This program model describes a plan which provides continuous professional education and appropriate general and special liberal arts studies to meet preparation needs of (1) paraprofessionals (such as classroom and instructional materials aides), (2) professionals (assistant, associate, or intern teachers, classroom instructors), and (3) career professionals (including supervising or directing teachers of school aides and interns, instructional unit leaders, and college clinical instructors) whose professional work would contribute to the educational program in primary and middle schools. Included are brief job descriptions, premises upon which the model program is based, and an outline of the "different preparational programs to meet different entrance times into a professional sequence and different professional goals." A section on "Possible Model Structures for the Professional Clinical Experience Program in Cooperative Teaching Centers in the Public Schools" and one on "Cooperative Clinical Teaching Centers or Institutes as Centers for Education Professions Development and for Curriculum Innovation and Research" focus on the interinstitutional cooperation which would facilitate the clinical training experiences the program emphasizes.
