All Marin public school campuses will suspend in-person classroom instruction to students for at least two weeks beginning Monday because of coronavirus concerns, officials announced Friday.

The decision, which still leaves the campuses open for specific community resources — such as subsidized school lunches — and adult staff, is based on the recommendation of the Marin County public health department and is fully supported by the Marin County Superintendent of Schools, officials said.

The decision affects about 34,000 students in 90 schools. No student in Marin public schools has so far tested positive for the coronavirus, officials said.

“The landscape related to the COVID-19 virus is rapidly changing, especially in the Bay Area,” said Dr. Matt Willis, Marin County public health officer. “This is one part of a series of steps we’re taking to support social distancing, to better protect the community at large.”

The suspension of classes is following a series of policies for “social distancing” in response to the virus, including limiting large gatherings and tightening visitation protocols at nursing homes.

“Marin has a large population of seniors — this is one important reason we need to be proactive,” Willis added. “These are key steps we can take to weather this together.”

According to Friday’s statement, the Marin County Office of Education is working with local districts, schools and community organizations to meet the needs of students who rely on schools for subsidized meals, special care and other resources. Families will receive information from respective schools related to these needs and opportunities for students to continue learning from home, Mary Jane Burke, Marin County Superintendent of Schools, said.

“Recognizing the challenges that a school closure poses for many families in our community, we are making this decision with a heavy heart but for

the greater good,” Burke said in the statement. “Our priority is always the safety and well-being of our students.

“For the past month, our schools have received constant guidance from public health officials and remained aligned with their professional opinions. Given this unprecedented situation around the globe, we are acting in step with Marin Public Health and out of concern for all members of our community.”

At least some schools in Marin’s largest school district, Novato Unified School District, have already trained their students to take classes through distance learning on home computers, according to Kate Osborn, a coordinator at Marin County Office of Education who has a fourth-grader at a Novato elementary school.

Osborn said her daughter was able to pick up Google Classroom, which will be used for instruction and to communicate with teachers and classmates, readily.

“It’s super easy,” she said. “My daughter’s teacher walked them through through all the steps and she has it down. She didn’t seem at all confused. I think they’re very well-prepared.”

Mill Valley School District were among the districts that had already set up remote learning schedule protocols to give instruction via home computers and iPads.

“The resources and lessons prepared by teachers, and provided to students each day will be focused on reviewing previous curriculum and deepening core knowledge and skills,” said Amanda Finlaw, communications specialist, in a bulletin to parents. “We suggest that you set up a consistent ‘classroom space’ in your home for students to engage in their work if they are at home all day.”

Mill Valley officials planned to communicate with families and relay daily school assignments via Parent Square, a website application, Finlaw said.

Miller Creek School District also sent out a temporary closure notice Friday to school families.

“We would like to emphasize that there are no known cases of COVID-19 among Miller Creek School District staff or students at this time,” said the notice, signed by interim superintendent Becky Rosales and assistant superintendent Kristy Treewater.

“However, as the coronavirus (COVID-19) situation has unfolded, it has become clear that the most responsible action, at this moment, is for us to take a proactive versus reactive approach to social distancing and other containment measures,” the statement said.

Marin’s private schools are also closing on an individual basis. Marin Country Day School in Corte Madera closed its doors through March 20. Branson School in Ross announced a two-week closure beginning Friday, with remote instruction starting Wednesday. San Domenico School in San Anselmo said it would close and use remote instruction as of Friday until spring break.

Marin’s colleges and universities are following with similar measures.

On Friday, Mary B. Marcy, president of Dominican University of California in San Rafael, told students and staff that Dominican will suspend regular classes the week of March 16-20. The university will begin online course delivery on March 23, to be continued as long as necessary through the spring semester, Marcy said.

At College of Marin, president David Wain Coon said Friday that in-person classes at the college’s campuses in Kentfield and Novato would be suspended effective March 23, but remote learning will be offered during that time. Remote classes will also be delivered to students during spring break, March 16-22, he said.

“College officials will continue to work closely with Marin Health and Human Services to decide when in-person instruction will resume,” Wain Coon said. “We will update faculty, staff and students regularly, as new information becomes available.”

Wain Coon added that the “College of Marin campuses are not closing. Campus buildings will remain open, and we anticipate that most non-instructional operations will proceed normally.”

“Offices and classrooms will be available to instructors so they may prepare materials and teach from their offices or classrooms,” he added “Instructors should work with their dean if they have questions about access.”

All Catholic schools in the Archdiocese of San Francisco — including seven schools in Marin — already had announced closures to start as of Thursday after a student in one of their schools outside of Marin tested positive for the coronavirus. The Catholic schools were set to resume classes as of March 25, officials said.
