WASHINGTON ( CNN ) -- Secretary of Education Arne Duncan is expected to push for reforms in how teachers are taught when he speaks at Teachers College at Columbia University in New York on Thursday . Education Secretary Arne Duncan is expected to say colleges profit from education schools but reinvest little . According to advanced quotes released by the U.S. Department of Education , he will say that `` schools , colleges and departments of education are doing a mediocre job of preparing teachers for the realities of the 21st-century classroom . '' He will call for a `` revolutionary '' change in teacher preparation programs . Duncan estimates that about 200,000 new teachers will enter U.S. school systems annually . `` Schools of education have been renowned for being cash cows for universities , '' Duncan will say , according to his released remarks . `` The large enrollment in education schools and their relatively low overhead have made them profit centers . '' Duncan will say that universities divert the profits from education schools to other departments while doing little to invest in educational research and clinical training . Duncan has focused on teacher accountability since he took office in January . Under the criteria to receive stimulus money under the Department of Education 's Race to the Top program , states that link student achievement data to teacher evaluations will be rewarded . Several states , including California , have removed laws that made such links illegal .
