Embattled DCPS Chancellor Michelle Rhee will turn in her resignation in the morning, effective 31 October 2010, according to multiple news sources. In the interim, her deputy chancellor Kaya Henderson will head the school system, according to our sources at DCPS. Henderson came with Rhee from The New Teacher Project, where she served as Vice President for Strategic Partnerships. If there’s one trait that Rhee lacked, it was the “playing well with others” category that so many of us relied on in Elementary School to keep us up with social promotion, and that seems to be a place where Deputy Chancellor Henderson shined. Before New Teacher Project, she was the Director of Admissions at Teach for America, and she has worked in difficult environments in Memphis, Atlanta and Baltimore amongst other challenging districts.
