The purpose of this report is to explain the procedures by which the Chicago public schools have attempted to equalize local school per-pupil costs. It is a case study designed to illustrate what one urban school system is doing to finance equity among schools. There are five major considerations related to the program to equalize per-pupil costs: distribution of resources, development of comparable per-pupil cost data, action to equalize per-pupil costs, analysis of per-pupil cost data, and need for evaluation. Four specific programs were promoted to equalize per-pupil staffing costs: the maximum class size program, the equalization program, the Elementary and Secondary Education Act comparability program, and the moratorium on teacher transfers. Statistical analysis of the 1972-73 data is presented in an appendix. (Author/IRT)
