U.S. presidential candidates are talking about the problem of high costs in higher education. From 2002 until 2012, tuition increased by around 39 percent, on average, among public or government-funded universities. Among private universities, it rose around 16 percent on average. The presidential candidates agree that the cost of education is a problem, but they disagree about what to do about it. The two main Democratic contenders are Hillary Clinton and Bernie Sanders. They both have plans for addressing the high cost of education. Hillary Clinton's plan is called the New College Compact. The plan calls for giving grants to states. Grants are money given to states from the federal government. They help boost other financial aid to students, and help pay for living costs and tuition. Under Clinton's plan, community colleges would be tuition-free.
