Researchers at Education Next have graded state proficiency standards on an A–F scale since 2005. When the Common Core initiative began in 2009, not a single state had achieved, by today’s standards, an A for having a proficiency bar tightly aligned with NAEP. Six years later, dramatic progress had taken place, with 16 states receiving A grades and 27 others receiving grades in the range of B+ to B- by 2015. The trend continued slightly upwards in 2017, with 4 of the 5 states that had received F grades in 2009 achieving a C+ or higher for their proficiency standards in 2017.
