All Cambridge Public Schools classes will stay remote until at least Jan. 11, though current guidelines would allow in-person learning to resume next week.

The School Committee will discuss or vote on three key changes to its Covid-19 response at its special meeting Tuesday: to reduce social distancing requirements; change quarantine rules; and reassess how Covid-19 metrics are used to gauge the safety of in-person learning.

Cambridge Public Schools will stay in remote learning until at least Jan. 4, superintendent Kenneth Salim said. Many parents have expressed despair, with one pediatrician worrying about a “bona fide public health crisis regarding our children’s mental health.”

The closing of Cambridge Public Schools to in-person learning that begins Thursday should be canceled through the declaration of a public health emergency, city councillor Patty Nolan told city staff at a Monday meeting.

In-person learning at public schools will resume when coronavirus thresholds dip again, but the shift to all-remote learning will continue for at least seven consecutive days through Dec. 16, superintendent Kenneth Salim said Sunday.

Contract tracing efforts show it’s highly likely two children contracted Covid-19 from adults while at in-person classes in Cambridge Public Schools, city councillors learned Monday. The district will offer testing to more students as it prepares to expand in-person classes.

New Cambridge-centric metrics of the risk of Covid-19 transmission in public schools have been approved by the School Committee, and the district has taken steps to ensure it includes perspectives from the city’s diverse population in its decision-making.

A new positive Covid-19 case at the Amigos school that moved two in-person classrooms into closure and quarantine – in addition to the three classrooms placed in quarantine in the past two weeks – has closed the school to all in-person classes until Nov. 30.

Schools will close Tuesday to in-person learning if new coronavirus metrics aren’t adopted. That will mean also resolving issues regarding inclusion in the decision process.

Former assistant superintendent for student services Victoria Greer is in the running to be Arlington’s next school superintendent. She brings strong credentials and support from a search committee, and may leave behind a clash over race in the town of Sharon.
