MIAMI -- U.S. Education Secretary Arne Duncan is questioning why the Florida Legislature passed a law requiring districts to continue tutoring services that haven't proven effective.
    
Florida was one of nearly a dozen states that received a waiver from the federal No Child Left Behind law. That waiver included lifting a requirement for the state to set aside 20 percent of Title I funds for special tutoring services.
    
In remarks before the Florida Council of 100 in Washington on Thursday, Duncan noted a new study showing the mandated tutoring had no impact on performance. He said a cottage industry of tutoring companies has emerged around the mandate.
    
The Florida Legislature passed a law that will take effect in July requiring 15 percent of Title I funds be used for supplemental education services.
