Mental Measurements Yearbook

In order for a test to be included in the latest edition of the MMY, it needs to be commercially available and to have been developed or substantially revised since the last edition was published. The publisher of the test also must provide adequate documentation describing the test's development and supporting the technical properties of the test. Each test published in the MMY is reviewed by at least one qualified doctoral-level professional. Most tests are reviewed by two reviewers. Reviews contain a description of the test, technical information, as well as information on the test's development and commentary on its strengths and weaknesses.

An online database containing information and all reviews of the more than 14,000 tests covered since the first edition is offered via electronic subscription from EBSCO Information Services and Ovid Technologies.
