But we can reverse course. In the next 10 years, over half of the nation’s nearly 3.2 million public school teachers will become eligible for retirement. Who will replace them? How do we attract and keep the best minds in the profession?

People talk about accountability, measurements, tenure, test scores and pay for performance. These questions are worthy of debate, but are secondary to recruiting and training teachers and treating them fairly. There is no silver bullet that will fix every last school in America, but until we solve the problem of teacher turnover, we don’t have a chance.

Can we do better? Can we generate “A Plan”? Of course.

The consulting firm McKinsey recently examined how we might attract and retain a talented teaching force. The study compared the treatment of teachers here and in the three countries that perform best on standardized tests: Finland, Singapore and South Korea.

Turns out these countries have an entirely different approach to the profession. First, the governments in these countries recruit top graduates to the profession. (We don’t.) In Finland and Singapore they pay for training. (We don’t.) In terms of purchasing power, South Korea pays teachers on average 250 percent of what we do.

And most of all, they trust their teachers. They are rightly seen as the solution, not the problem, and when improvement is needed, the school receives support and development, not punishment. Accordingly, turnover in these countries is startlingly low: In South Korea, it’s 1 percent per year. In Finland, it’s 2 percent. In Singapore, 3 percent.

McKinsey polled 900 top-tier American college students and found that 68 percent would consider teaching if salaries started at $65,000 and rose to a minimum of $150,000. Could we do this? If we’re committed to “winning the future,” we should. If any administration is capable of tackling this, it’s the current one. President Obama and Education Secretary Arne Duncan understand the centrality of teachers and have said that improving our education system begins and ends with great teachers. But world-class education costs money.

For those who say, “How do we pay for this?” — well, how are we paying for three concurrent wars? How did we pay for the interstate highway system? Or the bailout of the savings and loans in 1989 and that of the investment banks in 2008? How did we pay for the equally ambitious project of sending Americans to the moon? We had the vision and we had the will and we found a way.
