The Teacher Belief Q-Sort (TBQ) measures three aspects of teachers’ beliefs and priorities: Discipline and Behavior Management, Teaching Practices, and Beliefs about Students. The TBQ method offers the opportunity to describe characteristics of teachers as well as compare a group of teachers’ beliefs and priorities to an “ideal” teacher. The TBQ is particularly effective at assessing teachers’ priorities and beliefs as they change during the process of implementation of a new intervention. The Q-sort method offers an advantage as it is less susceptible to bias than traditional questionnaire methods.
