PHOENIX — A suburban school district in metro Phoenix has put off its plan to return its high school to in-person instruction from remote learning starting Tuesday.

Cactus Shadows High School Principal Tony Vining announced late Friday that Cave Creek Unified School District’s sole high school didn’t “have enough staff to safely open and will need to revert to our distance learning model.”

Some Arizona schools have reopened for in-person instruction, but J.O. Combs Unified in San Tan Valley, was thwarted last month because numerous teachers called in sick while voicing concerns about the safety of reopening schools.

The state Department of Health Services on Saturday reported 836 additional confirmed COVID-19 cases with 36 additional deaths, increasing the statewide totals to 205,516 cases and 5,207 deaths.
