The Texas Network for Preparing School Based Teacher Educators (SBTEs) is a statewide cooperative effort of forty teacher centers, governed by an advisory board of fourteen members, and devoted to the improvement of instruction in elementary and secondary schools through improved practice of SBTEs. The SBTE is defined as being a professional educator, with responsibility for either preservice, inservice, or continuing teacher education, and whose primary base of operation is in the elementary or secondary school. The program is dedicated to (1) improving teacher education in Texas by developing competency specifications and instructional resources for the SBTE, (2) organizing a cooperative network among Texas Teacher Centers which supports SBTE development, and (3) demonstrating and studying a program involving a consortium of consortia. The four major program thrusts are network building, competency specifications, credentialling systems, and instructional systems. Each of these activities is described in detail. Evaluation studies of program effectiveness, program budgeting factors, and program outcomes are summarized. (MJB)
