Changing what happens in the hearts and minds of millions of children—the main charge of any school system—is no simple task. That some do so successfully while others do not is indisputable. So why is it that some school systems consistently perform and improve faster than others?
To find out why some schools succeed where others do not, McKinsey studied 25 of the world’s school systems, including 10 of the top performers. The experience of these top school systems suggest that three things matter most:
Getting the right people to become teachers;
Developing them into effective instructors; and
Ensuring the system is available to deliver the best possible instruction for every child.
