THIS REPORT EVALUATES THE PROGRESS OF 14 PILOT INTERMEDIATE SCHOOLS ORGANIZED IN SEPTEMBER 1966 INTO EITHER A 6-7-8 OR A 5-6-7 GRADE STRUCTURE. NINE OF THE SCHOOLS SERVE CHILDREN IN ECONOMICALLY DISADVANTAGED AREAS. A SPECIALLY REVISED CURRICULUM WAS INTRODUCED INTO THE PILOT SCHOOLS AT THE SIXTH-GRADE LEVEL. EXTENSIVE TEACHER TRAINING PRECEDED THE PROGRAM. DATA WERE GATHERED ASSESSING (1) THE EXTENT OF INTEGRATION IN THE PILOT SCHOOLS, (2) SCHOOL PERSONNEL AND FACILITIES, (3) SCHOOL ORGANIZATION AND SERVICES, AND (4) CURRICULUM. ALSO EVALUATED WERE THE REACTIONS OF SIXTH-GRADE PUPILS AND THEIR PARENTS TO THE PROGRAM. THE READING ACHIEVEMENT OF SIXTH-GRADE PUPILS IN PILOT AND NONPILOT SCHOOLS WAS MEASURED BY THE METROPOLITAN READING TESTS, BUT NO APPARENT DIFFERENCES WERE FOUND. HOWEVER, THE PROGRAM IN GENERAL SEEMED TO HAVE HAD "SOME SUCCESS." THE GREATEST PROBLEMS WERE LACK OF WELL-TRAINED TEACHERS, HIGH TEACHER MOBILITY, INADEQUATE SCHOOL FACILITIES, STATIC ETHNIC PATTERNS, AND HIGH PUPIL TRANSIENCY. TEST SCORES AND OTHER RELEVANT DATA ARE APPENDED. (AF)
