What Is IB DP? The Official 2025–2027 Explanation
What is IB DP? The International Baccalaureate® Diploma Programme (IB DP) is a two-year, academically challenging and balanced programme for students aged 16–19 that prepares them for success at university and life beyond. Offered in over 5,800 IB World Schools across more than 160 countries, the IB DP program develops inquiring, knowledgeable, and caring young people who help create a better and more peaceful world through intercultural understanding and respect.
As stated on the official IBO website:
“A future-ready programme that builds students’ inquiring mindset, fosters their desire to learn, and prepares them to excel at their careers and lead meaningful lives.”
Unlike national curricula, the IB DP course requires students to study six subjects across disciplines plus the unique DP Core (Theory of Knowledge, Extended Essay, Creativity, Activity, Service), ensuring breadth and depth while developing research, critical thinking, and global-mindedness.
