Described is Project COMP (Computerized Operational Materials Prescription), an individualized reading instructional program for educable mentally retarded (EMR) children in regular or special classes. The program is designed to correlate with the Wisconsin Design for Reading (WDR) and to utilize a diagnostic teaching specialist who uses specific reading instructional methods, materials, and techniques. A unique characteristic of the program is the provision to teachers of computer printout feedback which identifies reading skills accomplished, skills not mastered, and materials (with location) for subsequent instruction. The program is currently in use with 160 EMR, 347 disadvantaged, and 326 normal children. COMP consists of five components: the WDR (which has 45 objectives at four levels of progressive difficulty), periodic testing and feedback of results via computer printout, a computerized inventory of instructional materials, purchase of instructional materials appropriate to teach target skills, and inservice teacher education activities. Reported results show mean reading gains of the normal students from below average to above national norms and reading gains made with other programs for the EMR. Also noted are the cost ($10 per pupil), national recognition received, and positive evaluation in the Title VI Evaluation Report. (DB)
