This companion volume to the authors' Assessing Teacher Competency provides schools of education, teacher induction programs, and school districts with the safe, valid, and reliable framework for assessing and measuring teacher dispositions that they have long sought. Teacher affect and disposition have always been more difficult to define and measure than teacher knowledge and skills (competency), but together those three measures define the standards of best practice set by NCATE, INTASC, and NBPTS. The authors' 5-step DAATS model for measuring teacher affect and dispositions is research based, field tested, and presented in a step-by-step sequence with worksheets, training activities, and examples from both pre-service and in-service settings. The DAATS model for assessing teacher dispositions may be used on its own, or it may be used in conjunction with the authors' CAATS model for assessing teacher competency (knowledge and skills) as part of a comprehensive assessment system.
