This interim evaluation report presents an overview of Dade County (Florida) systems programs--instructional assessment and management structures which provide for the acquisition of reading and mathematics skills by individual students. A survey of the programs reveals that, as of 1974, 1660 installations had accommodated approximately 50,000 second-grade through sixth-grade pupils. Discussion also provides a description of evaluative procedures used; conclusions with regard to program implementation, program effects on pupil achievement, and reading and math systems; and recommendations for the future. Appendixes include planning inventories and procedural suggestions for both reading and mathematics systems, various information-retrieval forms used, and a cost analysis of systems programs. (KS)
