All Wednesdays during the school year are early release days to provide educators with dedicated Common Planning Time (CPT). This structured collaboration time allows educators across schools, grade levels, and departments to plan instruction, analyze student data, strengthen curriculum implementation, and develop strategies to better support all learners.

Wednesday dismissal times are:

  • Prekindergarten: 12:00 pm
  • Grades K–8 (except Next Wave/Full Circle): 1:00 pm
  • Next Wave/Full Circle: 12:10 pm (students may stay to eat school lunch)
  • Somerville High School: 1:33 pm

To preserve instructional time, the daily classroom start time will move from 8:25 a.m. to 8:20 a.m. The district anticipates that CPT will strengthen teaching practices, increase collaboration, and support improved student outcomes over time.

Somerville is a vibrant, multicultural community enriched by the many cultures, traditions, and beliefs represented among our students, families, and staff. Recognizing and honoring important religious and cultural observances throughout the year helps foster belonging, respect, and understanding across our schools. The following list highlights some of the significant observances celebrated by members of our diverse community. While it is not an exhaustive list, it reflects our ongoing commitment to acknowledging and celebrating the experiences and traditions that make Somerville Public Schools a welcoming community for all.
