CDS Campus Reopening: Context and Updates

COVID-19 Vaccination

We encourage all eligible staff, volunteers, and students/family members to be vaccinated for COVID-19. Resources to get vaccinated are available through the city, as described here.

Face Coverings and Other Essential Protective Gear

Updated September 1, 2021

How CDPH’s face covering requirements will be satisfied and enforced:‰ 

  • Face masks are required while indoors, regardless of vaccination status, except while eating, drinking, or (for students) napping.
  • Though not required in the SFDPH guidelines, CDS will continue to require all individuals on campus to wear masks outside, except while eating or drinking.
  • Persons exempted from wearing a face covering due to a medical condition must wear a nonrestrictive alternative, such as a face shield with a drape on the bottom edge, as long as their condition permits it. 
  • In limited situations where a face covering cannot be used for pedagogical or developmental reasons, (e.g., communicating or assisting young children or those with special needs) a face shield with a drape (per CDPH guidelines) can be used instead of a face covering while in the classroom as long as the wearer maintains physical distance from others. Staff must return to wearing a face covering outside of the classroom. 
  • CDS will keep a supply of face masks for people who forget to bring their own.
CDS Travel Policy

Last updated September 21, 2021

Vaccinated individuals (no quarantine required)

  • International travel: No quarantine, but the U.S. requires a negative test within 3 days of flight to re-enter the country. You must then test again 3-5 days after returning and share those test results with

Unvaccinated individuals (all travel - domestic or international)

  • Get tested 1-3 days before the trip (For international travel to re-enter the U.S., this will be checked).
  • Quarantine for at least 7 days upon arrival. 
    • Option 1: Get tested 3-5 days after arrival and share results to end quarantine on day 7. 
    • Option 2: No test, 10 day quarantine.
  • Please share your travel plans and test results with (and be sure to inform your teaching team of the absence!).
  • Note: This does NOT apply to situations in which you are not exposed to others outside your household. For example, if your family were to drive to a destination and limit contact with others outside the household for the duration of the trip, this would NOT require quarantine.
What to Do If Your Student Has COVID-19 Symptoms

Last updated September 21, 2021

All persons entering the building or campus must screen themselves for symptoms and exposure to COVID-19, including staff, students, parents/caregivers, contractors, visitors, and government officials. Emergency personnel responding to a 9-1-1 call are exempted. 

  • At drop off, families must report if any of the following is true (note: symptoms explained by another, documented condition do not require preventative action):
    • Fever (100.4°F/38°C or higher) 
    • Sore throat 
    • Cough (for children with chronic cough from allergies or asthma, a change in their cough from baseline) 
    • Difficulty breathing (for children with asthma, a change from their baseline breathing) 
    • Nasal congestion or runny nose
    • Diarrhea, nausea, or vomiting 
    • Loss of taste or smell that started in the last 10 days. Children may say that food “tastes bad” or “tastes funny.” 
    • New onset of severe headache
    • Fatigue
    • Muscle aches or body aches
    • Exposure to a positive COVID-19 case
  • Children with symptoms of COVID-19 or a fever will be sent home and required to seek a PCR based COVID-19 test. 
  • If your child tests negative for the virus (no virus found), they may only return to school after symptoms have resolved and they are fever-free for 24 hours without use of fever suppressing medication. 
  • Children who pass screening will wash their hands with soap and water or clean their hands with hand sanitizer before they enter the building or program.
  • Adults with symptoms or exposure to COVID-19 will not be allowed on campus. We will keep students who are waiting to be picked up in a designated isolation room. 
  • If a student is sick and unable to attend school, parents will be asked to fill out this form. Please then email your student's TEACHER as well as
What to Do When Someone Is Exposed to COVID-19 or Has Confirmed COVID-19

Updated September 15, 2021

Returning to school after COVID-19 exposure:

  • People who are fully vaccinated for COVID-19 or have had COVID-19 do not have to quarantine after close contact as long as they do not have symptoms. A close contact is someone who was within 6 feet of an infected person for a total of 15 minutes or more over 24 hours (for example, three individual 5-minute periods over the course of a day) while the infected person was contagious. 
  • Unvaccinated children and youth only need to quarantine for outdoor exposures at schools if close contacts happened:
    • During high-contact sports or dance
    • Student and infected person were unmasked and stationary
  • Per CDPH guidance, there is a modified quarantine for unvaccinated TK-12 students who have close contact at school. They can continue to attend school if: 
    • Both the student and the infected person wore face masks consistently and correctly;  
    • The student continues to appropriately mask, as required;  
    • The student gets tested for COVID-19 twice a week during the Quarantine period; and 
    • The student does not develop any COVID-19 symptoms that are new or unexplained by another condition. 
    • Students must not participate in extracurricular activities such as sports until their quarantine period ends.
    • This exception does not apply to adult-to-adult transmission in the classroom.
  • Note that "modified quarantine" only applies to classroom settings for students in grades TK and up. It would not apply to students in preschool, Aftercare, music lessons, or any other kind of youth program. Students who are exposed to a positive case in these settings will have to quarantine and can return after the following:
    • 7 days after last close contact, as long as a PCR test is taken on day 5 and returns negative results to
    • 10 days after last close contact with no test (as long as no symptoms have developed)
      • If symptoms develop and student tests negative, quarantine will be 14 days after last close contact with the positive case.
  • Please report student absences to and copy your classroom teachers, and fill out the student absence form here.

Returning to school after COVID-19 positive test/diagnosis:

  • Students who have tested positive for COVID-19 or been diagnosed with COVID-19 must isolate at home for at least 10 days. They can return to campus after 10 days if their symptoms have been resolved for 24 hours.
  • Please report student absences to and copy your classroom teachers, and fill out the student absence form here.
Ventilation and Use of Outdoor Space

Increasing indoor air circulation lowers the risk of infection by “diluting” any infectious respiratory droplets with outdoor air. Being outside is even lower risk. 

Outdoor spaces

  • Classrooms/groups will do as many activities outside as possible, especially snacks/meals and exercise.  

Indoor spaces 

  • Maintaining good ventilation indoors is key to mitigating the spread of COVID-19.
  • During wildfires or other times when air quality is poor, CDS will prioritize maintaining healthy air quality indoors. We may remain open even if we need to close windows - we will use our HVAC system and portable air cleaners (HEPA filters).

General ventilation recommendations:  

  • Indoor spaces will open windows to increase natural ventilation with outdoor air when health and safety allow. When possible, leave room doors slightly open to promote flow of outdoor air through the indoor space. 
  • Do not prop or wedge open fire doors. Continue to follow fire and building safety requirements. 
  • For buildings with HVAC system (601 building): 
    • We will open outdoor air dampers and close recirculation dampers (“economizers”). This will maximize the amount of outdoor air that the HVAC system takes in and minimize the amount of indoor air that is recirculated. 
    • If you can use higher-efficiency air filters without reducing airflow or damaging your HVAC system, use air filters rated MERV13 or better. 
    • Disable “demand-control ventilation controls” so fans keep running even when a room doesn’t need to be heated or cooled. 
    • If your HVAC system has a timer, set it to run at least 1-2 hours before the building opens until 2-3 hours after everyone has left the building, including custodial staff.

Our Approach

The rationale for our opening plan is to focus on three key priorities: the physical and emotional Health and Safety of all members of our community, Academic Continuity, and preservation of the Value of a CDS education. We are prioritizing the health and safety of students, faculty, and families as well as the developmental needs of our students.

Healthy Hygiene Practices

The availability of handwashing stations and hand sanitizer, and how their use will be promoted and incorporated into routines: 

  • Staff and faculty will teach and reinforce hygiene practices:
    • Avoiding contact with one's eyes, nose, and mouth, and covering coughs and sneezes among students and staff. 
    • Promote hand washing throughout the day, especially before and after eating, after using the toilet, and after handling garbage, or removing gloves. 
  • Every classroom/instructional space and common area (staff work rooms, eating areas) will have hand and surface sanitizer. 
Physical Distancing

There will be limited, strategic use of physical distancing for higher-risk activities, such as:

  • During dance, exercise or singing. 
  • When unvaccinated children are not wearing masks, such as during meals.
Cleaning and Disinfection

How shared surfaces will be regularly cleaned and disinfected and how use of shared items will be minimized:

  • CDS will clean all surfaces/areas once per day.
  • The CDPH recommends additional disinfection only after a confirmed COVID-19 case: 
    • If a facility has had a sick person with COVID-19 within the last 24 hours, clean AND disinfect the spaces occupied by that person during that time
  • All classrooms have been issued bottles of hand sanitizer, bottles of disinfectant, disinfectant wipes, and rolls of paper towels to inhibit the spread of germs.
Opportunities to Address Equity

CDS has supported equity in a number of different ways throughout the pandemic, including the following: 

  1. Financial support for any families experiencing hardship is provided through a process facilitated by the head of school and director of finance. Families requesting redistribution of payments, forgiveness of some payments and additional sliding scale support was provided as well as support for individual basic needs (food, rent, short-term childcare support). All support was provided based upon documented financial needs.
  2. Students were all provided devices (Macbooks or iPads) with necessary applications. Some families were provided hot spots if they did not have adequate internet access and in some cases funding was provided to increase internet access and bandwidth. 
  3. CDS prioritized the support of families with caregivers in essential roles or roles that required in-person work and families who participate in our sliding scale tuition program. These families were given priority access to child care once we were allowed to offer it and to summer camps. The same prioritization is used for after school care. 
  4. In addition to supporting our internal community, CDS is mindful of the disparities in the city and has provided programming and content to our partner the Boys and Girls Club of San Francisco as well as local public school teachers in our community.
Specific Situations

Carpools and shared rides

  • Staff and families should try to carpool with the same stable group of people.  
  • Open windows and turn the fan on high, set to outdoor air.  
  • Treat the vehicle as an indoor space: everyone in the vehicle should wear a face mask.

Meals and Snacks

  • Students will eat outdoors when space and weather allow. 
  • Space students out when eating. If students are not spaced apart, assign seating during meals to keep track of close contacts during unmasked periods.  
  • Meals do not need to be individually plated or bagged.  
  • Consider starting lunch with silent eating time, followed by conversation time, to discourage talking while face coverings are off. 

Other Situations

  • Anyone providing special services to a student would be allowed to visit campus following our normal visitor protocol, regardless of vaccination status.
  • Festivals, performances and other events that involve families; tours; and open houses are allowed if all participants are fully vaccinated. If indoors, all participants must wear face coverings. CDS will keep a log of all persons who attend. 
  • Field trips are allowed.
  • Sports, dance, exercise, singing, and chanting are allowed. Wind instruments are allowed ONLY outdoors. These activities continue to be higher-risk for COVID-19 because people breathe more air and breathe more forcefully when doing these activities. Masks must be worn indoors for all activities.
Communication Plans

All general COVID-19 related CDS information will be posted on our website. Please visit this page for the most up-to-date information about general COVID-19 practices and precautions.

As needed, CDS will communicate with CDS staff and families about cases and exposures in our community in accordance with all FERPA, HIPAA, and Cal OSHA regulations. Specific guidelines are listed below.

Staff Notification of a Potential COVID-19 Exposure within One Business Day: Cal/OSHA 3205(c)(3)(B)(3) states that “the employer shall. . . when there has been a COVID-19 case at the place of employment. . . give notice of the potential COVID-19 exposure, within one business day, to. . . all employees who may have had COVID-19 exposure and their authorized representatives [and] independent contractors, and other employers present at the workplace during the high-risk exposure period [emphasis added].”

  • Recommended Action:
    • If a notification time period of one business day or less is not already specified in your existing safety protocols, we recommend that institutions insert a time period of “one business day” in their notification plans and take steps to implement accordingly.

Notification to Cal/OSHA for COVID-19-Related Serious Illnesses or Death: OSHA 3205(c)(9)(B) states that “the employer shall report immediately to the Division [Cal/OSHA] any COVID-19-related serious illnesses or death, as defined under section 330(h), of an employee occurring in a place of employment or in connection with any employment.”

  • Recommended Action:
    • If notifying OSHA is not already documented in your existing safety protocols, we recommend inserting the following language and taking steps to implement accordingly:
      • It is our policy to:
        • Report information about COVID-19 cases at our workplace to the local health department whenever required by law, and provide any related information requested by the local health department.
        • Report immediately to Cal/OSHA any COVID-19-related serious illnesses or death, as defined under CCR Title 8 section 330(h), of an employee occurring in our place of employment or in connection with any employment.
