| Abstract | Teacher efficacy has proven to be an important variable in teacher effectiveness. It is consistently related to positive teaching behaviors and student outcomes. However, the measurement of this construct is the subject of current debate, which includes critical examination of predominant instruments used to assess teacher efficacy. The present study extends this critical evaluation and examines sources of measurement error variance in the Teacher Efficacy Scale (TES), historically the most frequently used instrument in the area. Reliability generalization was used to characterize the typical score reliability for the TES and potential sources of measurement error variance across studies. Other related instruments were also examined with regard to measurement integrity. The 52 articles selected yielded 213 useful observations, and 86 reliability coefficients. Findings suggest that the psychometric difficulties of the general teaching efficacy subscales are problematic with regard to measurement error, but that the TES, with one subscale exception, yielded the most variable reliability coefficients of all the instruments.
