International Baccalaureate: a calm, honest guide for families
The world's most portable curriculum, designed for globally mobile families.
Quick Summary
- ·The IB is a four-programme continuum (PYP, MYP, DP, CP) designed for globally mobile, university-bound students.
- ·The Diploma Programme (ages 16–19) is the most recognised, six subjects, an Extended Essay, Theory of Knowledge, and CAS.
- ·IB schools tend to cluster in major expat cities and are the most portable option if you expect to relocate again.
- ·Genuine IB delivery is expensive and teacher-intensive, the difference between a great IB school and a mediocre one is enormous.
- ·Universities in the UK, US, Europe, Singapore and Hong Kong all give IB strong consideration, often with explicit conversion tables.
What the IB curriculum actually is
The International Baccalaureate Organization (IBO), founded in Geneva in 1968, runs four programmes intended to be taken end-to-end or selectively.
The IB is built around a single educational philosophy rather than a national curriculum. Schools licensed by the IBO commit to delivering programmes that emphasise inquiry, breadth across subject groups, and structured reflection. The IB writes the framework and assessment standards; schools deliver the day-to-day teaching with significant local flexibility.
There are four IB programmes: the Primary Years Programme (PYP, ages 3–12), the Middle Years Programme (MYP, ages 11–16), the Diploma Programme (DP, ages 16–19), and the Career-related Programme (CP, ages 16–19). The DP is by far the most globally recognised, many families pick a school for the DP and accept whatever the school does at younger ages.
Importantly, IB ≠ international school. Many bilingual and national schools also offer the DP as a sixth-form option, and many international schools that brand themselves 'IB' actually only offer the DP at the top, with British or American programmes lower down. Always confirm which programmes are authorised at which year groups.
How the programme is structured
Inquiry-led, transdisciplinary primary curriculum. No external exams; assessment is teacher-led and portfolio-based.
Eight subject groups with concept-based learning, a Personal Project in the final year, and optional MYP eAssessment.
Six subjects (three Higher Level, three Standard Level), Extended Essay, Theory of Knowledge, and CAS. External exams scored out of 45.
DP courses combined with a career-related qualification, a vocational alternative to the full Diploma.
Who IB suits, and who it doesn't
- · Families likely to relocate again, the DP is the most universally recognised school-leaving qualification in the world.
- · Strong all-rounders who genuinely enjoy breadth (a language, a science, a humanity, maths and an art).
- · Students considering universities in multiple countries simultaneously.
- · Children who thrive on writing, project work and reflection rather than pure exam practice.
- · Specialists who already know they want to study one narrow subject (UK A-Levels often suit better).
- · Students who struggle with sustained writing under time pressure, the EE and TOK essay are not negotiable.
- · Families on a tight budget, full IB delivery is consistently among the most expensive school models.
- · Late teens with significant gaps in a second language, DP language requirements can be unforgiving.
What it actually costs
IB fees are a function of the city, not really the curriculum. The IB itself adds cost through teacher training, exam fees and authorisation requirements.
In Asia and the Middle East, full-IB schools typically sit at the top of the local fee market, USD 25,000–50,000+ per year is common. In Europe, IB schools often command a premium over national systems but are below British or American boarding equivalents.
Expect IB-specific costs on top of tuition: DP exam fees (paid per subject), Extended Essay supervision, occasional CAS trip costs, and sometimes 'programme fees' that fund teacher training. Ask schools for an all-in number for Year 12 and Year 13.
Scholarships exist but are scarcer than at British or American schools. A handful of UWC schools offer needs-based scholarships for the DP, worth investigating if your child has a strong academic and service profile.
University and life outcomes
The IB Diploma is one of the most universally accepted school-leaving qualifications in the world. The trade-off is that it asks for breadth at exactly the age many students want to specialise.
UK universities use UCAS tariff conversions: typically 38–40 IB points are competitive for top universities, with 40+ required for Oxford, Cambridge, LSE and similar. US universities generally treat the DP as the strongest signal a school can send and routinely accept HL subjects for credit.
Continental European, Singaporean and Hong Kong universities often have the cleanest IB conversion frameworks, sometimes more generous than for A-Levels. This is part of why the IB tends to dominate at international schools in cities with multi-destination university aspirations.
Beyond university entry, IB graduates report higher self-rated readiness for academic writing and independent research. The trade-off is real workload, DP students consistently report 30–40 hours of study per week outside class.
Choosing a IB school well
Confirm authorised programmes
Check the IBO 'Find an IB World School' database. Schools listed for one programme but not another can't legally call themselves a full IB school.
Look at the average DP score
World average is 30–32. Strong schools sit at 35+; elite schools at 38+. Ask for the school's three-year trend, not just the latest year.
Inspect HL subject availability
The number of HL combinations a school can actually deliver matters more than the marketing. Smaller schools often can't run niche HLs.
Talk to current DP families
Workload, pastoral support, EE supervision and university counselling vary hugely, far more than promotional materials suggest.
Check teacher continuity
DP delivery quality depends on experienced IB teachers. Schools with high turnover struggle to maintain results.
Don't ignore the lower years
If your child is 7, 'great DP results' won't help you. PYP delivery is highly variable; visit and ask to see actual transdisciplinary unit plans.

Common mistakes families make with IB
- Picking a school for its IB brand without checking which programmes are actually authorised at your child's year group.
- Assuming the DP is always 'better' than A-Levels, for a focused student aiming at a specific UK course, A-Levels can be the smarter route.
- Underestimating workload. Students who thrive in IGCSEs sometimes burn out under the DP's constant coursework deadlines.
- Confusing 'IB-inspired' or 'IB-style' with actual IB authorisation. Only IBO-authorised schools can issue the Diploma.
- Locking in the DP without genuinely considering Higher Level subject availability, niche HLs are not always offered.

- It's harder in breadth, six subjects plus the core (EE, TOK, CAS). A-Levels are usually three or four subjects studied more deeply. Strong students do well in either, but the IB workload is consistently rated higher week-to-week.
- They don't 'prefer' it but they understand it well, and HL subjects often translate into university credit. For US-bound families, the DP is a very competitive signal, particularly with strong HL grades and a thoughtful Extended Essay.
- Yes, but it's harder than the reverse. The MYP doesn't follow the IGCSE syllabi exactly, so a switch in Year 10 or 11 typically means filling subject gaps. Plan early or pick a school that lets you take IGCSEs alongside MYP.
- The DP is recognised by virtually every university worldwide, but conversion tables vary. UK universities use UCAS tariff; US universities give credit for HL; European universities often have explicit DP entry routes.
- World average is around 30 points. 35+ is competitive at most universities. 40+ is required for Oxbridge, top-tier US, LSE, Imperial, NUS, HKU and similar. The maximum score is 45.
- Continuity is genuinely valuable, children who do PYP and MYP arrive at the DP fluent in inquiry and reflection. But continuum delivery is expensive and a great DP-only school can outperform a mediocre full continuum school.
