The basic question addressed in this monograph is whether credentialing the preservice or inservice school based teacher educator is necessary and/or desirable. To study this question, a series of related issues were posed and investigated: (1) Is there a need for credentialing? (2) What institution would award the credential, and should recognition be local or statewide? (3) To what extent should individuals and institutions be required to participate in the credentialing system? (4) Would the credential be permanent or renewable? (5) What is the basis for the credential? (6) What procedures would determine the award of the credential? and (7) What would be the form of the credential? In Section I, each of the above issues is discussed. Section II reports a study of professional perceptions concerning each of these issues gathered from 152 educators. Texas teachers, administrators, and teacher educators in Houston, Galena Park, Abilene, Waco, and Tyler responded to a survey that was completed as part of a regularly scheduled professional meeting. The state Teacher Education and Standards Committee also completed the survey. Section III reports on the deliberations of 85 educators at a state SBTE conference in the spring of 1976. Twelve small groups worked independently to design a system for credentialing SBTE. Each of these proposals is described with general conclusions. Appendix A concerns the Credentialing/Recognition System for School Based Teacher Educators; Appendix B, the Recognition of SBTE; and Appendix C, a Recognition System for SBTE. (MM)
