It looks like several Florida counties have been hijacked by creationists touting the "teach the controversy" mantra. An Op-Ed article suggested that 12 Florida counties have passed such measures, but at this time, only 6 have been identified.
However, a student from Martin County's Jensen Beach High School has informed me that his teachers aren't allowed to teach evolution because "evolution [is] not 100% true". He also said that this isn't just his school but the district at large as a result of actions by the school board. Neither of the websites outlines any position on science education.
UPDATE: I've Emailed school officials concerning this policy Sunday, but have yet to receive any sort of response. Information has been passed onto the NCSE. Perhaps they'll get a better response.
