This study was conducted to develop a valid and reliable measurement tool that can identify middle school students' self-regulation skills. Firstly, the literature was utilized in the development of the measurement tool. The form was finalized with the support of the opinions of different experts and a trial application. Then, the form was administered to 341 middle school students to determine its construct validity, and exploratory factor analysis (EFA) was performed on the collected data. Then, the form was administered to 341 middle school students to determine its construct validity, and exploratory factor analysis (EFA) was performed on the collected data. As a result of the study, it was determined that the scale consisted of 9 items and two sub-dimensions, namely "forethought" and "volitional control and self-reflection." In order to reveal the reliability of the scale, internal consistency, two-half test analyses, and composite reliability (CR) were used, and it was determined that the values found were .74 and above. In order to reveal the accuracy of the obtained structure, data were collected from 218 middle school students in a different province, and confirmatory factor analysis (CFA) was performed with these data. As a result of the analysis, the two-factor structure of the scale was confirmed. When the findings are examined, it can be said that the scale is a reliable and valid tool that can be applied to determine the self-regulation skills of students studying at the middle school level.
