Almost half of New York City's 1200 principals have been on the job for less than three years, and principal retirements are expected to grow in the next few years. To help novice principals learn the ropes, the New York City school system offers an innovative 10-day summer seminar, seminars during the school year, and 40 veteran principals who have agreed to be available for calls and visits with new principals. This program is led by ace public-school educator Mary Butz. See "As Veterans Retire, New Principals Get Summer School," by Anemona Hartocolis, The New York Times, August 21, 2002.
