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 material included in the present monograph deals with developments of State educational administration and supervision in the various phases of health work and physical education. Interest in such fields began a century ago but it has been stimulated to activity under special personnel within the past 25 years. In this study, the history of such supervision is traced, its statutory background is sketched, and details concerning the methods now in use are described. (Contains 12 footnotes.)
