Findings of teaching effectiveness research were related to the National Teacher Examinations (NTE) Test of Professional Knowledge (TPK). Delphi methodology was used to classify TPK items according to findings in a selected review of research. Six professors in teacher education completed a questionnaire to rate seven literature reviews. The three most highly related were presented to the Delphi panelists--three public school administrators and six college teachers from various areas of teacher education. In Phase 2, two panels of six experienced classroom teachers each considered half of the 104 TPK items in light of the selected review. Of the 104 TPK items, 20 were classified as supported by research; only 9 of the 20 were judged to require knowledge of that research. It is suggested that the TPK may be missing opportunities to measure important aspects of teachers' professional knowledge. Alternate strategies for measuring knowledge of teaching effectiveness research are considered for the planned successor to the NTE. Four tables contain study data. A 51-item list of references is included. (SLD)
