This evaluation provides a project description, principal objectives, a listing of activities and services, and aspects of communication of eight nonpublic school centers providing supplemental instruction in corrective reading, language, and mathematics to students deficient in these areas because of economic, linguistic, or environmental isolation. Standardized test results show an increase in academic achievement. Other successful outcomes include improvements in communication, program expansion to meet diagnosed individual needs, improvements in pupil self-image and attitudes, and supplementary assistance to students through paraprofessional support. Among the problems listed are student frustration resulting from failure to achieve in a group situation what is successfully gained in an individualized center; problems in scheduling, especially for grades 7 and 8; and below average mean grades despite general growth. Recommendations include staff orientations to clarify programs and to improve scheduling, a reevaluation of services offered in grades 7 and 8, and selection of new test measures in language arts specifically for grade 1 students, for foreign background students, and for the high school center.
