This bulletin contains a report on the development of the rural junior high school. Since their introduction in 1909, junior high schools have steadily advanced in the favor of school administrators, and they now seem likely to cause a revolution in the organization of American secondary education. Among many other advantages claimed for them, it is said that they afford easy transition from the classroom of the elementary school to the departmental teaching of the the higher schools: that through them the introduction of the pupil to advanced methods of instruction is better timed with reference to his physical development; that they offer excellent means of exploration and of vocational guidance. In rural areas the development of junior high schools has lagged, although it appears that such schools should be especially suited to rural conditions. Study of the situation is clearly needed. The creation of the National Committee on Research in Secondary Education offered exceptional opportunity for such study, and at the instance of Dr. John J. Tigert, then Commissioner of Education, a subcommittee of that organization was constituted for the purpose under the chairmanship of Dr. Emery N. Ferriss. The report of the subcommittee is presented herein. (Contains 30 tables and 21 footnotes.) [Report of a Subcomittee of the National Committee on Research in Secondary Education.
