Statistics of kindergartens and of elementary and high schools, supported by public funds in the various States, are given in this report. The major items presented include total enrollments, high-school enrollments, average daily attendance in all schools, number of teachers, number of school buildings, value of school property, and expenditures. The data are for the school year 1924-25, except for two states, Arizona and Wyoming, which are for 1923-24. Data for private schools are not included because they are incomplete. Since 1925 marks the close of the first quarter of the twentieth century, advantage is taken of the opportunity to review the progress made in that period and to show a few of the trends.
