We have completed the first steps in the accreditation process between HighScope Educational Research Foundation and Hisar Preschool. During the 2022-2023 academic year, our preschool administrators and a group of preschool teachers completed the 120-hour PCC (Preschool Curriculum Training) program. Then, HighScope curriculum trainings were transferred to Hisar Schools Preschool teachers through in-service trainings and curriculum revisions were completed. In line with our goal of high quality education at Hisar Schools, our comprehensive work in our accreditation process continues effectively.
