Michelle Rhee has worked valiantly to improve the District of Columbia’s school system, but her latest decision to drop support of the most rigorous teacher training, National Board Certification, and instead support “The Skillful Teacher” program shows that she is choosing formula over reflection.

According to a January 5 article in The Washington Post, Rhee plans to further weed out weak D.C. teachers and subject the remaining to “professional growth” based on “The Skillful Teacher” model created in 1987 by Jon Saphier and Robert Gower.
