This monograph on Comprehensive Employment and Training Act (CETA) program models for practitioners in community-based government employment and training programs describes a model for classroom job training, the Opportunities Industrial Centers (OIC) model. The content is presented in five sections. The introductory section discusses motivations for classroom training, classroom training in employment and training programs, the OIC approach, and the Comprehensive Employment and Training Act (CETA). Section 2 covers the advantages, disadvantages, and preconsiderations for classroom training. The third section discusses the ingredients of classroom teaching, including client-centered instruction, team teaching and assessment, and interagency linkages. The next section, presenting a profile of classroom training, covers the training environment, instructors and job relatedness, open entry/open exit, and individualized instruction. Section 5 concludes with patterns for classroom training and includes pre-employment classroom training, classroom/work experience training, post-employment training, and evaluation of classroom training.
