This directory describes tests available for use by psychologists, educators and human resource personnel in businesses. Each of the three main sections is divided into subsections. Psychology contains 21 subsections; Education, 49 subsections; and Business, 20 subsections. The tests within each subsection are listed alphabetically by title. Each test entry is structured as follows: test title and author/s; copyright date; population for which the test is intended; a purpose statement; a brief description highlighting the test's major features; format information; scoring method; relevant cost and availability information; and primary publisher. Five indexes are provided: an index of publishers; an index of publishers not in the fifth edition (but in the previous edition); an index of tests not in this edition); an index of authors; and an index of test titles.
