One of Them is caused low competence of teachers in applying HOTS in the subject. Therefore, we need a method to improve teacher competency. One method used is to optimize training HOTS development in the Subject Teacher Forum or called MGMP using the Realistic Mathematics Education approach. This research includes preliminary, prototype, and field tests. This research is on high school mathematics teachers in East OKU Regency. Analysis of this research data using a walkthrough, documents, and tests. The results of this study prove the increase in teacher competence in generating valid HOTS questions. Valid is when all validators said HOTS problems that are generated both in content and construct, practical (questions used for student learning, easy to read, do not attract diverse interpretations, and can be given to all students).
