"What this graph helps illustrate is that we have a lot more commonality in standards and assessments than we did five years ago. We never got to perfect commonality, and, in fact, the trend is slowly moving in the other direction. If other states follow Georgia’s lead and go their own way on assessments, that red bar will continue to creep up. But, if states switch between consortia, join ACT’s Aspire, or work with another state, the number of assessments will stay the same. No state has officially dropped out of the Common Core standards yet, but that blue bar could rise over time as well."
