Current laws make real educational innovation illegal. How? First, they require that all students attend school. And then they define what a school has to do so narrowly that any meaningful innovation impossible.
For example, the school day is set at 170 days (even for private schools). That means that a school that manages to teach more efficiently, and teach the material in 160 days, or 150 days, is not rewarded. (That's one reason that most school curricula are so full of unnecessary filler.) That also means that schools cannot use vacation time as an incentive. (E.g.: "As soon as you have mastered algebra, you can go on break but not until then.").
As another example, all teachers need to be college graduates. So if you want to hire Bill Gates or Mark Zuckerberg to teach math or computer science at your PRIVATE school, that would be illegal in Maryland.
The individual mandate in schooling is the root cause of this problem. If there were no requirement, then parents could choose any educational service they want: learning centers, tutors, etc. (you know, the people whose job it is to correct the mistakes made in traditional schools).
