Of 55 million students enrolled in prekindergarten through 12th grade, about 21.5 million or 39% receive federally subsidized free or reduced-price lunches each school day. In 2013, the school lunch program had an improper payment rate of 15.7%, and the school breakfast program had an improper payment rate of 25.3%. These are among the highest rates of any federal programs, because they require no documentation of parents' income.
