The assessment of children's self-regulation skills in early childhood is important in terms of revealing their social, emotional and academic situations, distinguishing those at risk and taking precautions. The aim of this study is to create the Turkish form of the Self-Regulation Assessment Scale for Early Childhood (SASEC) developed by Boyer (2023) and to determine its validity and reliability for children aged 36-72 months. Data from the Turkish form of the scale were obtained from the evaluation of the self-regulation skills of 313 children (36-72 months) in preschool education institutions in various districts of Istanbul. According to the analysis results, SASEC has a single-factor structure. The factor loadings of the scale items vary between 0.760 and 0.853. The results show that the Cronbach's Alpha value of the 12-item scale is 0.95. The scale is used with a scale rating guide that allows the child's attitudes and behaviors to be evaluated. A high score from the scale indicates that the child has good self-regulation skills; a low score indicates the child's inadequacy in self-regulation skill.
