Several standard measures of aptitude, interest, attitude, and personality are briefly described, including the General Aptitude Test Battery, the Clerical Skills Tests, other tests sponsored by the United States Employment Service; and the Strong Campbell Interest Inventory. This volume also reviews special assessment techniques for the severely disadvantaged including 19 paper and pencil measures, 13 work sample systems, and two pretesting orientation exercises. Each review outlines format purpose, development, intended audience, norms, validity, reliability, application to an employment and training setting, and availability. Some tests, like the Nonreading Aptitude Test Battery and the Basic Occupational Literacy Test, have been extensively normed and validated with disadvantaged populations; others have not involved this group at all. (The appendix describes relevant reference works and information services.) (CP)
