The purpose of this research was to standardize the scale of emotional and social skills of teachers based on the model of positive psychology. The present research was conducted using a mixed research method. In the qualitative phase, a semi-structured interview was conducted with 18 experts and experts in the field of psychological and social competencies of teachers based on the model of positive psychology. The obtained data were analyzed using grounded theory method. 3 dimensions and eighteen components were the result. Based on the findings of the first part of the research, the scale was designed and tested. The quantitative stage consisted of the preparation of the pre-preliminary version and the preliminary version and the standardization stage of the scale. For this purpose, 234 items were written in the construction phase, and at the end of this phase, a preliminary scale with 126 items was prepared. In the standardization stage, the final version was prepared based on the data of a sample group consisting of 357 teachers and with 72 items. In addition, scales of psychological capital, job-related emotional well-being and reflective action of the teacher were used as tools to check the validity of the constructed scale. Checking the validity of the items, subscales and the whole scale of the final model showed that the range of internal homogeneity coefficients of the subscales is between 0.51 and 0.68. The correlation coefficients of the score of the designed components with the total score of the mentioned subscale are between 0.69 and 0.83. Therefore, according to the results, it can be said that the developed scale has sufficient validity and can be used in consulting and research collections.
