For the past twelve years, the School District of Philadelphia has conducted an annual evaluation of the projects funded under the Elementary Secondary Education Act Title I. Since 1973, the annual evaluations have been produced in two volumes - The Technical Report and the Abstracts. This volume contains abstracts of 31 project reports. The projects are organized into six categories which include: comprehensive reading, comprehensive mathematics, programs for limited-English-speaking-ability pupils, social sciences, supportive services and nonpublic school projects. Project categories are discussed in terms of programmatic goals, evaluation techniques, findings, summary and conclusions. Behavioral objectives are stated and student achievement is expressed as gains in grade equivalent units. Subtests of the California Achievement Tests (CAT) were administered to students in grades 2-12 as pre- (February (1979) and post- (February 1980) tests in reading comprehension and mathematics computation. Since the major thrusts of Title I are reading and mathematics, the total tests in these areas from 1974 and 1980 are used to examine the longitudinal impact of Title I. (RL)
