Various methods have been performed to identify teachers' attitudes towards assessment. Recognizing the idea that mapping is one of the most efficient tools, this study was aimed to investigate the effectiveness of attitude maps in the evaluation of teachers' attitudes towards assessment. The instrument, composed of open-ended questions, was utilized during the semi-structured interview protocol and used as the study's data collection tool. Attitude maps were constructed during the evaluation process to represent the pre-service teachers' attitudes' towards assessment. The participants' attitudes were determined and categorized as traditional, close to traditional, transitional, close to constructivist, and constructivist. Criterion validity of the results was achieved by comparing the categories drawn from the attitude maps with the categories derived by the survey. Results indicate that attitude mapping is a useful way to evaluate teachers' attitudes towards assessment. (Contains 1 table and 3 figures.)
