This document describes a study that designed, developed, and evaluated the Pennsylvania school-district database program for use by educational decision makers. The database contains current information developed from data provided by the Pennsylvania Department of Education and describes each of the 500 active school districts in the state. PEP PC was designed to enable easy accessibility of data for viewing and comparing school district information. A preliminary version of PEP PC was tested through a series of user tryouts, conducted at the individual, small group, and site levels. Data were collected through interviews, observations, a user's survey, and users' post-tryout software evaluations. Findings of the user's survey indicate that the microcomputer operating system used by PEP PC, the IBM compatible system, was available to 89 percent of district administrators. The field tests showed that district administrators preferred a microcomputer database program that is user-friendly. The availability of district information can provide the basis for comparing the conditions of school districts and act as a powerful tool for district assessment, planning, and decision making. Three tables and three figures are included. Appendices contain copies of the database evaluation form and user's survey. (LMI)
