Harvard studies have shown conclusively that voucher programs are working to increase student learning. This should not come as a surprise.
Children are different from one another.
They do not all thrive in the same school environment. They do best when their parents have the ability to place them in the particular school, public or private, which works best for them. Of course, school choice doesn't just help individual students achieve more. It also helps to improve the effectiveness of the public school systems which voucher or tuition-tax credit receiving students have left behind. Public school educators recognize that when parents have choices it is not enough for public schools to meet minimum standards.
