This bulletin deals with the establishment of selected administrative and specialized service positions primarily from the standpoint of State statutes. The investigation is centered on an analysis of State constitutional and statutory provisions that authorize selected administrative and specialized service positions. Administrative and specialized service positions in four areas: general administration, instructional supervision, pupil personnel, and school health comprise the group whose statutory existence is described. An analysis of statutory provisions that States have enacted to directly support these positions by financial means forms the second major area of the study. Four of the five chapters are concerned with the provisions that pertain to the establishment of the selected positions. The first chapter is an analysis of State legislation on general administrative positions. The second chapter discusses the statutory provisions for instructional supervisors and librarians. In the third chapter, provisions on pupil personnel positions are analyzed, and in the fourth chapter, those statutes that establish school health positions are discussed. The fifth chapter presents a discussion of provisions of statutes that relate to specific State aid supporting selected administrative and specialized service positions. The basic information comprising the source material for the chapters is given in the Appendix, which presents a State by State summary of statutory provisions and a few constitutional provisions as of July 1, 1958. Each State summary is organized so as to relate to the State's general classification of school districts and notes are included to clarify provisions of the statutes on staffing. Individual sections contain footnotes. (Contains 15 tables.) [Best copy available has been provided.]
