CHS Mask Mandate

Today, because Cohasset High School (CHS) and Cohasset Middle School (CMS) exceeded the 80% vaccination threshold (fully vaccinated staff and students in both schools combined), the Department of Elementary and Secondary Education (DESE) granted approval for CHS and CMS (no other schools in the district) to lift the mask mandate requirement for fully vaccinated individuals (individuals who have two doses of the Pfizer or Moderna or the single dose of the Johnson & Johnson’s Jannsen). At the November 17 Cohasset School Committee Meeting the Cohasset School Committee voted that masks will not be required for fully vaccinated individuals at CHS once students and staff in the combined CHS and CMS building reach the 80% vaccination threshold, we receive DESE approval, and we are operationally prepared to make this adjustment. It was also decided by vote that vaccinated individuals at CMS will remain masked until January 1, 2022. As a result of these school committee votes and DESE approval, the following changes will take place for Cohasset Middle School and Cohasset High School:


  • Beginning on Monday, December 6, 2021, the masking requirement will be lifted for fully vaccinated individuals at CHS only. Unvaccinated individuals are required to continue to wear masks in accordance with DESE guidelines.
  • All Cohasset Middle School staff and students will continue to wear masks until January 1, 2022. As of this time, after January 1, masking will not be required for fully vaccinated individuals at CMS.

 Masks will continue to be worn by all individuals at both CHS and CMS in the following locations:

  • On the bus (wearing a mask on the bus is a federal mandate)
  • In our nurses’ offices (at both CHS and CMS)
  • In our shared learning commons
  • Masking rules for athletics will follow MIAA guidelines

 Masking will be required for all visitors to Cohasset Public Schools until further notice. This requirement includes all families who are attending sporting, theater, and musical events.

 It should be noted that, regardless of vaccination status, individuals at Cohasset High School (beginning on December 6) and Cohasset Middle School (after January 1) may certainly choose to continue to wear a mask while in school. Any choice to wear a mask should not be viewed as an indication of one’s vaccination status. As a reminder, if your child’s vaccination status changes from unvaccinated to vaccinated, please contact your child’s school nurse. DESE reserves the right, following consultation with medical experts and state health officials, to re-institute the Department’s mask mandate at the shared building housing Cohasset Middle School and Cohasset High School, if it becomes appropriate based on state and local public health data. Thank you for your collaboration and vigilance regarding the above rules.
