Selecting the right academic pathway after GCSEs is one of the most important decisions you will make for your child. While A Levels remain the most common option in London, many schools now offer an alternative that has gained global recognition: the International Baccalaureate Diploma.
At first, the structure can feel confusing. Students study six subjects instead of three, the grading system uses points rather than letter grades, and coursework plays a larger role in assessment.
And you might be asking: Is the IB the right choice for my child?
There’s no need to feel overwhelmed.
This guide explains what the IB Diploma Programme is and how it works in practice. It also covers what London families should consider before choosing it, how the points system operates, which schools offer the programme, and where students often need extra support.
The IB Diploma Programme is a two-year academic qualification for students aged 16 to 19. It was designed to prepare them for university learning by promoting analytical thinking, research skills, and interdisciplinary understanding, which are important for higher education.
Unlike many post-GCSE pathways that encourage early specialisation, the IB keeps students engaged with multiple academic disciplines at the same time. Languages, sciences, mathematics, and humanities remain part of the curriculum throughout the programme.
Many universities across the UK and internationally recognise the qualification, such as Oxford, Cambridge, and many Russell Group universities.
The programme is built around six academic subjects and three core components. This creates a balance between subject depth and intellectual breadth.
Students usually select one subject from each of the following groups:
Some schools also allow students to replace the arts subject with an additional science, language, or humanities course.
The programme further combines three Higher Level (HL) subjects, studied in more depth, with three Standard Level (SL) subjects, which provide a broader understanding across other disciplines. HL courses involve roughly 240 teaching hours, while SL subjects involve about 150 hours.
Language learning remains central to the programme. Many students take IB English within the Language and Literature group, where they analyse literary texts, examine global issues through language, and practise advanced essay writing. These analytical skills further prepare students for the academic writing and research expected at university.
Alongside the six subjects, students must complete three additional components that make up the IB core points, which contribute to their overall diploma score.
Two of the most prominent points are Theory of Knowledge (TOK) and the Extended Essay (EE).
The third element is CAS (Creativity, Activity, Service). Students take part in creative projects, physical activity, and community service throughout the programme. While CAS doesn't directly award points, students must complete it to earn their diplomas.
As mentioned earlier, the IB uses a points-based grading system rather than letter grades. Each of the six subjects is graded from 1 to 7, with 7 representing the highest achievement.
The conditions below form the official IB Diploma Requirements, which include passing core elements and avoiding very low scores in Higher Level subjects.
For reference, UK universities often interpret IB scores approximately as follows:
Since it’s natural to draw comparisons between the IB and A Levels as a parent, we’ve presented an insight below to help you deduce which route is the most suitable.
Students who want to specialise early prefer A Levels. Meanwhile, those who enjoy studying multiple subjects simultaneously benefit from the broader IB curriculum. To decide between the two, make sure to prioritise your child’s preferences and interests.
Thinking about which London schools to select for IB? Don’t worry, we’ve listed the top institutions below that offer the IB Diploma.
If your child’s current school doesn’t offer the programme, you can change the institution or also prepare as a private candidate with additional academic support.
Despite its strengths, the IB programme can be challenging, and your child may struggle to manage all subjects, keep up with coursework, or meet research requirements.
The most common struggle factor is balancing multiple academic disciplines at once. However, with consistent organisation and effective study habits, this can be resolved.
Most IB subjects include internal assessments or research projects. Students have to complete these alongside exam preparation, which ends up overburdening them. The best way to resolve this is to break tasks into smaller and manageable steps and follow a weekly timetable to keep up with assessments and revision.
The Extended Essay requires students to conduct long-form academic research. For many, this is their first experience of developing a research question and forming a structured academic argument. You can advise your child to get guidance from a tutor or mentor to plan their research question and essay outline before they start writing.
Although the costs of the IB programmes depend on the level of support students require, we’ve provided a general average estimate table below for clarity.

The IB Diploma Programme helps your child develop academic curiosity, critical thinking, and research skills. Students who complete it develop strong writing and time management skills, which are important for progressing in advanced coursework.
As a parent evaluating post-GCSE options, you can take time to thoroughly understand how the programme works and determine whether it suits your child's learning style and long-term goals.
Overall, with careful planning and the right support, your child can meet the demands of the IB and master the skills that are helpful for higher education.
However, if you’re looking forward to exploring private support options, HRB Education is here to help. Our specialised tutors guide and prepare students for exams, essay writing, and research planning through a personalised curriculum. This approach lets them manage the IB workload and achieve excellent results.

The IB Diploma Programme is a 2-year international qualification for students aged from 16 to 19. It combines six academic subjects with research, critical thinking, and community engagement activities.
The IB Diploma programme is usually considered hard because students are required to manage six subjects simultaneously. Additionally, they must complete their coursework and research projects and prepare for the examinations.
Yes. GCSEs are Level 2 qualifications, while the IB Diploma is a Level 3 programme comparable to A Levels. It requires in-depth analysis, research writing, and self-study.
The 5 hardest IB subjects are generally Higher Level Mathematics (Analysis & Approaches), Physics, Chemistry, History, and Further Mathematics, due to content difficulty and exam demands.
