Data collected from State departments of education in the various States concerning public elementary and high schools for the year 1927-28 show increases in many of the principal items over those collected from the same source for 1925-26. A few show decreases. The information collected shows a tendency for elementary-school enrollments, high-school enrollments, number of teachers employed, total expenditures, and per-pupil cost, to increase less rapidly than they have in the past, and to approach a point whereby any increases will become insignificant in comparison with those the country has experienced since 1916. The major items presented in this bulletin include: (1) enrollments in elementary and high-school; (2) average attendance; (3) number of teachers employed; (4) total amount expended for public-school education for 1927-28; (5) number of school buildings; (6) data for reorganized schools; (7) length of curriculum; (8) night schools; (9) value of school property; (10) permanent school funds and school lands; (11) school indebtedness; (12) financial support; (13) distribution of expenditures; and many others.
