Guidelines, as developed by the Association of Teacher Educators (ATE), for professional experiences in education are presented. Revisions of these guidelines were conducted by the National Field Directors Forum, a special interest group of the ATE. The major purposes of professional experiences are to: (1) provide opportunities to relate knowledge, skills, and attitudes learned in teacher education to direct experiences and to perform professional teaching duties; (2) provide opportunities to apply and test principles of learning and to apply teaching strategies; (3) provide opportunities to develop entry level competence in the full range of teaching functions; (4) provide opportunities for career exploration in the teaching profession; and (5) demonstrate principles of professional and ethical behavior. This booklet presents guidelines regarding: (1) organizational structures for professional experiences; (2) planning of professional experiences; (3) qualifications, responsibilities, and loads of college and university personnel; (4) qualifications and responsibilities of affiliated supervisory personnel; and (5) inservice education programs for supervisors.
