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.

Hot Lunch for the 2023-2024 school year will be provided through a new food services vendor, Rebecca’s Culinary Group. Rebecca’s has been in business for more than 30 years and is a trusted partner for many local K-12 independent schools, including BB&N and BC High. Introductory information, including sample menus, pricing information, and meal plan options, is available on the Parent Portal. 


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.
