The publisher proposes to supplement the Mental Measurements Yearbook by publishing periodic surveys to tests not available commercially. Based on the 1970 issues of 29 journals, its orientation is predominantly educational, but includes material related to psychology, sociology, and personnel work. Mental measures are organized under 22 categories: achievement, adjustment (educational), adjustment (psychological), adjustment (social), aptitude, attitudes, communication, concept meaning, creativity, development, family, institutional information, interest, motivation, personality, perception, preference, problem-solving, status, trait measurement, values and vocational evaluation. Any of the following facts available are listed for each measure: test name, purpose, description (number of items, time required, format), statistics (reliability and validity), source (author and journal title in which the test was mentioned), and related research.
