The Common Core State Standards (CCSS), launched in 2009, establish consistent educational guidelines for K-12 students in math and English Language Arts across participating states, addressing the lack of standardization in previously adopted state-specific standards. The CCSS emphasize critical thinking, communication, collaboration, and creativity while defining expectations in reading, writing, speaking, listening, and language skills from kindergarten through 12th grade. Additionally, the document outlines assessment practices to evaluate student progress and ensure alignment with the CCSS.
