In accordance with the subject of this research, three different scales to measure preschool teachers' performances with respect to school principals', parents' and children's point of view were developed for the research. 51 principals, 893 parents and 256 children participated in the research. "Teacher Performance Evaluation Scale-Administrators' Form" (TPESAF), "Teacher Performance Evaluation Scale-Parents' Form" (TPESPF) and "Teacher Performance Evaluation Scale-Children's Form" (TPESCF) are the scales that were prepared and used by the researcher. The data obtained were analysed by "SPSS 13 for Windows". The main results of the research are as follows: Research, an exploratory factor analysis was carried out for each of the scales developed. In order to show the validity of the scales, the overall and sub-test content validity analysis and differentiation power of the (TPESAF), (TPESPF) and (TPESCF) were calculated. Following the factor analysis which gave the scales their final shape, statistical reliability analysis was carried out. In this study, Cronbach Alpha coefficients of the (TPESAF), (TPESPF) and (TPESCF) and their sub-tests' means and standard deviations were calculated. Furthermore the test re-test reliability analysis was carried out. The scales were found to be reliable according to the reliability analysis (Cronbach Alpha Coefficients of Principal's Form: 0,94, Parents' Scale: 0,93, Children's Scale: 0,84).
