The Star-Ledger gets behind merit pay for teachers in today’s editorial, arguing that the typical union denunciation — that a differentiated pay system would harm collegiality — is unpersuasive.

It is not, we suspect, the fact that some teachers will get more money that makes so many in education nervous about merit pay but the prospect that all teachers will be evaluated. Yet teachers routinely administer tests and score and judge their students.

Teachers must begin to ac cept the same for themselves.

Is it our imagination, or is there some momentum behind this movement?
