Outcomes of 1990-91 Arizona At-Risk Pilot Project for grades K-3 and 7-12 are described in this third in a series of annual evaluation reports. The evaluation focuses on effective strategies in the context of the total school environment, examining both implementation processes and outcomes. Following an introduction, chapter 2 describes the evaluation methodology. Data were derived from student profiles, program narratives, district-reported participation, teacher and 7-12 student surveys, interviews, a cohort study, and retention and budget information. The third chapter provides descriptions and evaluation results of the K-3 at-risk programs, including attendance, academic achievement, and promotion/retention. Information on the 7-12 programs is presented in chapter 4, focusing on delivery systems, services, and student outcomes. A budget analysis is provided in chapter 5, and a summary and recommendations are offered in the concluding chapter. Findings indicate the overall positive impact of the K-3 and 7-12 pilot programs; identify regional differences; and demonstrate the importance of implementation for program success. Forty-six tables and 19 figures are included. Appendices contain K-3 and 7-12 supplemental data, budget data, and limitations of data sets. (22 references) (LMI)
