What is a standard score, and how is it interpreted in counseling assessments?

• A. A standard score is a transformed score with a fixed mean and standard deviation (e.g., mean 100, SD 15); it allows comparisons across tests.
• B. A standard score is the raw score before any transformation.
• C. A standard score is the maximum possible score on a test.
• D. A standard score indicates the test is invalid.

Answer: (C)

Standard scores are transformed scores that place performance on a common scale with a fixed mean and standard deviation (for example, mean 100 and SD 15). This standardization lets you compare results across different tests or subtests and interpret where a client stands relative to a normative group. In counseling assessments, you interpret by looking at how far above or below the mean the client is, in standard deviation units. With a mean of 100 and SD of 15, a score of 115 is one standard deviation above average, 85 is one standard deviation below, and 130 is two standard deviations above, and so on. This helps you communicate the client’s relative standing, identify strengths and areas for growth, and compare results across instruments. The standard score is not the raw score, not the test’s maximum possible score, and it doesn’t by itself indicate whether a test is valid.
