This document outlines the 1985-86 Chapter I Corrective Mathematics Program in New York City. The program served 8,825 eligible students in 186 nonpublic schools. The major goals of the program were to alleviate students' diagnosed deficiencies in mathematical concepts, computation and problem solving and to assist students in applying these concepts and skills in everyday life. Students received instruction in groups of 8 to 10, 1 to 5 times per week. Program objectives stated that students would achieve an average gain of five Normal Curve Equivalents from pretest to posttest on standardized mathematics tests. The students' test results surpassed the success criterion. The document describes the program, reports student outcomes, presents conclusions and makes recommendations. (PK)
