TALLAHASSEE, Fla. -- Florida's State Board of Education is considering making last-minute changes to the formula used to calculate annual school grades.
The panel is scheduled to vote Tuesday on a proposal from Education Commissioner Tony Bennett.
Each year the state hands out A-to-F grades that are used to reward top schools and sanction those that get failing marks.
But Bennett on Friday recommended a "temporary rule" that would limit a school grade from dropping more than one letter at a time.
The commissioner is responding to worries from school superintendents that recent changes to the grading system would create a large drop in the grades that are widely used by parents to evaluate schools.
The grades are based primarily on student performance on a series of high-stakes tests.
