Langston prof on school choice and accountability

I've previously called attention to some thoughts on school choice from Matthew Lynch, an education professor at Langston University. I now commend to your attention a new piece by Dr. Lynch over at The Huffington Post. He writes:

Giving parents the freedom to choose their child's school is a movement that strives to improve education at ALL schools through the old-fashioned business concept of competition. Public charter and magnet schools are tuition free, just like public schools, but must make some promises in their contracts in order to stay open. If these schools of choice habitually do not reach their goals, they close. Can the same be said of public schools?
