How is our High School Different?

Traditionally, American high school students select a wide-range of subjects, which they study for varying amounts of time. Through the IGCSE, we offer a more carefully constructed approach to ensure that your child is the strongest possible candidate for college acceptance. The IGCSE also uses an internationally-benchmarked assessment system valued by universities worldwide.

Understanding the IGCSE

Internationally-respected, the IGCSE curriculum is a two-year cycle during which your child will study ten subjects in great depth. This approach provides the time to establish a solid foundation upon which the rest of their high school progress will depend.

Subjects Studied

During Grades 9 and 10, our students study eight compulsory courses:

  • English Language 
  • English Literature
  • Mathematics
  • Biology
  • Chemistry
  • Physics
  • History
  • Foreign Language (either French or Spanish)
  • Physical Education

Each student also chooses two options to round out their schedule. Options may include:

  • Art
  • Drama
  • Music
  • Business Studies
  • Geography
  • Computer Science
  • Digital Applications
  • French (as a second foreign language)
  • Spanish (as a second foreign language)
  • Advanced Physical Education.

Preparation for the IB diploma

We are the only private school in Boston to offer the IGCSE. We choose it because we feel it is the very best preparation for the International Baccalaureate (IB) Diploma Programme, studied in the final two years of our High School.
