NASHVILLE, Tenn.- The issue of collective bargaining rights for teachers was a huge issue on Tennessee's Capitol Hill.
Now the Associated Press has taken a close look, comparing how school systems do with or without collective bargaining rights.
The AP discovered school systems without teachers' collective bargaining rights performed slightly better than those with negotiated contracts. Thirty-eight school districts don't have collective bargaining rights, and the AP found those systems averaged a higher percentage of students who earned proficient or advanced scores.
In May, state lawmakers voted to end collective bargaining rights for teachers.
