Preservice teachers can be considered simultaneously students and teachers and therefore likely have both academic and professional goals. However, once in a professional program, predicting professional outcomes becomes somewhat more important than academic ones. This distinction may have implications for the selection of measurement tools used in research on preservice teachers' motivation. We used a multitrait-multimethod (MTMM) design that included tests of alternative confirmatory factor analyses (CFAs), within and between method correlations, and relations with other variables to compare two measures of achievement goals: Elliot and Murayama's (2008) measure of students' achievement goals and Butler's (2007) measure of teachers' achievement goals. Results of the CFAs suggested that the scales are measuring separate constructs. The MTMM correlations, however, revealed evidence that certain factors may function similarly. This was most evident for the homotrait-heteromethod factors of mastery approach, which correlated similarly with sense of self-efficacy, emotions, and classroom mastery goal structures.
