I am an historian.
And what I love about being an historian is it gives you perspective.
Today, I'd like to bring that perspective to education in the United States.
About the only thing people can agree on is that the most strategic time for a child to start learning is early.
Over 50 years ago, there was a watershed moment in early education in the US called "Head Start."Now, historians love watersheds because it makes it so easy to talk about what came before and what's happened since.
Before Head Start, basically nothing.
With Head Start, we began to get our nation's most at-risk children ready for school.
Since Head Start, we've made strides, but there are still 2.2 million children in the US without access to early learning, or more than half of the four-year-olds in the country.
That's a problem.
But the bigger problem is what we know happens to those children.
