The work of the visiting teacher in the country's school system is rapidly becoming a professional service of significance in the realization of the objectives of education, namely, complete development of the whole child. Like many new services, this phase of pupil personnel work has had a Topsy-like growth without adequate safeguards as to placement in the school structure, as to qualifications of the officials performing the assigned functions and as to legal certification based on acceptable qualifications for designated functions in school systems. Recently renewed interest in this area of school, service has brought these shortcomings to the attention of school officials interested. The U. S. Office of Education, realizing the need and in answer to requests of school people in general, including officials of the American Association of School Social Workers (now the National Association of School Social Workers), initiated a questionnaire study of visiting teacher services in cities 10,000 and above in population to secure preliminary, information on the status of visiting teachers in the systems indicated. The results of the study are summarized and discussed in this bulletin. Appended are: (1) Questionnaire in regard to the visiting teacher or school social worker in city public school systems; and (2) Examples of State certification of visiting teachers.
