I am often asked my views about what the federal government should do to improve education.

The one thing it should not do is to foist unproven ideas on the schools across the nation.

Whatever policies it supports should be amply supported by evidence and experience, such as class size reduction and early childhood education.

The more I travel, the more I recognize the enormous diversity of this great nation.

It is the height of arrogance to believe that there is one set of reforms that will work in every school in every community, be it urban, suburban, rural, or something in-between.

No one person in this nation is wise enough to tell everyone else how to teach and how to evaluate teachers and how to run schools.

No district has all the answers.

There are specific roles that the federal government should play. In this interview, I describe what I think is most important.
