Posted 0 comments

modification/modified tests: A change in test content, format (including response formats), and/or administration conditions that is made to increase accessibility for some individuals but that also affects the construct measured and, consequently, results in scores that differ in meaning from scores from the unmodified assessment. test-retest coefficient/reliability: A reliability coefficient obtained by administering the same test a second time to the same group after a time interval and correlating the two sets of scores; typically used as a measure of stability of the test scores. benchmarking. item response theory (IRT): A mathematical model of the functional relationship between performance on a test item, the test item’s characteristics, and the test taker's standing on the construct being measured. See certification, credentialing. See local norms; norms. Twelve inches make up a foot. summative assessment: The assessment of a test taker’s knowledge and skills typically carried out at the completion of a program of learning, such as the end of an instructional unit.

Systematic collection, review, and use of information undertaken for the purpose of improving student learning (Palomba & Banta, 1999). Also called Cronbach's alpha and, for dichotomous items, KR 20. See cognitive assessment. See prompt. construct-irrelevant variance: Variance in test-taker scores that is attributable to extraneous factors that distort the meaning of the scores, and thereby, decrease the validity of the proposed interpretation. generalizability theory: Methodological framework for evaluating reliability/precision in which various sources error variance are estimated through the application of the statistical techniques of analysis of variance. It is usually measured in terms of inaccuracy and expressed as accuracy. interpreter: Someone who facilitates cross-cultural communication by converting concepts from one language to another (including sign language).

ERIC Digest. norm-referenced score interpretation: A score interpretation based on a comparison of a test taker's performance to the distribution of performance in a specified reference population. In contrast to test accommodations, test modifications change the construct being measured by the test to some extent and hence change score interpretations. discriminant evidence: Evidence indicating whether two tests interpreted as measures of different constructs are sufficiently independent (uncorrelated) to be considered two distinct constructs. from a larger specified set of possible entities, called the population. criterion domain: The construct domain of a variable that is used as a criterion. opportunity to learn: Whether test takers have been exposed to the tested constructs through their educational program and whether students have had exposure or experience with the language of instruction or the majority culture represented by the test.
