A school health program is usually thought of as comprising three broad areas: (1) health education, including both separate and integrated instruction; (2) healthful school environment, including both physical and social aspects; and (3) school health services. The study reported here deals with the school health service area of the school health program. Presented is certain information of a statistical nature regarding health service in school systems of the 3.430 cities in the Continental United States with populations of 2,500 and above. The findings in this study indicate that considerable increase has occurred since the last study in the number of school systems having health services and in the scope of their school health programs. The study also shows that much still needs to be done in the United States if all 30,000,00 school children are to have adequate school health service programs. Following an introductory section that covers the historical background of school health programs and previous surveys, the following topics are addressed: (1) Survey Procedures; (2) Number of School Systems Having School Health Services; (3) Administration and Financing of School Health Programs; (4) Personnel Available for School Health Services; (5) The Medical Examination; (6) The Dental Examination; (7) School Nursing Service; (8) Administrative Relationships of the Health Services to Health Instruction and Physical Education; (9) Extent to Which Schools Call upon Professional Groups for Advice and Council; and (10) Summary. This report should be of special interest to school administrators, school health service personnel, public health officials, medical and dental societies, parent-teacher associations, and many other individual groups. Appended are two questionnaires on surveys of school health services. A bibliography is also included. (Contains 31 tables and 12 footnotes.) [Best copy available has been provided.]
