This report contains statistics of 339 institutions which are engaged primarily in the preparation of teachers for positions in elementary and high schools. These institutions are classified as teachers colleges, State normal schools, city normal schools, county normal schools, and private normal schools.

The tables are similar in content to those published in previous bulletins on teacher-training institutions. The following exceptions are noted: (1) Date of establishment of institution and date of becoming a teachers college are given as furnished by the institution; (2) the number of institutional certificates are given according to the number of years of training required for such certificate; and (3) data are included to show the kind of work those in training are preparing to teach.
