Project Apple Core (Adult Performance Level), a 15-month project funded through Section 309 of the Adult Education Act of 1966, was carried out in Lafayette Parish, Louisiana, to provide a career-oriented instructional program for undereducated and underemployed adults in that area. The document briefly describes some aspects of the project, in which employers, administrators, and supervisors identified undereducated employed adults, and instructional programs for them were implemented in a hospital, a packing plant, a Union, and a city public works department. Individual prescription programs for each student were developed, based upon: (1) a survey identifying necessary levels of competency, (2) supervisor interviews to identify each employee's specific academic weaknesses, (3) employee interviews to determine their specific interests, and (4) site visits. Paraprofessionals were hired, career-oriented math and reading curricula were developed, and instructional materials were compiled into instructional packets in the areas of Health Services, Private Industry, and Municipal Service. Communication between the agency and the supervisors provided feedback. An annotated bibliography was compiled, a dissemination conference held, and a slide presentation developed and shown for promotion, training, and recruitment. Sizeable gains were produced in educational levels among participants. The document does not contain the bibliography or the instructional packets. (AJ)
