A second determinant of costs is the size of the class. One of the simplest ways of reducing expenses is to give a single teacher a large number of pupils to care for. In 1916 the superintendent of schools in St. Louis calculated that the reduction of elementary classes in the schools of that city by an average of one pupil per class would cost the city $65,000 per year. Los Angeles and Indianapolis have small elementary classes, the averages being 23.7 and 24.7 members per class respectively. The cost of elementary instruction is very high, being $59.41 and $50.45 respectively. St. Louis and Chicago have much lower costs, namely, $37.21 and $37.58 respectively. These low costs are secured in a very large measure by grouping children in large classes of 37.6 and 40.3 average membership per class.
