If Your Students Are Heading into the IB Diploma Programme, This Is Worth Reading.

School Leaders, IB Coordinators, and Heads of Mathematics: I believe one of the most important examinations for IB Diploma Mathematics students happens before they ever enter the Diploma Programme.

As an IB Diploma Mathematics examiner, I often get asked what the most important mathematics exam is for a student.

Most people expect me to say the final IB Diploma Mathematics examination.

I don’t.

I think one of the most important mathematics examinations a student will ever sit is their Grade 10 examination.

Here’s why.

Mathematics is one of the few IB Diploma Programme subjects for which the IB publishes a list of prior learning topics. The Diploma Programme doesn’t start from scratch. It assumes that students already have a solid understanding of algebra, functions, trigonometry, geometry, statistics, and a range of other fundamental concepts before they enter Grade 11.

What I’ve noticed over the years is that many schools become understandably focused on criteria, rubrics, ATL skills, and reporting. These are all important parts of an IB education.

But sometimes the curriculum itself gets less attention than it deserves.

The students who find IB Mathematics manageable are not always the smartest students in the room. More often, they are the students who arrive in Grade 11 with strong foundations and good mathematical habits.

The students who struggle are often not struggling because the Diploma Programme is too difficult. They are struggling because gaps from earlier grades start to catch up with them.

That’s why Grade 10 matters.

A strong Grade 10 performance is usually a good indicator that a student is ready for the pace, rigour, and abstraction of IB Diploma Mathematics.

The final Diploma Programme examination may be the one that universities look at.

But the Grade 10 examination is often the one that tells you whether a student is truly prepared for what comes next.

The good news is that some exciting changes are happening within the MYP that will help strengthen the transition between the MYP and the Diploma Programme. The focus on curriculum coherence, progression, and evidence of learning is moving in a very positive direction.

If you are a school leader, IB Coordinator, or Head of Department, it may be worth considering an end-of-year cumulative assessment in Grade 10, preferably one that is externally assessed or benchmarked. Such assessments can provide valuable evidence of students’ readiness for the Diploma Programme and help identify gaps before they become barriers to success in Grade 11.

The earlier we identify those gaps, the better chance we have of helping students bridge them.
