Warren County will join with three other Middle Tennessee school systems looking to split a grant for $20 million.The grant, being offered by the U.S. Department of Education in its Race to the Top program, would amount to getting $20 million over five years with no strings attached, Director of Schools Bobby Cox told the Warren County Board of Education in asking approval to join the four-county effort.“The thing about this is there are no matching funds we would have to put up,” Cox told the School Board, noting if selected to receive the grant, the four school systems would have the money in a common fund for use in their Race to the Top education initiative.The school systems which Warren County will join in asking for the grant will be Lincoln and Lawrence counties, along with Tullahoma.“I think this is an excellent opportunity,” Cox said. “We really have nothing to lose and potentially a lot to gain.”The School Board unanimously approved Warren County entering into the four-system alliance.
