The term "Common Core" refers to a set of educational standards that outline what students should know and be able to do at each grade level in mathematics, English language arts, and other subjects. These standards were developed by a group of educators, experts, and policymakers who worked together to establish clear and consistent goals for student learning across the United States. The goal of Common Core is to ensure that all students receive a high-quality education that prepares them for success in college and career.
