One of the things that we're all struggling with is how to judge the quality of the value-added experience of an educational course or year. I don't think it's impossible to do that, but it's difficult.

But you take a four-year state college, with a broader range of admission, and what happens during those four years may be an even greater value-added educational experience. I don't know.

Lets take flight simulation as an example. If youre trying to train a pilot, you can simulate almost the whole course. You dont have to get in an airplane until late in the process.

The need for a college education is even more important now than it was before, but I think that the increased costs are a very severe obstacle to access. It is an American dream, and I think that one of our challenges is to find a way to make that available.

You can take a school like the University of Colorado, with a selective admission standard. It has a better caliber student going in, so you ought to have a better caliber coming out.

Common standards ensure that every child across the country is getting the best possible education, no matter where a child lives or what their background is. The common standards will provide an accessible roadmap for schools, teachers, parents and students, with clear and realistic goals.
