The Model Accounting Plan (MAP) is a demographic accounting system designed to meet three major goals related to improving planning, evaluation, and monitoring of special education programs. First, MAP provides local-level data for administrators and parents to monitor the progress, transition patterns, expected attainments, and associated costs of students in special education. Second, MAP facilitates the aggregation of local data to inform decisions about special education at the state and national levels. Finally, the project has encouraged positive change in the way that data for special education are reported and used. Two articles arising from the project are appended. They are: "A Demographic Accounting System to Inform Educational Policy: Genesis, Dissemination, and Limited Acceptance" (Robert Rossi and Phyllis DuBois) and "Computer-Generated Educational Data: Nuisance or Opportunity?" (Phyllis DuBois and Robert Rossi). (PB)
