Assessment and Testing Flashcards

A school counselor administers a career interest inventory to a student in September and again in May. The student's results show a significant and unexpected shift in their top interest areas. This discrepancy raises the most concern about the inventory's:

Answer: test-retest reliability

Test-retest reliability refers to the consistency of a measure over time. If an assessment measuring a relatively stable trait, like career interests, yields vastly different results for the same person in a short period, it suggests the instrument is not reliable. Content validity relates to how well the test covers the subject, construct validity to whether it measures the intended underlying concept, and concurrent validity to how it correlates with other measures.

A client's score on a clinical assessment of anxiety is reported as a T-score of 70. How should the counselor interpret this score?

Answer: The score is two standard deviations above the mean, indicating a clinically significant level of anxiety.

T-scores are standardized scores with a mean of 50 and a standard deviation of 10. A score of 70 is 20 points, or two standard deviations, above the mean. On most clinical scales, a score this high is considered clinically significant and indicative of a problem or concern.

A counselor is asked to use an intelligence test that was standardized in the early 1990s on a predominantly suburban, middle-class population. The counselor's current clients are from a diverse, urban setting. Ethically, the counselor's primary concern should be the test's:

Answer: outdated and potentially culturally biased norms.

Using tests with outdated or inappropriate norms is a significant ethical concern. Norms provide the comparison group for a client's score, and if the norm group does not reflect the client's demographic (e.g., age, culture, socioeconomic status), the resulting interpretation is likely to be invalid and potentially harmful.

A high school counselor wants to help a student identify their potential for success in a skilled trade, such as automotive technology, which the student has not yet studied. Which of the following types of tests would be most appropriate for this purpose?

Answer: An aptitude test

Aptitude tests are designed to predict an individual's future performance or capacity to learn a new skill. In contrast, achievement tests measure knowledge and skills that have already been acquired. Since the student has not yet studied the subject, an aptitude test is the correct choice to assess their potential.

Which of the following best defines the Standard Error of Measurement (SEM)?

Answer: The degree to which a test score is likely to vary if the individual were to be re-tested multiple times.

The Standard Error of Measurement (SEM) is an index of the reliability of a test that estimates how an individual's score might fluctuate due to measurement error if they were to take the test repeatedly. It creates a confidence interval around the observed score, reflecting the score's precision.

A counselor designs a final exam for a graduate-level ethics course. The counselor meticulously ensures that the exam questions cover all major topic areas from the syllabus in proportion to the time spent on each topic during the semester. This process is primarily an effort to establish the exam's:

Answer: content validity

Content validity refers to the extent to which a test's items adequately represent the entire domain of the content it is designed to measure. By aligning exam questions with the course syllabus and topic coverage, the counselor is ensuring the test is a representative sample of the course material.
