Education

33 school districts provide public education in the Phoenix area. This is a legacy of numerous annexations over the years; many of the school districts existed before their territories became part of Phoenix.

There are 21 elementary school districts, which have over 215 elementary schools, paired with four high school districts with 31 high schools serving Phoenix. Three of the high school districts (Glendale Union, Tempe Union, and Tolleson Union) only partially serve Phoenix. With over 27,000 students, and spread over 220 square miles (570 km), Phoenix Union High School District is one of the largest high school districts in the country, containing 16 schools and nearly 3,000 employees. In addition, there are four unified districts, which cover grades K–12, which add an additional 58 elementary schools and four high schools to Phoenix's educational system. Of those four, only the Paradise Valley district completely serves Phoenix. Phoenix is also served by a growing number of charter schools, with well over 100 operating in the city.
