TALLAHASSEE, Fla. (AP) - Three hotly debated education bills are heading for what appears to be final passage in the Florida House.

The chamber begins floor action Wednesday on a proposed state constitutional amendment (SJR 2) that would loosen class size limits and a bill (SB 6) that would make it easier to fire teachers and link their pay to student test scores.

Another bill (SB 2126) on the calendar would expand a program that provides private school vouchers to low income students.

Votes are expected Wednesday or Thursday.

All three measures are backed by most Republicans in the GOP-controlled Legislature. The Florida Senate already has passed all three over opposition from the statewide teachers union and most Democrats.
