ORLANDO, Fla. (AP) - Five of the state's largest school districts are questioning the latest results of the FloridaComprehensive Assessment Test.

Superintendents of Broward, Miami-Dade, Hillsborough, Duval and Leon county schools sent a letter Monday to State Education Commissioner Eric Smith. They want the state to delay calculating annual school grades based on the test scores and for a committee of experts to review the data.

Smith said last month that test results were delayed this year because of problems in matching databases, not the quality of scoring. He said he was confident the scores were accurate.

No central Florida county was included in the letter, but Seminole County spokesman Regina Klaers says the district saw "some anomalies."
