The major goal of Project IMPACT (Improve Minimal Proficiencies by Activating Critical Thinking) is to improve student achievement on district tests of basic skill competency. The program seeks to improve student performance on tests requiring critical thinking with emphasis on reading and mathematics. Students involved in Project IMPACT work in a structured environment that accommodates individual styles of learning and are involved in learning tasks that move from the concrete to the abstract. This monograph provides information on: (1) the organization of IMPACT and curriculum materials included in the IMPACT kit; (2) classroom instructional activities; (3) implementation requirements (staffing, staff development, inservice training, technical assistance, cost and availability of materials); (4) history of IMPACT and evaluation procedures used in validating the program; (5) time line for installing the program; (6) addresses of schools or districts that have adopted the IMPACT program; (7) funding sources; and (8) a bibliography.
