Choice doesn't guarantee success. There are many restaurants to choose from in NYC. This doesn't mean all restaurants are good. Same goes for charters. This doesn't mean restaurant choice is bad. But if choice is to be used for schools, maybe we need a "health department" to shut down the bottom 10%, and spread "best practices" from the top 10%. And make sure the results are presented to the parents in a user-friendly manner so they can make good choices.
Accountability doesn't guarantee performance. You can grade restaurants as Los Angeles or Zagat do, but this doesn't make all restaurants clean or worth visiting. But it helps the consumer make better choices, and helps identify those that perform well, and give those under-performers a guide to which head chefs they may want to hire, or which restaurants they may want to visit to steal good ideas....
