excerpt from Wendy Kopp's email about appointing new CEOs in TFA

We are undertaking these changes to ensure that we have the leadership capacity necessary to tackle our rapidly growing needs and opportunities. Over the last five years, Teach For America has doubled in size, from 5,000 corps members to more than 10,000, from 26 communities to 46. Today we are investing more than ever in growing in scale and diversity, increasing the impact of corps members, and fostering the leadership of alumni. Meanwhile, in the six years since I co-founded Teach For All, it has expanded into a global network of 26 independent organizations that, like Teach For America, are enlisting their nations' most promising future leaders to become lifelong advocates for educational excellence and equity.

Reading this, I don't feel hope or excitement. I feel trepidation about that rapid growth. We're not a perfect model and I don't think getting bigger is going to make us more perfect.
