Health and Safety

The Coronavirus
and Covid-19

We invite you to learn more about us and join our program for an exceptionally safe and rewarding learning and development experience for your child and your family.

Our health and safety practices throughout the pandemic resulted in no Covid-19 transmissions within our program in the first 2.5 years. As a result, our program has continuously been able to offer our rich, award winning services that derive from children’s inclinations, interests, fascinations, and family cultural influences, and it is conducted in a medically safe, educationally rich, and emotionally supportive and stimulating environment.

C5 Children’s School is fortunate to have many seasoned, highly skilled professionals who take an unfailingly positive and confident approach to addressing issues that arise in daily work and in special circumstances, such as during the evolving Coronavirus pandemic.

We work skillfully and respectfully with our enrolled and alumni families and with our building management and local and state government officials to address the relevant science, evolving guidelines, and the health directives that are issued and available.

Then, we take great satisfaction in creating the safest and highest quality environments for children, families, staff, and the interconnected surrounding community. All of our staff are vaccinated and have current booster shots.

Much of our approach to the virus and our strategies for mitigating it are serving as a model for other educational programs. We enjoy our work, and we enjoy sharing to improve the conditions for children everywhere.

You are welcome to contact us for details beyond the information that is provided here.

We have developed and maintained a comprehensive, evolving Coronavirus Health & Safety Plan for each of our centers. The plans are very similar. We also plan ahead for emerging issues in close coordination with these area resources:

  • C5’s Caterer, Chefables
  • The San Francisco Department of Public Health (SFDPH) Childcare Team
  • First 5 of San Francisco
  • The City’s Child Care Planning and Advisory Council
  • The City’s Children’s Council
  • The City’s Department of Early Care

We keep pace with daily reports of virus levels in the community and the emergence and spread of variants and their impact on people and programs within nearby communities, around the state, and across the nation.

Our investigations have kept pace with the latest scientific findings, related product and equipment producers specifications, local and state health department perspectives, and government announcements and directives. We researched the latest HVAC and quality air flow requirements related to the Coronavirus and conducted two site visits with a consulting architect from the Low-Income Investment Fund (LIIF) organization and a site visit with the environmental engineer from the San Francisco Department of Public Health.

We closely follow any emerging San Francisco Department of Public Health’s directives related to early childhood. 

We work in concert with the State of California directives regarding program operating, including handling cases that may occur within our enrolled families, staff, and children attending our program.

We keep the centers clean and sanitary according to the latest guidelines. Our designated kitchen and housekeeping staff also continue to clean high touch areas and elements in the main traffic areas within the centers throughout the school day.

We practice safe social, physical, and structural distancing and wear masks at all times indoors. We know that the research has shown that the primary transfer of the Coronavirus is by air and tiny aerosol droplets that carry the particles that can travel well over 12 feet, hang in the air, and move through spaces with air currents in tidal pools and pathways of air flow.

We operate the centers primarily with only staff and children, and parents and adult family members who are fully vaccinated and boosted. Vendors stop at the front door to transfer goods, materials, and other items into the centers.

During School: Parents can be in contact with the school in a wide variety of ways, including by phone to the reception desk, Office Manager, Center Director, their child’s classroom’s cell phone, by text, email, FaceTime, BrightWheel computer app, video conference, and our highly interactive private, secure website posts and forums.

 Information Sharing: Parents voluntarily share their travel plans, general virus-related health, and ongoing information about how their child is doing at home, including socially, emotionally, physically, and developmentally in line with the in-school curriculum and other activities. Parents follow and support the organic child-centered, flexible Weekly Plans based on the children’s interests and the Daily Stories that we present with photos and text of what actually happens in the classrooms each day.


All children, parents, staff, and specially authorized guests who enter the center clean their hands and shoes before participating in the classroom activities.

We have high powered IQAir HealthPro hyper-HEPA+ floor model three-stage air filters — of the type found in hospitals, surgery rooms, and clean rooms — located in every classroom and main processing areas. These units remove Coronavirus from the air and other ultra-fine particles smaller than a virus. They also remove smoke particles and harmful fumes and gasses.

We also have IQAirVisual air quality monitors located in every classroom and reception area. They tell us by remote before school and throughout the day how well we are continuing to succeed in cleaning the air of large, medium, small, and fine particles, droplets, and aerosol mist that can also carry Coronavirus. 

We continuously monitor outside air by means of comprehensive data sets that include: the USA Environmental Protection Agency’s system of wide-area and local air quality monitors; the PurpleAir network of monitors; the IQAir network of monitors; three key websites for wildfire smoke, wind direction, and air quality forecasting; and, and other sites for weather elements forecasts. 

Since the Coronavirus also transfers significantly by air and having high-quality air moving rapidly and exchanging often are critical to mitigating the transfer and absorption of the virus, we work closely with our host buildings to adjust the HVAC systems as necessary to provide the best possible air at all times. They have highly rated MERV-13 and MERV-14 air filters.

For safety and to mitigate transmission of the Coronavirus, the children in every classroom meet each day and work all day long with the same continuous group members and the same primary teachers. They also eat, sleep, and play outside as an in-tact group separated from other children’s groups and staff.

Staff wear masks, reduce interactions outside of classrooms, maintain safe distancing, and participate in the thorough cleaning every day before, during, and after the children are present. They are also briefed extensively on virus related best health practices and trained in all of the key activities related to prevention and mitigation.

We share with parents and family members information about children’s activities during the day by means of online photos, videos, and Daily Stories in line with organic Weekly Plans and interests emerging from individual children and their learning groups.

Parents, family members, building management, and government agencies can reach us 24/7 to get or give essential information, including alerts, processing medical concerns, and clarifying regular curriculum, policies, and business issues.

We provide regular and frequent information about how the new health and safety processes are working as part of our Daily Stories and Weekly Plans for each classroom. The posts are on our private, secure website Connections where every enrolled family has access to information from all of the classrooms in our two, soon to be three, centers. The posts are interactive and the information, including photos of daily activities, is downloadable. Parents, immediate family members, and extended family members from around the world connect daily for the latest news and classroom activities.
