Outcome data are presented for students who participated in the 1985-1986 College Discovery and Development (CDD) program, which is affiliated with the City University of New York, and provides basic skills instruction in reading, writing, and/or mathematics. Information is included on the participants rate; reading, writing, and mathematics test results; and attendance by school and by grade. Full-year students were tested with standardized, norm-referenced tests, while half-year students were assessed using criterion-referenced tests. Pretest and posttest scores were used to determine program effectiveness in remediating basic skills deficiencies. For 1985-1986, 647 students from three Chapter 1-funded high schools participated in CDD reading and writing classes, and 296 students received CDD mathematics instruction. CDD met its overall program evaluation objectives for full-year and half-year writing students and for half-year mathematics students, but not for full-year mathematics students. Of full-year students with valid scores, 67% met the reading objective. In writing, 81% of full-year students and 77% of half-year students met the objective. Of those with complete mathematics results, 63% full-year and 79% half-year students met the objectives. (Author/SW)
