It’s odd, but the remarkable resurgence of D.C. public schools over the last two decades could have been predicted from the 1992 Teach for America classes in Baltimore and Washington. Those classes included three players who would shape the future of District of Columbia schools: Michelle Rhee (future D.C. chancellor), Kaya Henderson (Rhee’s successor) and, perhaps most importantly, Susan Schaeffler, 55, who is retiring after 25 years as the founder of the KIPP DC Public Schools charter network.
