An evaluation is presented of the Collaborative Consultation Support System Program (CCSSP) which was developed to provide support to public schools in need of assistance. The school in which the program was established consisted of students who were mostly from poor and culturally diverse families. For the purpose of improving instruction, 18 teachers were "paired" to work together. The pairs were comprised of at least one experienced teacher and one probationary teacher. The objectives of the CCSSP were: (1) provide beginning teachers with a strong knowledge base to make them more effective; (2) train selected experienced teachers in a collegial, coaching, supervision/observation process; (3) establish a process of ongoing peer coaching, staff development and support for teachers in the school; (4) develop a cadre of teachers and administrators who can help others apply the teacher effectiveness research; and (5) improve overall student achievement in mathematics and reading. In this report the proposal for the program is outlined and the program rationale is described. An evaluation of the program includes descriptions of program activities and findings obtained from interviews with the participants, surveys that evaluated the program training, and an analysis of student scores on standardized tests.
