This is a devastating problem, is, the longer our children are in school, the worse they do. Year after year after year, our children in America are falling further behind. Our 3- and 4-year-olds enter kindergarten OK, and they fall further and further behind. Each year, children in other countries are learning more than children in this country. And so the gap between American student performance in Singapore and Finland and South Korea and Canada and these other countries, the gap widens year after year after year.

We need to invest in very different ways. Get the students the support they need, get them the best principals, get them the great teachers, and I promise you those students would do extraordinarily well. I have seen it all my life.

To encourage more top-caliber students to choose teaching, teachers should be paid a lot more, with starting salaries more in the range of $60,000 and potential earnings of as much as $150,000.

What you see around the world is that poverty is not destiny. In other countries, much more systemically, student after student, school after school, year after year, educate poor and disadvantaged young people. And, so, anyone who says that you can't overcome these battles is a huge part of the problem.

The jobs of the future, as you know so well, are knowledge-based. You need college-educated folks to do this work. And so the consequences for our country are absolutely devastating if we don't start to behave in very different ways.

Wherever you find something extraordinary, you’ll find the fingerprints of a great teacher.

Teachers say their schools of education did not adequately prepare them for the classroom. They would have welcomed more mentoring and feedback in their early years.
