The most widely acclaimed reference series in education and psychology, the Mental Measurements Yearbooks are designed to assist professionals in selecting and using standardized tests. The series, initiated in 1938, provides factual information, critical reviews, and comprehensive bibliographic references on the construction, use, and validity of all tests published in English. The objectives of the Mental Measurements Yearbooks have remained essentially the same since the publication of the series. These objectives include provision to test users of: factual information on all known tests published as separates in the English-speaking countries of the world candidly critical test reviews written for the MMY series by qualified professional people representing a variety of viewpoints unique publication of each volume in the MMY series with new volumes supplementing rather than supplanting previous series volumes. Each yearbook is a unique publication, supplementing rather than supplanting the previous volumes. The ninth edition of this widely acclaimed reference work is the most comprehensive yearbook to date. It includes 1,409 commercially published tests (19% more than in The Eighth Mental Measurements Yearbook), detailed descriptive information about each test, 1,266 original reviews (41% more than in The Eighth Mental Measurements Yearbook) prepared by 660 well-qualified professional reviewers, and extensive references on specific tests, including those selected by Buros Institute staff and those selected by reviewers. The tests are listed in alphabetical order for easy reference. The volume also features a state-of-the-art essay on "Mental Measurement: Some Emerging Trends" by Dr. Anne Anastasi, a leading figure in the field of measurement. Indexes to the volume are: an Index of Titles with cross references and identification of new and revised tests, an Index of Acronyms, a Classified Subject Index, a Publisher's Directory and Index which includes publisher names and addresses and test listings by publisher, and Index of Names, and an innovative Score Index which refers readers to tests featuring particular kinds of scores that are of interest to them.

The Ninth Mental Measurements Yearbook continues and extends this proud tradition of excellence in providing service to test users.
