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 and critical reviews on the construction, use, and validity of commercially available tests published in English.

The objectives of the Mental Measurements Yearbooks have remained essentially the same since the start of the series. These objectives include provision to test users of

• factual information on all known tests published in the English-speaking countries of the world
• candidly critical test reviews written for the Mental Measurements Yearbook series by qualified professionals in education, psychology, speech/language/hearing, and other fields representing a variety of viewpoints
• unique publication of each volume in the Mental Measurements Yearbook series with new volumes supplementing rather than supplanting previous series volumes.

The importance of testing in our everyday lives has never been more vital or pronounced. Recognized worldwide as an essential resource on tests and testing, the Mental Measurements Yearbook series is an indispensable reference for anyone involved in the evaluation, selection, and use of commercially published assessments. The Twenty-First Mental Measurements Yearbook continues this long-standing tradition by providing professional reviews of more than 180 new or recently revised tests.

This addition to the Mental Measurements Yearbook series offers evaluations of the latest assessments in education, psychology, business, law, healthcare, counseling, and management. In addition to test reviews, descriptions of the purpose, target population, administration, scores, price, author, and publisher for each tests is provided. Reviews are written by highly qualified professionals with expertise in a range of disciplines. Test entries are cross-referenced and indexed by title, subject, name, acronym, and score. An updated directory of test publishers is also included.

The Buros Center for Testing, located in the Department of Educational Psychology at the University of Nebraska–Lincoln, continues the work of improving the science and practice of testing that Oscar Krisen Buros (1906–78) began in the 1930s.
