An evaluative study was done of the supplemental education delivery system in reading and mathematics in the School District of the City of Saginaw (Michigan) at 28 schools. At the elementary school level the system includes push-in and pull-out programs in reading and mathematics and in reading intervention that served 2,494 students in grades one through six. At the secondary school level the system offers a self-contained classroom program for 838 students in grades 7 through 12 and a Thinking Skills Program for grades seven through nine. The program was assessed using a process evaluation involving monitoring throughout the year to determine if the program was being implemented as planned. The evaluation focused on supportive services using a questionnaire to gather information from 12 principals and assigned school social workers. Results found that successes included the following: (1) 41.2 percent believed the communication process for the program had improved; (2) the three most frequently mentioned activities/services of Project Success were after-school study centers (82.3 percent), mentoring programs (35.3 percent), and adopt-a-school (23.5 percent); and (3) 35.2 percent of principals rated their services either excellent or good. Appendixes contain the evaluation questionnaire, statistical information, program descriptions, and tabulated results of the questionnaire. (JB)
