Because of the individual authority of each State for its own educational program, practices and policies differ widely among them in many respects. Yet in the midst of differences there are also common elements of development. The U. S. Office of Education, in presenting this series of monographs, has attempted to point out those common elements, to analyze the differences, and to present significant factors in State educational structure. In so doing, it accedes to the requests of a large number of correspondents who are students of State school administration and who have experienced the need for the type of material offered in this series. The report included in the present monograph deals with the kind of assistance given by State departments of education with regard to school plant problems. Until comparatively recently State departments of education did little to assist local communities on school plant problems. However, such assistance has become an increasingly important part of State department work because: (1) there has been a steadily growing recognition of the relationship of the functional planning of school buildings to the development of a well- rounded, modern curriculum; (2) the importance of adequate standards for lighting, ventilation, heating, etc., is more widely recognized; and (3) the movement toward large centralized schools instead of small one- and two-room buildings requires technical advice and direction which many local communities are not in a position to furnish. To describe the organization and functions of school building work in State departments is the aim of this bulletin, which is divided into the following three chapters: (1) Organization of School Building Work in State Departments of Education; (2) Functions and Procedures of State Departments of Education with Regard to School Building Work; and (3) Descriptions of School Building Work in 8 State Departments of Education. The following are appended: (1) Charts Showing the Location of School Building Work in 22 State Departments of Education; (2) School Building Surveys Published by State Departments of Education; (3) Bibliography of Printed Standards on School Buildings Published by State Departments of Education; and (4) Tables I through VIII. (Contains 24 tables and 9 footnotes.) [Best copy available has been provided.]
