The Response to Educational Needs Project (RENP) focuses on training teachers as a vehicle for promoting student achievement in a compensatory education program. This document supplements a report on RENP replication and provides information on cost analysis, methodology, and sample and data collection. In Appendix A the following questions are addressed: (1) How much does RENP cost? (2) Does RENP supplement or supplant resources? (3) How do the costs of RENP distribute among the various organizational levels? (4) Do RENP resources vary between sites? (5) Have there been problems in acquiring resources? How have these problems affected RENP? and (6) What is the optimal/desirable level and mixture of resources in RENP? Also examined are the RENP organizational structure, facilities, equipment, miscellaneous cost categories, allocation of administrative costs, reading and mathematics laboratories, and community organizers. The resource approach to cost analysis, including types of cost considered, total versus incremental costs, unit of analysis, and base-year prices are described in Appendix B. The cost model is explained in terms of allocation procedures, problems with junior high schools, and unit costs (treatment of capital costs, facilities, furniture and fixtures, equipment, materials, and personnel). Details of the sample and the data collection procedures and cost data in table form are provided in Appendices C and D. (Author/MC)
