Problems also arise in U.S. public schools concerning the teaching and display of religious issues. In various counties, school choice and school vouchers have been put forward as solutions to accommodate variety in beliefs and freedom of religion, by allowing individual school boards to choose between a secular, religious or multi-faith vocation, and allowing parents free choice among these schools. Critics of American voucher programs claim that they take funds away from public schools, and that the amount of funds given by vouchers is not enough to help many middle and working-class parents.
