Over 1,100 published tests including over 5,400 subtests, keyed to educational objectives of secondary education, were evaluated by measurement experts and educators. The tests were evaluated specifically with the concerns of grades nine and ten in mind. Upon a test's or subtest's assignment to one of the educational objectives, it was subjected to an intensive evaluation according to the MEAN system. MEAN is an acronym reflecting the four critical areas of concern to test users: Measurement Validity, Examinee Appropriateness, Administrative Usability, and Normed Technical Excellence. Thirteen of the 39 MEAN criteria deal with the empirical aspects of the test, mostly reliability and validity. Within any of the four evaluation categories, a letter grade, based on points assigned to each aspect of each criterion, was computed. Letter grades assigned were "G" (good), "F" (fair), and "P" (poor). Each test then earned four letter grades by the MEAN system serving as the Center's official evaluation of the test, for example: Acme Reading Test (GFPF). Along with the test evaluations which are presented in tabular form, an index of objectives, an index of tests evaluated, and a list of publishers and distributors of the tests are included. (RC)
