COVID-19 Frequently Asked Questions


Face Coverings

Mask wearing as a COVID-19 mitigation measure is optional at BSD schools. This means that mask wearing in both indoor and outdoor settings will be an individual choice for students, staff, families, visitors and volunteers. The Bellevue School District strongly commits to a culture of acceptance, where individual choices will be respected, while we work together to ensure a safe learning environment for all.

While masks are no longer required universally in school settings, there will be situations when the use of well-fitting masks may be temporarily required for individuals by the Washington State Department of Health and/or Public Health Seattle & King County.

Students, children, and staff will have the choice to wear a mask at school and/or at provider settings, with the expectation that others’ choices will be respected. Some may need to wear a mask because they or a member of their household is high risk for severe COVID-19 disease.

Students and staff who are immunocompromised, medically fragile, and/or otherwise high risk for severe disease should consult their health care provider about whether or not to continue wearing well-fitted masks.

Bellevue School District has developed ventilation standards for all buildings in the district.

For ventilation and air circulation we are layering multiple protective strategies including:

  • Increased outside air (ventilation) to each zone to the maximum allowed by the system. Goal will be to exceed rates required by Washington State and ASHRAE. Air is changed over 6.6 – 8.8 times per hour with outside air.
  • Disabled energy saving control functions that would reduce outside air exchange.
  • Ventilation systems and controls that can be monitored and adjusted over the district network.
  • Monitor ventilation systems and controls remotely including carbon dioxide levels which are used as an indicator for fresh air circulation.
  • Operate ventilation systems in occupied mode for one week prior to occupancy.
  • Operate ventilation systems 2 hours before and 2 hours after occupancy.
  • Matching student cohorts to ventilation zones to minimize cross contamination.
  • Using MERV 13 filters that are efficient at capturing airborne viruses and changing them at least once every three months.

What is being done to increase ventilation in classrooms and school hallways?

Systems in all BSD schools have been set to pull in air from outside. District buildings have multiple layers of MERV 8-13 filters in place that are changed every three months. Our ventilation systems are fully commissioned and continuously monitor carbon dioxide levels with sensors as a measure of ventilation.

Do Bellevue schools have air filtration systems in place, such as HEPA or MERV-13?

The district does not have HEPA filters in our HVAC system. We use Tri-Dex 2 ply to 4 ply filters which range from MERV 8-13. Occupied spaces are filtered multiple times by different equipment, such as Heat Pumps, DOAS (Dedicated Outside Air Supply) and Heat Recovery Units. Our filters are changed every three months.

Visitors and Volunteers

Are masks required for visitors and volunteers?  

No, mask wearing is optional for visitors and volunteers at BSD schools. The Bellevue School District strongly commits to a culture of acceptance, where individual choices will be respected, while we work together to ensure a safe learning environment for all.


Are COVID-19 vaccinations required for volunteers?

The COVID-19 state of emergency orders, including the vaccination requirement for K-12 volunteers, ended on October 31, 2022. As a result, proof of vaccination is no longer required for volunteers.
