In June, Arizona’s Republican-led Legislature passed a state budget package that included a controversial provision prohibiting school districts from requiring masks. Gov. Doug Ducey, who for months had emphasized “personal responsibility” over pandemic-related mandates, signed off.

But nearly three months later, details surrounding the timing, implementation and enforcement of the law remain unclear. And as state and local officials argue over the ban’s merit, COVID-19 continues to spread. 

Since students returned to in-person learning in August, districts have reported more than 2,000 confirmed COVID-19 cases and required thousands of students to quarantine.

A clear picture of school-based COVID-19 outbreaks has so far proven elusive, given the rapidly evolving situation and the fact that neither the Arizona Department of Health nor the Arizona Department of Education publishes a dashboard of statewide COVID cases in schools. Though some counties and school districts are monitoring outbreaks at the local level, there is no centralized tracking system. 

With your help, AZCIR has set out to provide a more comprehensive, regularly updated picture of where students and staff are contracting COVID-19 across Arizona—and how schools are responding.

When does the state’s ban on school mask requirements take effect?

Though legislators stipulated the ban would apply retroactively, they did not have the two-thirds majority required to circumvent the typical 90-day waiting period. On Aug. 16, a Maricopa County Superior Court judge ruled the ban therefore would not take effect until Sept. 29.

How aggressively will the state enforce the ban? 

Twenty-six Republican lawmakers have asked Ducey to withhold federal funding from and initiate legal action against any district that ignores the ban. They also asked the governor to authorize Empowerment Scholarship Accounts, or school vouchers, for all students “trapped” in those districts.

In a public letter dated Aug. 11, they contended a “resounding message must be delivered to any local government or subdivision of the state considering defying state law” that “lawlessness will not be tolerated.”

Do students and staff have to quarantine if they are exposed to COVID in schools? 

That depends; county health departments in Arizona can issue quarantine guidance. 

Maricopa County Department of Public Health, for example, recently began requiring students and staff who came in “close contact” of a known COVID-19 case to quarantine. The county has provided a form letter school officials can use that says those who are not fully vaccinated or have not tested positive for COVID-19 in the last 90 days are to quarantine (stay) at home for up to 10 days.”

Do schools and child care establishments have to report COVID-19 outbreaks to their local health departments? 

Yes, within 24 hours. 

Which counties have online dashboards or reports tracking COVID in schools? 

Coconino County publishes a COVID-19 school update every Friday that summarizes case rate and percent positivity at district level. 

Maricopa County tracks schools with active and resolved outbreaks in a dashboard, but does not differentiate by school or district. Some districts maintain their own dashboards online.

Pima County tracks cases by school district. This tracker links to some school districts in the county that have their own dashboards, where they further break down case numbers by school. 

Pinal County has a dashboard that shows cumulative cases by the area each school district covers, but not cases specifically from schools. Some school districts maintain their own dashboards online.

While other counties do not have dashboards, some school districts have made their own, such as Kingman Unified School District #20 in Mohave County.
