That’s the conclusion of a new study by the National Council on Teacher Quality, a Washington-based think tank that advocates for measuring teacher effectiveness through objective data like test scores. It studied evidence of the outcomes of teacher-evaluation reform in Denver; the Dallas Independent school district; the District of Columbia; Newark, N.J.; New Mexico; and Tennessee.
Teacher ratings in all of the sites improved, it found, and highly effective teachers were likely to stay, while low-rated teachers left.
