PRESENTED IS AN EVALUATION OF A 6-WEEK SUMMER SCHOOL PROGRAM FOR 502 DISADVANTAGED STUDENTS ENTERING JUNIOR HIGH SCHOOLS IN THE FALL OF 1966. PROGRAM GOALS WERE TO RAISE ACHIEVEMENT LEVELS, REDUCE SUMMER LEARNING LOSSES, ENCOURAGE ASPIRATION AND MOTIVATION FOR LEARNING, AND PROVIDE ENRICHMENT. THESE OBJECTIVES WERE IMPLEMENTED BY INTENSIVE REQUIRED CORE PROGRAMS IN READING, LANGUAGE ARTS, AND MATHEMATICS AND BY SOME ELECTIVE CLASSES. FIELD TRIPS, FREE NUTRITIONAL SNACKS, GUIDANCE PERSONNEL, A READING CONSULTANT, AND A NURSE WERE ALSO PROVIDED. THE APPRAISAL OF THE PROGRAM IS BASED ON PRE- AND POST-ACHIEVEMENT TEST RESULTS, STUDENT, TEACHER, AND PARENT OPINIONS AS MEASURED BY QUESTIONNAIRES, ATTENDANCE RATES, AND DESCRIPTIONS OF THE SPECIAL SERVICES. DROPOUT AND ABSENCE RATES WERE HIGH. MOST OF THE 22 TEACHERS FELT THAT STUDENTS HAD MADE "SOME" IMPROVEMENT OF A "SATISFACTORY NATURE," ESPECIALLY IN MOTIVATION AND ATTITUDE CHANGES. TEACHERS ALSO FELT THAT CLASS SESSIONS WERE TOO LONG AND THAT THE PROCEDURES FOR SCREENING AND SELECTING STUDENTS NEEDED IMPROVEMENT. MOST OF THE STUDENTS AND PARENTS SEEMED SATISFIED. THE MAJOR USE OF THE GUIDANCE SERVICES WAS FOR DISCIPLINE PROBLEMS. TEST RESULTS SHOW GAINS IN ALL AREAS EXCEPT SPELLING. (NH)
