Making Sense of Three Little Letters
If you’ve been hearing about the IB at school events or from other parents, you might be wondering what the Diploma actually involves. It’s a fair question, especially since the IB covers several programmes, from the early years right through to pre-university study. Families exploring IB curriculum schools tend to come across terms like the Diploma, internal assessment and the IB middle years programme, sometimes all in one conversation. This guide breaks things down simply, so you can follow along and ask useful questions when you visit schools.
Where the Diploma Sits in the IB Journey
The IB is made up of a series of programmes for different age groups. Younger children may start in the Primary Years Programme, while students aged roughly 11 to 16 can move into the IB Middle Years Programme, which runs for up to five years. The Diploma comes after that, covering the final two years of school for students aged 16 to 19.
Each stage builds on the one before, so skills practised earlier, like independent research and reflecting on their own learning, carry into the Diploma. That said, not every school offers every programme, so check which ones are available at the schools on your list.
What a Diploma Student’s Week Might Involve
The Diploma is often described as broad, but what does that look like day to day? A typical week can include a mix of the following:
- Lessons across a range of subjects, some studied in greater depth than others depending on your child’s choices.
- Coursework tasks, such as lab reports or written investigations, that count towards final grades.
- Gradual progress on a longer research paper, written on a topic your child picks.
- Activities outside the classroom, from sports and arts to community projects.
Timetables vary between IB curriculum schools, so ask how lessons and coursework deadlines are spread across each term.
Joining From a Different System
A common question is whether students need to complete the IB middle years programme before starting the Diploma. They don’t. Students can join from national or other international systems, and schools usually have an entry process to check readiness, such as reviewing past results or meeting with the student.
There may be an adjustment period, particularly around coursework and extended writing, if your child’s previous school focused more on exams. Asking about the support available, such as orientation sessions or regular check-ins with teachers during the first term, can help everyone feel more prepared for the change. It also gives you a clearer picture of the first few months.
A Few Terms You’ll Hear Often
IB schools use some terms that can sound unfamiliar at first. Here are a few you may hear on school tours or at parent meetings:
| Term | What It Means | When It Comes Up |
| Higher level | Subjects studied in more depth, with more teaching hours. | When your child chooses Diploma subjects. |
| Internal assessment | Coursework marked by teachers and then checked externally. | Throughout both Diploma years. |
| Predicted grades | Teachers’ estimates of final results, often used in university applications. | During the final year, as applications go out. |
If a term affects subject choices, ask staff at IB curriculum schools to explain it in more detail.
Bringing It All Together for Your Family
The IB Diploma is a two-year programme at the end of the IB journey, combining subjects, coursework, a longer research paper and activities beyond the classroom. Students can arrive from the Middle Years Programme or from a completely different system, and schools generally have ways to help them settle in.
Understanding the basics makes conversations with schools far more productive. Once you know where the Diploma fits and what the common terms mean, you can focus your questions on what matters most for your child, such as subject choices, the support on offer and how the workload is balanced across the two years.
