Out of these 10 states, only one (Virginia) has an average rank above the median, while four are in the bottom 10, and seven are in the bottom 15.

In contrast, nine of the 10 states with the highest average ranks are high coverage states, including Massachusetts, which has the highest average score on all four tests.
If anything, it seems that the presence of teacher contracts in a state has a positive effect on achievement.
