A special meeting of the School Committee on Tuesday has only one agenda item: ratifying a contract for Victoria Greer to become superintendent of Cambridge Public Schools effective Jan. 1.

The town of Sharon is expected to reach a $750,000 settlement Wednesday with Cambridge’s acting superintendent of schools, Victoria Greer, over a racial discrimination complaint filed with the state.

Nearly one-quarter of the city’s high schoolers walked out of classes Tuesday to bring attention to the impact of sexual assault and harassment on students, despite a similar walkout being held more than five years earlier leading to an “action plan” that got enthusiastic support in 2017.

The city’s latest teen health survey has some data that rattled participants at a Tuesday meeting, including a “historic” level of mental health struggle among kids, several dozens of whom had thoughts of suicide over the past months.

To some administrators’ dismay, election commissioners called schools some of the most stable places to hold balloting in the city’s 34 precincts – and other officials looked for ways to ensure the relationship continues.

All age-eligible students in Cambridge Public Schools must be vaccinated against Covid-19 or lose out on extracurricular activities starting Nov. 29, the School Committee decided in accepting a recommendation by interim superintendent Victoria Greer.

The first day of Cambridge Public Schools found interim superintendent Victoria Greer greeting students and staff at the Haggerty School and taking questions about how the district welcomes back students after 18 months of coronavirus.

Public school students will be back in classes by Monday, making district staff vaccinations a hot topic – but perhaps surprisingly given the ongoing national debate, not a controversial one.

The city will undertake a $1 million study over at least the next year on how to refresh and expand its aging elementary schools, though doubt was cast Monday that the improvements will be on as grand a scale as what’s been seen on recent campus projects.

Lines in the sand are being drawn in the district’s decision to suspend two teachers without pay for a day for declining to participate in administering the MCAS tests to students. A letter supporting the two educators signed by 189 educators was delivered to superintendent Kenneth Salim’s office.
