The Lewisville ISD board of trustees approved to renew its contract with ESS South Central, which is a third-party company that supplies the district with substitutes, during a Dec. 12 meeting.
ESS was initially hired by the district Dec. 13, 2021, to provide the district with substitute teachers. This was a shift from the district providing the substitutes.
The substitute fill rate at the district for the 2019-20 school year was 86.3%, and the 2020-21 school year fill rate was 75.4%, according to district data. The 2021-22 school year fill rate was 57.1%. Since the inception of the contract, the fill rate average is 71%.
The goal is to increase the district’s substitute fill rate, resolve equity gaps among campuses, and retain local control of hiring requirements and pay rates, according to the agenda.
