Here’s Bill Gates, speaking yesterday at the National Conference of State Legislatures:

On expanding the growth of charter schools:

Caps should be lifted for charter school operators who have a proven record of success—and charters should be offered the same per-pupil funding as other public schools. As you know, a relatively small percentage of schools are responsible for a high percentage of the dropouts. We can make dramatic advances by replacing the worst schools with high-performing charters —operated by organizations with a great track record.

On merit pay:

But we don’t identify effective teachers and reward them. We reward teachers for things that do not identify effective teaching—like seniority and master’s degrees. And we don’t reward teachers for the one thing that does identify effective teaching—great performance.

Last year the New York legislature passed a law that says you can’t consider student test scores when you make teacher tenure decisions. That was a strategic win for people who oppose reform – because no real reform will happen until we can evaluate teachers based on their students’ achievement.

I understand the legitimate concern of teachers who point out that, without the right design, teacher measurement systems based on student performance could seem arbitrary.

But without them, we won’t be able to identify our best teachers, reward them, help others learn from them, or deploy them where they’re most needed. We won’t be able to see what curriculum, instructional tools, and teacher training work best.

Any questions?
