The bulk of this document consists of reviews of over 60 criterion-referenced tests, most of which are used to test elementary or secondary-level achievement in the basic skills. For each test review, the following information is given: description of test, price, field test data, administration, scoring, and other comments. The tests are rated according to three categories of criteria: (1) conceptual validity--domain descriptions, agreement, and representativeness; (2) field test validity--sensitivity, item uniformity, divergent validity, lack of bias, and consistency of scores; and (3) appropriateness and usability--clarity of instructions, item review, visible characteristics, ease of responding, informativeness, curriculum cross-referencing, flexibility, alternate form availability, administration, scoring, recordkeeping, decision rules, and comparative or normative data. Guidelines on aspects of test selection are given: locating tests, comparing tests' technical and practical features, and comparing tests for their curricular relevance. Appendices list resources for developing or purchasing criterion-referenced tests, sources of other test reviews, definitions of terms, and available tests which were not reviewed. A subject index to the reviewed tests, a directory of publishers, and a sample of an exemplary domain description are also included. (GDC)
