This directory was compiled to assist vocational teachers and researchers in locating tests in various occupational fields. Test data was gathered from publishers, directors of vocational programs, union officials, and members of the American Vocational Association. Selection of the instruments depended on their availability and standardization, although a few restricted instruments and non-standardized "item-banks" are included. Several "Trainer-Tester" devices and similar performance measures are also included. The tests are presented within eleven broad fields of vocational education. Each test annotation includes title, author, publisher, cost, forms available, administration, and a brief description of the test items. A key word index is provided to facilitate test searches. (PR)
