Map: Tracking the Common Core State Standards

Confused about the status of the Common Core State Standards? You’re not alone.

Since we published an update last year about the status of the English/language arts and math standards across 50 states and the District of Columbia, there’s been a fair bit of activity regarding the standards. Although the national backlash to the common core seems to have cooled a little bit in recent months, several states have announced some kind of change to the standards due to state legislation, governors’ directives, or other reasons.

The map below represents our best judgment about the nominal status of the common core across the country. In addition to the map, see our drop-down menu below for information about how different states are handling the common core.

37 Kept Common-Core Adoption (36 states plus the District of Columbia)

9  Announced a Major Common Core Rewrite or Replacement

4  Never Adopted the Common Core

1  Adopted the Common Core Only in English/Language Arts
