This study presents development and validation of a new measurement instrument to explore student-teachers' self-efficacy beliefs toward teaching. We developed and administered a survey to 346 student teachers at Hacettepe University, Ankara, Turkey in the Department of Elementary Education in the spring term of the 2003-2004 academic year. The nature of the study is descriptive. The aim is to describe what the real situation is. Standard scale development methods and factor analysis were used. The results of the study were strongly supported by the validity and reliability of the survey. Cronbach's alpha was calculated and the reliability coefficient was 0.92. For purposes of examining content validity, the opinions of experts on 5 subject matters were taken. Factor analysis was made to elicit the fundamental dimensions of the survey. As a result of the Kalse-Meyer-Olkin and Bartlett test (0.93), factor analysis was administered to the survey. A single-factor model was specified for the structure of the survey as anticipated.
