The National Board for Professional Teaching Standards, Inc. has been funded, in part, with grants from the U.S. Department of Education and the National Science Foundation. Through September 2009, NBPTS has been appropriated federal funds of $188 million, of which $168.7 million was expended. Such amount represents approximately 30 percent of the National Board's total cumulative costs. Approximately $398.1 million (70 percent) of the National Board's costs were financed by non-federal sources.
