Common Core State Standards - What are they?  
Adopted by over 45 states in the U.S., the Common Core State Standards are a set of shared K-12 learning expectations for students in English-language arts and mathematics. These two new sets of content standards replace Oregon’s current standards in English language arts and mathematics. While the new standards are similar in ways to Oregon’s current standards, some content has been shifted and the level of rigor has increased to ensure college and career readiness at the end of high school.
