The document discusses the Common Core State Standards (CCSS), which are a set of clear standards for math and English language arts adopted by most U.S. states. The goals of the CCSS are to ensure students are college and career ready by establishing consistent guidelines for what students should know and be able to do from kindergarten through 12th grade. The CCSS emphasize skills like critical thinking, problem solving, and analytical skills over rote memorization. Key shifts in instruction include focusing curricula, increasing text complexity, and requiring students to support answers with evidence from source texts.
