TALLAHASSEE, Fla. (AP) — An administrative law judge’s ruling has delayed but not stopped a new state teacher evaluation system.

The Florida Education Association is holding a news conference on Tuesday in Tallahassee to discuss its continuing fight against the proposal.

The statewide teachers union won the first round as a result of the administrative hearing decision, but the State Board of Education is redrafting a proposed rule.

The judge held the initial draft violated rule-making procedures. The revised version is expected to be ready for board approval in early 2013.

The rule is designed to implement a law passed last year that requires evaluation plans to include what’s known as a value-added measure based on student test results.

Evaluations are used to determine which teachers are retained and which receive merit pay.
