Provided are some of the proceedings of a conference on assessment of competency based teacher education (CBTE) programs in special education. Presentations by conference participants cover the following topics: research findings regarding evaluation and validation in performance based teacher education (Robert S. Soar); the New York state education department's assessment plans required in teacher education program proposals (Vincent Gazzella); the application of systematic observation methods (such as computer assisted teacher training) in research and training in special education (Melvyn I. Semmel); and models for research and development in performance based teacher education (Frederick McDonald). Summaries are provided of potential contributions and concerns regarding assessment processes of public school teachers (James G. Ward), public school administrators (Gilbert Duken and Michael Solimando), and teacher education students (Karen Cochran, Nathan Glasper, Karen Kowalchuck, and Margaret Maxwell). Also included are worksheets (Patricia M. Kay) which are noted to be based on a model for building an internally valid assessment system. In a conference evaluation (Alice Kornblith and Cecile Segal), it is concluded that although the conference was well organized, more technical expertise and individual consultation were needed. (SB)
