TALLAHASSEE, Fla. (AP) - State officials suspect possible cheating on nearly 7,000 Florida Comprehensive Assessment Tests.
    
The Department of Education on Friday confirmed that 14 of Florida's 67 county school districts have been asked to investigate.
    
A security company contracted by the state found a highly improbable number of common answers or excessive erasures on 6,697 of the 4 million FCAT exams taken this year.
    
Those exams were invalidated, but school districts can appeal.
    
The counties where suspected exams were found include Miami-Dade, Broward, Palm Beach, Hillsborough and Orange.
    
The others are Duval, Flagler, Polk, Lee, Leon, Manatee, Seminole, Jefferson and Gadsden.
    
FCAT reading, math, science and writing scores are used to grade schools. Students must pass the 10th grade FCAT to graduate and the 3rd grade reading test to be promoted.
