A few years ago the public schools made no provision for the education of the blind, crippled, or mentally deficient, but now in New York City alone there are more than 100 classes for mentally peculiar children, while arrangements are rapidly making for the care of crippled and other classes of physically handicapped children. It was only as recently as 1909 that the first open-air school for tuberculous children was opened in Providence, but to-day such schools may be found in something over 40 cities. The special study of the mentally deficient child has engaged the attention of public-school educators for a period of less than three years, but at present plans are rapidly making in many progressive towns and cities for the careful study of such children by the employment of exact psychological methods. All these facts are interesting and significant, it must not be forgotten that no uniform methods of health organization in schools have been evolved, and that there still exist the most widely divergent beliefs and practices in this respect. Health work in schools needs standardization. The experiences of cities already organized in school health matters ought to be studied by other places attempting such organization for the first time. This bulletin discusses how organized health work in schools evolved. It contains the following parts: (1) Organization for Health Supervision; and (2) State Organization of School Hygiene in Minnesota. Appendix includes: Blanks and form for records, parents, notices, etc. A bibliography is included. Individual sections contain footnotes. [Best copy available has been provided.]
