The Texas adult performance level (APL) project LINK-FOUR implemented a curriculum based on functional competencies at four sites (Austin, Texarkana, Texas City, and Abilene) and formed linkages with local organizations involved in adult vocational education. The concept on which the project was based was that a set of prevocational skills, plus a set of vocational competencies, would better prepare adult students in their daily lives. Prevocational students involved in the project were clients of CETA (Comprehensive Employment and Training Act Titles I, II, and III), the Texas Rehabilitation Commission, and the Texas Department of Human Resources, as well as students completing their high school diploma or GED (General Educational Development) tests as prerequisites for vocational training. Instruments used to assess student needs and interests were the Student Interest Survey; the Test of Adult Basic Education Reading, Level M; the Adult APL Survey; and the Self-Directed Search. A survey (Pre-Voc) was also developed to assess students' reactions to APL materials after exposure to the curriculum. The report presents analyses of data on student needs and interests, a third-party evaluation of the project, and recommendations for successful implementation of educational linkage projects. (Appendixes include APL training materials, individual career planning form, and sample Pre-Voc survey and APL interview forms.) (YLB)
