The purpose of this study is to examine the relationship between university supervisors’ predictions and teacher candidates’ performance on a summative assessment based on a capstone teaching event, part of the Performance Assessment for California Teachers (PACT). The findings indicate that university supervisors’ perspectives about their candidates did not always correspond with outcomes on the PACT teaching event, a summative performance assessment. In addition, most of the candidates with the highest and lowest scores on the assessment were not those for whom the supervisors anticipated outstanding or poor performance.
