TAVARES, Fla. -

Lake County School Board members voted Monday night to spend thousands to investigate alleged class-size violations.

The board approved spending up to $20,000 to bring in an a Tallahassee accounting firm after it was found six schools under-reported the number of students in each class.

State law only allows between 18-25 students in every class depending on the grade, but after a teacher complained, the state found Mount Dora High, Lake Minneola High, Sawgrass Bay Elementary, Grassy Lake Elementary, Sorrento Elementary, and Tavares Elementary had under-reported their numbers.

Some teachers said they were pressured into faking the number of students in their classes to meet state law.

The school board hopes the independent investigation will answer several unanswered questions about how the state was given wrong information.

Superintendent Susan Moxley has said in the past principals could be punished if it was found they acted improperly.

The independent review is expected to be finished by the end of May.
