Over the past decade, public universities' expenditures for research and public service activities have increased faster than overall expenditures. This report presents information on direct expenditures for instruction, research, and public service at Illinois public universities during fiscal year 1992 and compares these findings to measures of related activities as suggested by the productivity guidelines issued in 1992. Data tables present the following: (1) fiscal year 1992 expenditures for instruction, departmental and organized research, and public service by each public university campus; (2) expenditures in each of these three categories as a percent of total state funded expenditures; (3) amounts spent on research by institution; (4) public university expenditures for doctoral instruction and organized research activities by institution; and (5) public university expenditures for public service by institution. The data suggest that public universities have allocated an increasing proportion of budgets to research and public service activities. Suggestions are made for realigning priorities that are consistent with institutional missions, to improve the productivity of each of these areas, and to reinvest resources into instructional programs, particularly undergraduate education.
