This 13th in a series of guides for planning facilities for educational programs is intended for use in the preparation of educational specifications for facilities for dental assistant programs. Designed for use by those responsible for planning facilities, the guide can also be used for instructional purposes in universities, colleges, seminars, and institutes. Pivotal questions about the educational program to be offered are posed, and the answers to these bear directly on the numbers and kinds of instructional areas needed to meet the program requirements. Much of the material is presented in checklist form which allows for consideration of alternatives in facility planning. Part I is a discussion of major purpose, underlying assumptions, and guiding principles. Part II gives information on dental hygiene training objectives and the kinds of programs which will be organized to implement them. Part III describes the actual spaces desired to house the program. Part IV is an annotated bibliography of reference sources which offer a more detailed treatment of the various phases of facility planning. "A Guide to Systematic Planning for Vocational and Technical Schools" (ED 026 537) is a related document. (JK)
