International Baccalaureate (IB) Performance Highlights
The British International School of Houston's Class of 2025 results showcase a number of impressive statistics for this cohort, both individually and collectively:
This year’s results include several other standout achievements:
Students achieved a 100% pass rate in the IB Career-related Programme (CP) and a 92% pass rate in the IB Diploma Programme (DP), well above the global average of 81.26%.
71% of students achieved scores at or above the world average.
24% of students scored above 40 points – a level attained by only 4% of IBDP candidates worldwide this year.
The average for all grades was 5.2, significantly above the world average of 4.89.
49% of all grades were 6 or 7 (equivalent to A* – A at A Level).
Five students earned a bilingual diploma, which requires literature qualifications in two languages – giving them a significant advantage when applying to universities and entering the global workforce.
In addition, the Class of 2025 received an impressive $6.3 million USD in total scholarship offers. At BIS Houston, we don’t just prepare students for college – we empower them to access the world’s most competitive academic institutions.

IGCSE Results
The GCSE and IGCSE are internationally respected qualifications studied by students between 14 and 16 years old. Respected by employers and universities, they cover a broad range of core subjects including maths, English, and science, as well as world languages, humanities, social sciences, art, drama, and music. They are the most academically challenging qualifications currently on offer for 14- to 16-year-old students worldwide, and many candidates go on to study the International Baccalaureate (IB).
We are proud to celebrate the academic results achieved by our students. These outcomes reflect their hard work and determination, supported by our dedicated expert teaching team.
