COVID-19 Information

We actively monitor the latest information regarding the Coronavirus (COVID-19) and consistently follow guidelines from Marin County Public Health (MCPH) and Marin County Office of Education (MCOE).

The health and well-being of the MdTL school community is our highest priority. This page provides information and resources for MdTL families and will be updated as protocols evolve.

Our Collective Responsibility: The MdTL Commitment

As a Montessori de Terra Linda community member, I understand it is my responsibility to protect myself, my children, and also those around me, including those who may be more vulnerable, in order to reduce the spread of COVID-19 in Marin. I will do my part by acting in a responsible manner at school and away from school, understanding that taking intentional action for my family’s health and safety actually works to protect the community at large. I agree to align my actions with all guidance, policies, procedures, and orders related to COVID-19 implemented by the state, county, and the school.

MdTL's School Site Protection Plan

MdTL has a published SSPP which was initially submitted on August 20, 2020, as a required step in reopening our campus. It was updated for the 2021-22 school year and again in October of 2021 as guidance and regulations changed. MdTL's current SSPP may be referenced here

2021-2022 Protocols

  • Staff and students in all program levels consistently wear masks at school
    • 10/12/21 Update: masks are no longer required outdoors
    • 1/04/22 Update: masks required indoors and out
    • 3/14/22 Update: masks are now optional on campus. Each MdTL family may decide what is best for their child
  • All MdTL staff are vaccinated for COVID-19
  • Students and staff with new illness symptoms must stay home and follow current Marin County Public Health protocols before returning to school

  • Routine surveillance COVID testing for all students (at-home tests for Pre-Primary and Primary students, testing at school for Elementary students)
  • Frequent and consistent hand washing


All children enrolled at MdTL participated in weekly surveillance testing for COVID-19 through February of 2022, which strengthened our community’s defenses against the spread of the COVID virus, thereby keeping our children safe and our school open and fully functioning. As of March 2022, testing is only required when a child is symptomatic or has had a known exposure.

Pre-Primary and Primary

10/31/21 - MdTL has been approved to participate in the California Department of Public Health at-home COVID-19 testing program for preschool age children. MdTL Pre-Primary & Primary families  test their children at home once a week using a BinaxNow Rapid Antigen Test, provided free to each family by the California Department of Public Health. The rapid tests may also be used if a child is symptomatic. 


We launched our in-school COVID testing program for our Elementary students the first week in September 2021 in partnership with the California Department of Public Health’s Rapid Antigen Testing Program for K-12 schools. This has allowed us to facilitate biweekly surveillance testing of students at school though self-swabbing rapid tests. In the event any symptoms are present in an Elementary student, a rapid test is administered.

  • Symptomatic Testing: COVID testing for anyone who develops any symptoms that are listed as requiring confirmation of a negative COVID test to return to school.
  • Surveillance Testing: Weekly testing of asymptomatic students as a part of our overall COVID-19 mitigation strategy, in the hopes that asymptomatic cases of COVID can be detected prior to exposures within our school community.
  • BinaxNow: Brand of rapid antigen test supplied to MdTL by the California Department of Public Health.
