Upper School students are immersed in a broad and demanding program that comprises a choice of rigorous curricula. For students whose mother tongue is not English, the School offers language support through an extensive English-as-an-Additional Language program. Those following the American curriculum through to the High School Diploma can find additional challenge by taking one or more of the over 20 Advanced Placement courses on offer. Another option during the final two years of Upper School is the opportunity to earn an International Baccalaureate Diploma.

Both qualifications are recognized by universities in over 70 countries around the world. In preparation for college or university, Upper School students benefit from a four-year College Counseling curriculum that is unique to most international schools and, in the final two years, they receive one-to-one academic advice from experienced counselors. TASIS England supports students and their families as they identify the educational pathway that is right for them.
