The purpose of this study is to adapt Adaptation of AIR Self-Determination- Educator Version The confirmatory factor analysis (CFA) of the scale, which was translated into Turkish and studied in terms of language validity, was carried out on 220 (46.8% female, 53.2% male) special education teachers. Teachers answer the items in the scale by thinking about their students. The age range of the participants in the study was between 25 and 59, and the mean age was 36.12 (sd ± 7.03). Sixty-four percent of the students reflected by the data in the study were female and thirty-six percent were male. According to the distribution of the disability groups, 24% of the students had autism and 76% had an intellectual disability. After establishing language, the validity and reliability of the scale of analysis was examined. Item-factor structure has been tested for compliance with a model by confirmatory factor analysis (CFA). Based on this, five-factor structure of Adaptation of AIR Self-Determination Scale - Educator Version has been validated. As a result of the analysis for adaptation of Adaptation of AIR Self-Determination Scale - Educator Version to Turkish, it can be said that the scale is a reliable and valid measurement tool. As a result of the measurement model, the t values of the indicators in the measurement model were between 10.02 and 16.36 and R2 values varied between 0.39 and 0.78. Cronbach's Alpha ([alpha]) internal consistency coefficient of the scale ranged between 0.86 and 0.94. The CR values of the subdimensions of the scale vary between 0.86 and 0.93, and the AVE values between 0.51 and 0.70.
