ALLAHASSEE, 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.
