Subak local wisdom is the Balinese agricultural culture that has been declared by UNESCO as a world cultural heritage. Subak which is based on the philosophy of Tri Hita Karana has social, religious and ecological values and serves as the basis for a harmonious community life. This study aims to determine: (1) the level of knowledge and understanding of social studies teachers about subak, and (2) social studies teachers' attitude towards the idea about developing social studies learning models based on subak local wisdom. The study sample consisted of social studies teachers who were determined by purposive sampling. The research instruments were a semi-structured test and attitude questionnaire based on the Likert scale. Data were analyzed by quantitative descriptive techniques. The results showed that: (1) the majority of the teachers had a low level of knowledge and understanding about subak (47.50%); the remaining 32.50% are classified as moderate and only 20% are classified as high. (2) The majority of the teachers (77.50%) stated that they never used subak as a social study learning resource. (3) The teacher's attitude towards the idea of developing the social studies learning model based on subak local wisdom was very positive, where 97.50% expressed a strong agreement. The implication of the research is that further research needs to be done with a focus on developing social studies learning models based on the local wisdom of subak.
