This report contains statistics for 1926-27 of schools for delinquents. The institutions are of a reformatory nature, and receive inmates committed to their care by juvenile and other courts. Reports were received from 158 institutions out of 173 believed to exist. The number of instructors reported for the year is 1,488, of which number 582 are men. These persons are engaged primarily in the instruction of inmates. The assistants numbered 4,677 in 1927, of whom 2,529 were men. These assistants do no teaching, but care for the inmates. The bulletin concludes that one hundred and thirty-nine institutions report both the number of inmates discharged (27,530) and the number discharged that could read and write (27,385). This would indicate that 145, or 0.5 per cent of those discharged from these institutions were illiterate. This is considerably below the average for the United States, although there are probably differences in the definition of illiteracy in each group. (Contains 11 tables.)
