This data system was formulated to analyze school finance issues in New Jersey. It is intended for simulation and analysis of the effects of school finance reform. The system has three components. The first is the data base containing such information as district enrollment, property valuation, or financial information. The second is the aid allocation component that simulates the effects of aid allocation models. The analysis component analyzes the alternative aid allocation models. In the data base component, school districts are classified by socioeconomic factors and community type. The data system uses a data base management system that is flexible and will support a wide variety of analyses. The system is intended to analyze the impact of the present state aid formula; the impact of alternative measures of wealth, effort, or student need; and the impact of alternative state aid formulas. A simulation of alternative methods of taxation will also be possible. A glossary of terms used in the system concludes the report. (Author/JM)
