This publication is designed to help vocational evaluators wisely select and use tests within the context of the referral questions and the individualized evaluation plan. The first of two parts contains information on why tests are used in evaluation, problems with tests, and how to select tests. Part 2 contains a review of specific tests that either have been found to be successful within vocational evaluation or have this potential. A total of thirty-six tests are included in the following areas: achievement batteries and reading tests; character and personality; intelligence; multi-aptitude batteries; vocations: clerical; vocations: interests; vocations: manual dexterity; and vocations: mechanical ability. For each test, the following information is provided: purpose, final score, description (including administration, content, and scoring), materials required, appropriate groups, technical considerations (including norm groups, reliability, and validity), American Psychological Association level, sources of information, availability, and comments. The addresses of the test publishers are appended. (LRA)
