In this study, “Self Efficacy Beliefs Scale for the Implementation of the Constructivist Approach in Science and Technology Courses for Preservice Teachers” was taken for the study adapted to applicable to all teachers. After the necessary permission items of the scale were changed to applicable to all teachers, some experts’ opinions were taken in accordance with these changes. In light of the feedbacks given by the experts, some items were corrected. Subsequently a pool of items including a total of 41 items was given to the sample group. EFA was applied for the structural validity of the scale and the results of the EFA showed that scale consisted of four factors. In order to test whether the four-factor scale would be verified as a model, confirmatory factor analysis was conducted, and the structure of four-factor scale was confirmed. The reliability of the professional values scale was investigated through Cronbach Alpha coefficient and the reliability coefficients were found to be quite high. Consequently, it is seen that Teachers Self Efficacy Beliefs for the Implementation of Constructivist Approach Scale was a valid and reliable measurement tool
