Merit pay for teachers based on genuine, verifiable student learning would be a good thing. But the bill the Legislature finalized early Friday morning has too many holes in it, takes away local control and doesn't pay for the changes it orders.
Gov. Crist has said he might veto the bill, and that's exactly what he should do.
The bill requires local school districts to hire, fire and pay teachers according to how well students do on end-of-course exams in all subjects. But those tests don't exist yet. So how can teachers and students know they'll be valid when they go into effect in 2014? The Legislature says the state Department of Education will take care of the details.
That would be more reassuring if the state had a better track record on the FCAT. For a decade Florida has corrupted an otherwise useful test by putting way too much weight on it. Entire schools and districts are graded on a high-stakes test that doesn't even cover most subjects.
