The purpose of this report is to bring together and to summarize statistical information published in other chapters of the Biennial Survey of Education, and to present some new material that does not belong exclusively to any other statistical report. Data on public elementary and secondary schools are furnished by State departments of education. Data on private elementary schools are furnished by State departments of education, by the National Catholic Welfare Conference, and by a few individual reports from schools. Statistics of private and parochial secondary schools are furnished by State departments of education, by city school superintendents, by the National Catholic Welfare Conference, and by reports from practically all the schools included under this description. City school superintendents and their business managers report considerable data concerning schools in urban localities. The college, university, professional school, and teacher-training school authorities report upon their own institutions. Information for special schools, such as schools for delinquents and defectives, is reported by the schools having classes for these groups. Data for Indian schools are furnished by the Indian Office. (Contains 7 tables.) [Best copy available has been provided.]
