Sara Stevenson is the librarian at the O. Henry Middle School in Austin, Texas.

She is an activist for public education.

She is tireless.

She scans the Internet, reads voraciously, and writes letters to the editor to set people straight about the facts.

If every teacher and principal and superintendent and parent and librarian and guidance counselor and school psychologist did what Sara Stevenson does regularly, the national conversation would change.

The American public would be better informed.

The policymakers would change their tune.

The hedge fund managers would go back to dabbling in polo ponies and yachts.

And we could all concentrate on doing what is necessary to make our schools and our society better for all students.

Watch for her letters to the editor in the Wall Street Journal and other national publications.
