NAPLES, Fla. (AP) - The Collier County School District in southwest Florida is planning to join a lawsuit challenging penalties for not meeting the state's class size requirements.

Officials have agreed to join the Florida School Boards Association and other districts in the suit, which is expected to be filed in Tallahassee by early September.

Penalties for not meeting the stricter class size requirements this fall could reach $351 million statewide. Voters will decide in November whether to keep class sizes at the current limits.

Fines for the Collier County district would be $2,500 to $3,500

per student.
