National Education Association:
Points were tallied and converted into letter grades using a total of 100 potential points and a traditional A – F scale. Only six state statutes garnered enough points to avoid an “F,” and all of those were “D” grades except for Maryland (“B-“) and Tennessee (“C-“). To better distinguish among the statutes, the large majority of which simply failed to meet NEA’s standards, NEA divided states into sub-groups according to their overall score.2 By referring to these sub-group ratings, it is possible to better distinguish between, for exam- ple, the District of Columbia (“worst” with 20 out of 100 points) and Arkansas (“poor” with 59 out of 100 points), both of which received failing grades. NEA’s comprehensive review of all charter statutes in the country concluded on November 9, 2018. This Report reflects only laws in existence as of that date.
