Ohio educators, many of whom engage daily with Ohio students, drove the process to make improvements to Ohio’s Learning Standards for Social Studies as part of a periodic review. In many cases, the changes reflect instruction already taking place in Ohio’s classrooms. The clarifications in the 2018 standards will guide districts in modifying, but not replacing, their existing local curricula, instructional plans and materials. In addition to the standards, the updated Social Studies Model Curriculum will provide additional resources to help educators learn about, and begin using, the standards.
