| Good teachers matter. This may seem

teacher can cram one-and-a-half grades’ worth of learning into a single year,
while laggards are lucky to accomplish half that much. Yet, while we know now that better teachers are critical, flaws in the way that administrators select and retain them mean that schools don’t always hire the best. Failing to recognize the qualities that make teachers truly effective and to construct incentives to attract and retain more of these top performers has serious consequences.
