This paper reviews previous research on school finance reform in Illinois and examines the impact of various types of finance reform on suburban school districts as compared to urban and rural districts. The paper is divided into two parts. Part 1 reviews data from three previous annual evaluations of the results of the Illinois school finance reforms of 1973 and, based on these data, raises a number of research design questions about suburban school district analysis. Part 2 outlines situations in which suburban school districts might be expected to gain or lose from various types of school finance reform. (Author/JG)
