The details presented in technical manuals for tests generally address a common core of issues related to the psychometric quality of the tests and the interpretation of their results. In this article, major categories of technical information are described in practical terms and related to test use and interpretation: (a) logical evidence of validity, (b) empirical evidence of validity, (c) types of reliability estimates for evaluating and interpreting tests, and (d) practical issues in understanding standardization data and using norms. The article is organized as a series of 20 questions concerning these categories of information. Responses to the questions include discussions of key measurement concepts and examples of the kinds of tests used by speech-language pathologists. Potentially unfamiliar or confusing terms are italicized when first used, and each term is followed by a brief definition.
