which conclusion is most appropriate?
B. The test’s stability over time is questionable
.42 is low for reliability; generally > .80 is considered acceptable.

An adolescent alternating between binge eating and purging through exercise demonstrates:

A counselor explains to a student intern that “psychometric” refers to: What?
B. Any form of mental testing or measurement
Psychometrics is the science of measuring mental functions and abilities through testing.
A researcher finds a correlation of 0.50 between two problem-solving ability tests. What percentage of the variance is explained by this correlation?
B. 25%
The percentage of variance explained is the square of the correlation coefficient (r = 0.50). Squaring 0.50 gives 0.25, or 25% of the variance is explained by the correlation. The remaining variance is 100% - 25% = 75%.
A client displays obsession with order, perfectionism, and control without intrusive unwanted thoughts. The diagnosis is:
B. OCPD

This pattern repeats for science and social studies. Which test format best describes this exam?
B. Cyclical test
A cyclical test contains multiple sections, each section organized like a spiral (from easy to difficult), but difficulty resets at the start of each new section.
One advantage of interest inventories is that they: What is an advantage?
C. Are generally reliable and non-threatening

A. Reliable but not valid
Reliability means consistency; validity means accuracy. A test can be consistent but still inaccurate.
A counselor avoids relying solely on self-report questionnaires because: Why?
A. Clients often give inaccurate answers
Self-reports can be influenced by bias or inaccurate self-perception.
In a predictive validity study, the correlation between high school GPA and first-year college GPA is found to be .48. Which of the following is the most accurate interpretation?
B. 23% of the variance in college GPA is accounted for by high school GPA
(.48)² = .2304 → ~23% shared variance
