This report presents both formative and summative data regarding the implementation and effectiveness of the Basic Skills Program carried out in the Montgomery County, Maryland, public schools in 1981. The program provides intensive remedial instruction in the basic skills areas of reading, writing, and mathematics to elementary (through grade 8) students who scored very low on standardized achievement tests. The report begins by providing background information, briefly describing the evaluation design and methodology, and outlining pupil characteristics (grade, level, race, sex, and achievement test scores). The following section deals with program organization and implementation, detailing instructional strategies, teacher expectations, pupil behavior, course objectives, content, materials, and planning. The final section of the report discusses parent perceptions of pupils' basic skills needs and program benefits. Appended are pupil descriptive data by summer school center and a 1981 Basic Skills Program calendar and workshop description. (WAM)
