This handbook offers a succinct discussion of inservice training programs for noninstructional school personnel. The booklet is intended for use primarily by school business officials and was developed for that purpose from a doctoral dissertation on inservice training written by Dr. Donald K. Sorsabal. Separate chapters of the booklet examine the purpose and value of inservice training, the definition of inservice training, basic concepts and principles of inservice training, determination of training needs, different types of training programs, and critical requirements for training programs. There is also an extensive bibliography listing publications and other reference materials that may be useful in designing an inservice training program. (JG)
