Launched in June 2009, the federal Common Core State Standards Initiative is designed to develop and implement a single set of national standards in english language arts and in math to define what every student should know and be able to do in order to be fully ready for post-secondary education or a successful career. Massachusetts played a leading role in the development and review of the standards. Curriculum experts and educators from across Masachusetts reviewed and submitted comments on drafts that were incorporated throughout the development process to ensure that the expectations set in the final versions met or exceeded the strong standards already in place for Massachusetts students.
