Turnover at the NYC Dept of Education

One lesson we've learned from working on school choice in NYC and Boston is that the educational bureaucracies have enough turnover that it is hard to keep in close contact. In each place, the people with whom we worked most closely have moved on to other jobs. Now in NYC the last of the higher level leaders who were involved in revamping the high school choice process are leaving as well:
Elizabeth Sciabarra is leaving as head of student enrollment, and Joel Klein is leaving as chancellor (Publishing exec named new NYC schools chancellor)

Update: New York Schools Chancellor Ends 8-Year Run has more on Klein's tenure.
