An Introduction to the IB Diploma Programme 

At British International School of Boston, we know that no program will prepare your child for the future like the International Baccalaureate Diploma Programme (IBDP) — widely regarded as one of the best pre-university curricula worldwide. The IBDP is a comprehensive two-year program at the end of High School that focuses on intensive academic study and personal growth.

Students who have progressed through our school have a strong understanding of their own learning style and are well-prepared to take on the broad and challenging scope of the IB diploma. Other students choose to join the British International School of Boston at the start of the IBDP, giving them an impressive capstone on their High School years and making them more attractive to competitive universities.


IB Diploma Subjects

All IB Diploma candidates follow six subjects, one from each of the six subject groups. (Another subject from Groups 2–4 may be taken in place of an Arts subject in Group 6).

They must take at least three subjects at Higher Level (HL) and three subjects at Standard Level (SL).

Students also study a “Core” that’s divided into the following three areas:
