This study aimed at adapting the personal professional development efforts scale developed for science and technology teachers to be applied for middle school mathematics teachers. For this purpose, first of all, the items of the original scale were adjusted for the middle school mathematics teachers by a team of experts. Data obtained by the new scale format from the middle school mathematics teachers working in different regions of Turkey (N=117) were subjected to exploratory (principal components method) and confirmatory (primary and secondary level) factor analyses. At the end of these analyses, it was concluded that the scale with six factors does not originally remain the same and confirms the scale with five factors. Based on the reliability analysis of the final version, it was noted that Cronbach's Alpha value of the whole scale is .913. Accordingly, it was observed that the scale with five factors is applicable in terms of a study on the levels of personal professional development efforts for middle school mathematics teachers.
