Changing from No Child Left Behind to Common Core will benefit teachers and students, according to incoming Director of Schools Bobby Cox, who is serving on the board which will implement the new statewide system.“We’ve always said if something would get taken off the plate we could finally get something done. Well, Common Core does this,” Cox told the School Board during its recent meeting. “Common Core takes redundancy off the plate and allows teachers to be more in-depth.”Tennessee was among the states which were allowed to opt out of No Child Left Behind due to what was found to be nearly impossible goals set by the educational initiative.“These goals are all attainable,” Cox said.
