Quarantine happens when a person has been identified as a close contact of someone who has COVID-19. Quarantine means the person should stay at home away from others for 5 days.

Students and staff may return to school when they:

  • Complete 5 days of quarantine from the date of the close contact; AND
  • Continue to NOT have symptoms

Students and staff who are identified as close contacts may be exempt from quarantine if they:

  • Are up to date on vaccinations, including boosters, per CDC criteria; AND
  • Are able to wear a face mask consistently and correctly; AND
  • Are asymptomatic


Isolation happens when a person tests positive for COVID-19. Isolation for students means the student should stay at home away from others (even others in their home) for 10 days. (CDC guidance states that a reduced isolation timeframe may only be implemented for students with consistent physical distancing protocols in place at all times, including during meals. Since we cannot maintain distancing consistently in school, per CDC, APS will continue to require 10 days isolation for students with COVID-19. )

Students may return to school when they:

  • Complete 10 days of isolation from symptom onset or since testing positive (day test administered), whichever is first; AND
  • Be fever free for at least 24 hours without fever-reducing medication.

Staff with diagnosed with COVID-19 will be required to isolate for 5 days and wear a mask at all times for an additional 5 days, per CDC guidelines.

Other Definitions

Contact Tracing is the process of identifying individuals who are considered close contacts to someone with a positive or probable case of COVID-19. During the investigation, the school administration and school Health Clinic will confirm the report of a positive diagnosis, identify students and employees who meet the close contact definition, and contact the close contacts to inform them of their exposure.

Information on instruction during quarantine

Close Contact

A close contact is identified as a student within the classroom setting that meets any of the following criteria:

  • Within 3 feet of another masked student
  • Within 6 feet of another student who has a mask exemption
  • Within 6 feet of an adult regardless of mask usage
  • Within 6 feet of another student outside the classroom regardless of mask usage

Positive Case

A positive case is an individual who has been instructed by a health care provider that they have COVID-19 or has received laboratory results indicating that they have tested positive for COVID-19 (regardless of vaccination status).

Probable Case

A probable case is an individual who has had a close contact exposure, regardless of vaccination status, and has developed symptoms within the 14 days of that exposure.
