Over time, the typical career span of superintendents (in that position only) has been about 15 to 20 years. In large measure, this relatively short period is explained by the fact most superintendents enter the position in mid-career. Data collected and analyzed by AASA in 2010 revealed nearly two-thirds of superintendents (62 percent) first entered the position when they were 41 to 55 years old. Outside this age range, novices were twice as likely to be younger than 41 than older than 55. Only 8 percent of superintendents first entered the position after age 55.
