Mental Measurements Yearbook with Tests in Print This database is the result of merging two different but companion databases into one source. Mental Measurements Yearbook [MMY] contains descriptive information and critical reviews of over 2,000 commercially published tests in the English language. Tests in Print [TIP] serves as a comprehensive bibliography to all known commercially available tests that are currently in print in the English language. TIP provides vital information to users including test purpose, test publisher, in-print status, price, test acronym, intended test population, administration times, publication date(s), and test author(s). You can research current test information from TIP and continue the search to all available test reviews published in MMY.
