A summer program designed for sixth, seventh, and eighth graders recommended as needing remediation or repetition met for three consecutive 90-minute sessions daily for 5 weeks. Regular school personnel staffed the 11 New York City schools designated as Summer Institutes and were assisted by guidance counselors and educational aides. Small classes and special services, including library services, were provided. Pretesting and post-testing were done with alternate forms of the Metropolitan Achievement Battery. For reading instruction students were grouped into basic and intensive reading programs according to pretest reading levels. They worked within a tightly structured curriculum emphasizing reading skills and mechanics. Emphasis in mathematics classes was on repetition of grades failed, with students grouped according to the grade they failed. Other subjects taught were English, foreign languages, sciences, and social studies. Some Institutes also offered subjects of a vocational nature. Results of a 1967 evaluation of six of the schools showed an average gain in reading of .3 year and an average gain in mathematics of .5 year. Attitudes and opinions of both staff and students concerning the program were favorable. References are included. (MD)
