Preschool through Grade 12

Volunteer and Give


We inherited ISB from past generations of parents; now it is our turn to make a difference.

Philanthropy at ISB means volunteering time, talent, experience and contributing to the ISB Fund for Excellence.

We encourage parents to get involved as volunteers at events, as chaperons, in the Parent-Teacher Organization (PTO), at school activities and as room parents. Some parents serve on the school’s governing board as Trustees, some in committees, some as representatives on the PTO leadership team.

Whether you can spare two hours or 20, your support is valuable and needed at ISB.

Parent-Teacher Organization (PTO)

The PTO brings the ISB community together, representing our community both within and beyond the school by:

  • Sharing Ideas: The PTO wants to hear from you, welcomes any suggestions and ideas that will make the organization more effective.
  • Volunteering: Your involvement in the PTO’s numerous events and activities is an opportunity to make a difference. View PTO volunteering opportunities.
  • Fundraising: The PTO hosts fundraising events, such as the bread sale, holiday baskets and others, to benefit enrichment programs for the community, including special guest speakers and workshops.
  • Ready to get involved? Email us for more details.

    ISB Fund for Excellence

    As a private independent school that does not receive any direct funding from the U.S. or French governments, ISB depends on and graciously encourages your participation in our annual fund, the ISB Fund for Excellence.

    This is our fundraising priority. We solicit every member of the ISB community to donate to the Fund annually, and we gratefully accept gifts of all sizes. We designate funds to our areas of greatest need, usually within the same year (unless otherwise specified).

    The 2016-2017 campaign supports four major areas:

  • The Cambridge campus expansion
  • Curriculum enhancements
  • Development of our athletics offerings
  • Maintenance of our historical building

  • Donors are also welcome to restrict their gifts to six categories:

  • Academic programs
  • Facilities improvements
  • Faculty professional development
  • Financial aid
  • Performing and visual arts
  • Technological upgrades

    ISB Benefit Gala

    ISB’s Benefit Gala is the school’s largest fundraiser. More than an elegant evening to celebrate the ISB community, it is an evening of generosity for the future of our institution.

    Since 2008, the Gala has contributed immensely to the annual fundraising campaign, raising funds for financial aid, the new playground, media center, new classroom technologies, innovative programs such as virtual school, and more.

    The Gala takes place each spring. ISB’s community supports and participates through volunteer time; donations of goods and services; cash contributions; and auction, raffle and ticket purchases.

    We welcome everyone to get involved and to attend. Contact us to learn more about volunteer opportunities.
