"Employment of education administrators is expected to grow by about 8 percent between 2008 and 2018, which is about as fast as the average for all occupations. Expected growth is primarily the result of growth in enrollments of school-aged children. In May 2008, elementary and secondary school administrators had median annual wages of $83,880; and postsecondary school administrators had median annual wages of $80,670. Salaries of education administrators depend on several factors, including the location and enrollment level of the school or school district."
