The Common Core State Standards (CCSS) are a set of high-quality academic benchmarks in mathematics and English language arts/literacy (ELA) designed to ensure students across the United States receive a consistent and rigorous education. Developed by education experts and stakeholders, the CCSS emphasize critical thinking, problem-solving, and analytical skills essential for college and career readiness. The CCSS can be used to align curriculum, guide instruction, assess progress and foster equity.
