Each year, the IB continues to grow — more schools, more countries, and more students sitting exams. When the IB releases its annual statistics, one number often surprises students: just how many people are taking the Diploma Programme worldwide.
At first glance, this can feel intimidating. Bigger cohorts can mean more competition, more comparison, and more pressure. But the reality is more nuanced.
This article explains how many students took the IB in 2025, why those numbers keep rising, and what cohort size actually means for individual students.

How Many Students Took the IB in 2025?
In the May 2025 session, over 200,000 students worldwide participated in IB assessments across the Diploma Programme and related pathways.
This marks another year of steady growth and confirms the IB’s position as one of the largest international secondary qualifications in the world.
The IB now operates across:
- Thousands of schools
- Over 150 countries
- Diverse educational systems and languages
This scale is important — but not in the way many students think.
Why the Number of IB Students Keeps Increasing
IB participation has grown consistently for several reasons.
First, universities continue to recognise and value the IB Diploma for its academic rigour and breadth.
Second, more schools are adopting the IB to offer internationally recognised pathways.
Third, families increasingly see the IB as preparation not just for exams, but for independent thinking, time management, and academic writing.
