ESS was founded 18 years ago with the vision of providing administrative relief to school districts and professional working opportunities to qualified educators. Beginning in 2000 with just 17 partner districts and 150 substitute employees, the ESS program quickly became the premier solution for school districts and substitutes nationwide. We are now partnered with more than 650 districts in 21 states, serving 2,500,000 students daily and filling 40 different types of substitute and permanent positions in 13,000 assignments each day. As the largest education-exclusive staffing provider in the country, our history and depth of service position us to provide the most effective solutions to all school districts.
