Only 5 states do not have collective bargaining for educators and have deemed it illegal. Those states and their ranking on ACT/SAT scores are as follows:
South Carolina 50th
North Carolina 49th
If you are wondering, Wisconsin, with its collective bargaining for teachers, is ranked 2nd in the country. Let’s keep it that way.
Scott Lemieux adds:
This isn’t to say that the lack of collective bargaining explains these poor outcomes, of course, but it is true that the evidence that breaking teacher’s unions improves educational outcomes is somewhere between “exceptionally weak” and “non-existent.”
Matt Steinglass nods.
