The federal government's role in financing school construction and renovation continues to be an issue in the 109th Congress, although school construction has generally been considered a state and local responsibility. According to the National Center for Education Statistics (NCES), the unmet need for school construction and renovation is estimated to be $127 billion. NCES indicates that three-quarters of the nation's schools report needing funds to bring their buildings into a "good overall condition." Indirect federal support for school construction is currently provided by exempting the interest on state and local governmental bonds from federal income taxes, as well as other tax code provisions. In the wake of Hurricane Katrina, an estimated 400 schools need to be rebuilt in Louisiana and Mississippi.
