-19 against which the teacher competency is validated so that the measure of teacher behaviors could be used in the long run as a measure of teacher competencies. 2. Select competencies on a conceptual base, rather than by an eclectic approach. 3. When specifying competencies within a conceptual framework and designing research strategies to validate teacher competencies, it would be more economical to use training and evaluation systems already available. 4. Build research into the design for testing training materials and procedures. 5. Consider state coordinated inservice training. (49:1,6) The specialists concluded that research and development conducted in isolation of operational programs provides little information of value to decision makers (49:6). The rationale for PBTE derives from a consideration of Richard Turner's "Levels of Criteria." These levels clarify points at which feedback to teacher education programs could be generated and the points at which performance-based certification could occur. Criterion Level 1 is concerned with the long range effects of teacher behavior on changes in pupil achievement and well-being. Criterion Level 2 is concerned with changes in pupil behavior that can be effected in a relatively short period (one or two weeks) and under actual classroom conditions. Criterion Level 3 addresses itself to the effects of training on a teacher's behavior under actual classroom conditions. Criterion Levels 4 and 5 are concerned with the effects of teacher training
