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 Twelfth Mental Measurements Yearbook contains descriptions and reviews of over four hundred new or recently revised instruments in the English language.
