If President Obama is really serious about education reform, he ought to consider putting D.C. school Chancellor Michelle Rhee in charge of the effort.

This lady is not afraid of a major challenge, as evidenced by her latest brawl with the AFT.

Rhee is courageously targeting the sacred cow of teachers unions – tenure. It’s the system that pretty much guarantees a teacher a job for life, if he or she can make it through the first few years. It doesn’t matter if they go on to become good, mediocre or bad teachers. With tenure, they are pretty much protected until retirement.

But Rhee understands that such a system can no longer be tolerated in Washington D.C. schools, which have a dropout rate of nearly 40 percent. She knows that the school district must have the power to sift through the teaching staff, keep the good ones, work with the middle-of-the-roaders, and get rid of the bad apples.

She also understands that it has to work both ways. She’s willing to develop a compensation system that would offer teachers much higher pay, in exchange for the union abandoning, or at least reforming, the concept of tenure.

We have no problem with that at all. Teachers are extremely important in our society, and good ones deserve to be paid like the vital professionals they are. While schools throughout the nation are struggling with their budgets, we’re sure that most would be happy to find the money to increase teacher salaries, if only they had to power to pick and choose what teachers to keep.

Rhee has already backed up her words with action. Earlier this year she hired more than 900 new teachers for the district, then weeks later laid off 266, citing budget constraints. But the layoffs weren’t limited to the recent hires. She made cuts based on ability, not seniority, a move that drove the AFT into court to challenge Rhee’s decision.

According to the Wall Street Journal, AFT President Randi Weingarten said Rhee “has so poisoned the environment that I am not sure that we can ever get back to a good situation here.”

That’s where you’re dead wrong, Ms. Weingarten. Rhee’s “poison” is exactly the proper remedy to get D.C. schools back on track, and restore public confidence in the district.

Families aren’t interested in a teacher’s longevity, Ms. Weingarten. They want to know if that teacher can manage to help their children reach their potential, and if not, then he or she no longer belongs in a classroom.
