This paper presents the rationale, structure, and specifications for a model program for the preparation of chemists, chemical engineers, and high school chemistry teachers. The model (an application of systems technology to program development in higher education) is based on the structure provided by the Georgia Educational Model Specifications for the Preparation of Elementary Teachers. The proposed instructional program is based on performance specifications related to the three chemistry-related occupations and is arranged in a three-phase career sequence (preprofessional, professional, and specialist). Emphasis is on (1) individualization of instruction through the use of proficiency modules (student contract units classified by type and blocks and arranged in appropriate sequence); (2) increased on-the-job laboratory experience in five types of laboratory facilities; and (3) the process of continuous and differentiated evaluation. Illustrative materials include: a conceptual model of job analysis, essential parts of a complete proficiency module (PM), essential parts of each PM learning task, specifications for various study sequences, and a conceptual summary network for development and evaluation of the model.
