Presented is an evaluation of the 1985-1986 Clinical and Guidance Program which provided a variety of diagnostic and counseling services to 10,536 students enrolled in Chapter I remedial instructional programs in 201 nonpublic schools in New York City. The report notes that the Chapter I Evaluation Model A was used to determine the impact of counseling services on student achievement in kindergarten through grade 12 in reading achievement, mathematics achievement, or linguistic skills. The objective criteria were gains of five Normal Curve Equivalents on norm-referenced achievement tests or statistically significant gains between pretests and posttests on criterion-referenced tests. Findings showed that most students in the corrective reading program, the reading skills center program, the corrective mathematics programs, and the English as a second language program made statistically significant and educationally meaningful mean gains. Students' mean scores on the Behavior Checklist decreased by 10.8 raw-score points, indicating a statistically significant improvement in behavior. The findings demonstrate that, in general, the program reached its goal of helping students resolve social and emotional problems that could disrupt learning and academic performance. A list of recommendations and 22 tables are included. (NB)
