Chandler USD has reported 24 COVID-19 cases across its 45 schools as of Nov. 2, according to data from the district.

Chandler High School, Perry High School and Hamilton High School reported three cases each, meaning all three school sites have an "outbreak," which is defined by the Maricopa County Department of Public Health as a school site with more than two confirmed cases. Patterson Elementary School, Payne Junior High School and Rice Elementary School all reported two cases each.

Chandler USD spokesperson Terry Locke said the district is being careful not to provide identifiable information on individuals. Locke said people have had to quarantine as a result of the cases at the high school campuses.

Chandler USD junior high and high schools went back to in-person learning Oct. 13 after spending the first quarter learning remotely. Elementary school students in the district returned in late September in a staggered approach. Students and staff are required to wear masks while on campus, and social distancing and enhanced sanitizing protocols have been put in place districtwide.

"It’s important that students, staff and parents collaborate to ensure safety," Superintendent Camille Casteel said. "This includes staying home when not feeling well, reporting cases to the schools and employing safety precautions, including social distancing, wearing masks and washing hands properly."

The Maricopa County Department of Public Health reported Nov. 2 that 37 schools in the county have active outbreaks. The county also reported 203 total cases tied to schools: 152 in students and 51 in staff.

Here is a breakdown of cases across Chandler USD.

As COVID-19 cases continue to rise across the state, the Arizona Department of Health Services amended the criteria for reopening Arizona schools. In a blog post, the head of the ADHS said the health agency determined that all three transmission benchmarks should be in the "substantial" category before a county moves into the "substantial" category on the schools dashboard with a recommendation that districts and charter schools begin planning for virtual learning. As of Oct. 29, the state's dashboard for schools suggested Maricopa County schools should be taking a hybrid approach—with two out of the three benchmarks showing increases. The statewide dashboard does not look at the past two weeks due to potential lags in data, according to ADHS.
