Why Common Core State Standards?
The Standards-based Education movement of the 1990s did a great deal to sharpen our focus as we defined what we wanted students to know, understand, and be able to do by the time they graduated from our schools. However, this movement was disjointed and left each state to identify their own expectations. At the same time, the assessment and accountability movement had gained steam. States were facing accountability to the federal government but each state was essentially defining its proficiency level and determining what it meant to master expectations.
