As a part of the international-themed curriculum, students are required to take four years of a foreign language: (Spanish, French, Chinese, or Japanese).

In addition to the language component, Snowden International School has the goal of having twenty five percent of each student class take part in exchange/immersion programs to foreign countries including China, Japan, Canada, England and Costa Rica.

Snowden offers students an accelerated college preparatory curriculum, the Advanced Placement program, and beginning in 2010, the International Baccalaureate Diploma Programme.

The school also has a college-like campus setting in Boston's historic Copley Square, the Princeton University Mentoring program, and formal connections to both the Freedom House, Inc. and Upward Bound at Boston University.

Students can participate in football through a cooperative program hosted by South Boston High School.
