A reader sent a blog post from Arizona, where the Great Hearts charter school chain is based.

This is the charter that Tennessee Commissioner Kevin Huffman wants to bring to Nashville, over the opposition of the local school board.

It is expensive to go to Great Hearts. The school asks parents for an upfront contribution (voluntary, of course), of $1200-1500. Then there are extra costs for books, supplies, physical education.

But it is still less costly than paying for private school tuition. So it is entirely understandable that white, affluent parents would want to bring Great Hearts to their neighborhood in Nashville.
