Here's the link to what they have to say (or rather what they have me saying, in an excerpt from Chapter 9 "Back to School"):
Why New York City’s high school admissions process only works most of the time
Below are two paragraphs from the excerpt, concerning Neil Dorosin, who worked for the NYC Department of Education at the time, and is now the Johnny Appleseed of school choice as the director of the Institute for Innovation in Public School Choice (IIPSC):
One reason that principals gained confidence was that DOE staffers did a good job communicating to them how the new system would work. Crucial in that effort was Neil Dorosin, the DOE’s director of high school operations. The task of informing everyone about the new algorithm fell to Neil and his colleagues in the Office of Enrollment Services. Among those he had to educate was his ultimate boss, Chancellor Joel Klein.
“One day I got called down to talk to him,” Neil recalls. “He was upset because he had a friend whose child didn’t get into their first-choice school. The friend had a cousin whose child had gotten into the school, and it was their last choice. I had to explain why the system had to function that way” (i.e., to make it safe to list true preferences).
