A comprehensive instructional system to meet the needs of students of differing achievement and grade in the same classroom, this program is characterized by an innovative management system, procedures for continuous assessment of educational needs and achievement, a curriculum based on individual needs, and an emphasis on parent and community involvement. Called Meeting Students' Needs in the Multi-age Group Environment (MSN), the project served 205 students in first, second, and third grades of the Murch Elementary School in Washington, D.C. The evaluation described here focused on implementation of the program, student academic achievement, and self-reliant behavior. Data were gathered through observation, questionnaires, and student achievement tests. Evaluators concluded that (1) the program is meeting student needs in a multiage environment; (2) it can be replicated at other grade levels; (3) parents would like the program expanded to include more children; and (4) there is high parent participation in the program. No appropriate instrument was found to be adequate for the measurement of self-reliance, so such an instrument is being developed. (Author/JM)
