Preschool through Grade 12

Student Services

ISB offers comprehensive student support services to help keep our students – and their families – safe, healthy and happy.


Students may bring a box lunch to school or sign up for ISB’s Hot Lunch Program, which includes the following options:

  • Two days (Tuesday and Thursday)
  • Full week (Monday through Friday)

Our local caterer, Season to Taste Catering will deliver individually packaged lunches. They have added to their menu an International Day on Fridays to feature international cuisine from a specific country using ingredients that are responsibly sourced, seasonal, and high quality, while minimizing environmental impact. ISB lunches do not use ingredients containing tree nuts or peanuts. Pork will not be served. Please check the Portal for lunch pricing and menus.


ISB manages two dedicated bus services:

  • Route #1: Mattapan - Boston (JP/South End/Back Bay) - Charlestown - ISB
  • Route #2: Newton - Waltham - Lexington - Arlington - Belmont - ISB

The bus service fee is based on the number of children participating. Bus routes and bus sizes are re-evaluated each school year, based on need.

Students aged 4 through Grade 8, residing in the City of Cambridge, may use the Cambridge Public Schools Bus. ISB also provides discounted Charlie Cards for students age 12 and older.


We make every effort to provide a safe and healthy environment for all students.

  • A full-time nurse is on duty on the ISB campus.
