The ALL WIN-U.S.A. Project, administered by the Office of the Los Angeles County Superintendent of Schools (OLACSS), was to provide basic-skills instruction in reading and mathematics that would result in significant improvement in the respective achievement domains, in learner attitudes, and cost effectiveness relative to the previous curriculum and instruction. The OLACSS selected the New Century Education Corporation to provide the major elements of the educational program which has three major components: (1) individualized learning centers; (2) a mathematics and reading curriculum covering all grade levels, delivered in an individual and prescriptive manner; and (3) a preservice training institute for teachers and administrators. The New Century program was installed at 48 schools that met OEO eligibility requirements. Fiscal data for this study were collected from the various school districts in order to determine those program costs that had been paid from district funds. Outcome data collected as a part of the initial ALL-WIN evaluation were utilized for considering the effectiveness of the program. Data from various of the outcome determinations are summarized in this report but unique analyses have been performed only for three of the cognitive achievement measures. (MV)
