About This Book
Published in 1920, this report presents an index for measuring the effectiveness of state school systems by the amount of education received by the children and the expenditures made to purchase this education. The purpose of the index is to make it possible for state school systems to measure their progress from year to year and to compare their attainments with those of their neighbors.
