Investigations into the legal validity of the content and procedures proposed in the Teacher Performance Assessment Instruments (TPAI) and allied materials for use in certifying Georgia's beginning teachers are reported. TPAI was designed to determine how well teachers can demonstrate certain minimum teaching skills considered essential to effective teaching. The report focuses upon a survey of reference materials requisite to a preliminary understanding of potential legal problems arising when the proposed assessment system and materials are eventually implemented officially by the State Department of Education. Thirty-two court cases dealing with due process and equal protection in reference to teacher assessment are cited and discussed in tabular format. A summary of findings from this survey of litigation is presented. (JD)
