This document discusses various aspects of the training and utilization of "teacher aides" (used here to refer to the paraprofessional, lay assistant, nonprofessional, teacher helper, assistant teacher, or auxiliary personnel whose work may include "all those functions the non-certificated person might perform in the educational enterprise"). It is based largely on the conclusions reached in task-oriented conference discussions by teams of participants which included school board members, superintendents, principles, teachers, counselors, teacher aides, and representatives of professional associations. Following a position statement by the Colorado State Board of Education taking a positive stand on the utilization of teacher aides in Colorado schools, there are sections on pre-planning for the use of teacher aides; recruitment, selection and placement; preservice education; inservice education; possible functions of aides (who may assist with classroom work, home-school interaction, counseling, reference center or library services, technical services, or general school services); career development of aides; the team approach; and evaluation of research. Included also are a 56-item list of selected readings on "Teacher Aides in Education" and "Colorado Statutes Related to the Employment of Teacher Aides." (JS)
