Your IB versus A Level Grades Comparison Guide
So how do IB Grades translate into A Level Grades and UCAS Points as part of UK university entry requirements?
The IB Diploma offers a unique grading system that evaluates not only your subject knowledge but also skills like critical thinking and research. This guide breaks down the IB grading scale, shows how IB points translate to A Level grades, as well as UCAS Tariff Points, and what these scores mean for your university applications, so you can confidently plan your path forward.
What is UCAS, and Why Do Points Matter?
UCAS (the Universities and Colleges Admissions Service) is the organisation that manages university applications in the UK. UCAS points, often called “tariff points,” provide a measure to compare different types of qualifications, including the IB and A-Levels, making it easier for universities to assess students on the same scale.
It’s important to note that UCAS tariff points are only used by some universities (around than a third) when making conditional offers. Instead of asking for grades (e.g. ABB), a university may express the offer in the equivalent tariff points. Most universities do not use tariff points. This applies especially to more traditional universities, who are more likely to make an offer stipulating grades and not points.
How the IB Grading System Works
The IB Diploma Programme uses a unique 1-7 grading scale per subject, where 7 is the highest grade achievable. In addition to studying six subjects (three at Higher Level and three at Standard Level), the IB includes three core components: Theory of Knowledge (TOK), the Extended Essay (EE), and Creativity, Activity, Service (CAS). These core elements add depth to your education, and TOK and the EE can contribute up to 3 extra points, making 45 the maximum IB score.
IB vs A Level Grades & UCAS Tariff Points
Here’s a breakdown of IB scores, UCAS tariff points, and how they align with A-Level grades:

For example, if a university requires AAA at A-Level, an IB score around 36 usually meets that standard. For a points-based offer, aiming for around 36 IB points can satisfy many competitive course requirements.
The 2024 global average at Westbourne is 38 Points, at Westbourne Sydney it is 39 Points.
Why Do Universities Value IB Diploma Scores?
Universities often appreciate IB graduates for their research skills (developed through the EE), critical thinking (cultivated in TOK), and global perspective (promoted by CAS). These qualities make IB students well-prepared for the challenges of university. Research from the Higher Education Policy Institute suggests that IB students are more likely to earn first-class honours degrees than their peers, highlighting the long-term benefits of the IB’s structure.

Boosting Your UCAS Points with IB Core Components
Your UCAS points in the IB can increase with strong scores in TOK and the EE. Here’s how to maximise your potential:
- Focus on Core Components: Excelling in TOK and the EE can earn up to 3 extra points, a significant boost for your UCAS total.
- Choose HL Subjects Wisely: Selecting Higher Level subjects that play to your strengths can help you reach higher grades.
- Utilise CAS: While CAS doesn’t directly affect UCAS points, it builds experiences that strengthen personal statements and applications.
Planning Your University Path with UCAS Points
Understanding how IB grades and A Level grades translate to UCAS points helps you set clear goals for university entry, whether your offer is points or grade-based. The IB Diploma’s holistic approach prepares you with both knowledge and practical skills, making you a strong candidate for UK and international universities, whilst A Levels encourage specialism in subjects of your choice.
Summary: Top 10 Key Points to Understanding IB Grades
Here’s a concise summary of the top 10 points to keep in mind when thinking about IB Grades vs. A Levels and what this means for university admissions.
- 1-7 Grading Scale: IB subjects are graded on a scale of 1 to 7, with 7 being the highest achievable grade, representing exceptional achievement.
- Total Score: The total IB Diploma score is out of 45, combining subject grades with up to 3 additional points from the Theory of Knowledge (TOK) and the Extended Essay (EE).
- Global Standardisation: The IB grading system is globally standardised, ensuring that grades are consistent and fair across different countries and schools.
- Comprehensive Evaluation: IB grades are determined through a mix of internal assessments (IAs) and final exams, offering a holistic assessment of students’ skills and knowledge.
- Core Components: The Extended Essay and Theory of Knowledge are integral to the IB, contributing additional points to the total score and encouraging critical thinking and research skills.
- CAS Requirements: While not graded, the Creativity, Activity, Service (CAS) requirement is essential for Diploma completion, emphasising personal growth and engagement with the community.
- UCAS Points Conversion: IB grades can be converted into UCAS points, crucial for students applying to universities in the United Kingdom.
- IB vs. A-Levels: IB grades offer a broad, globally recognized qualification, often compared to A-Levels for UK university admissions, with specific IB scores equating to A-Level grades.
- Subject-Specific Grading: Average grades can vary significantly by subject, reflecting the unique challenges and learning outcomes of each course.
- Strategic Subject Selection: Choosing Higher Level (HL) and Standard Level (SL) subjects strategically can maximise grade potential and align with university and career aspirations.
Understanding these key aspects of IB grades provides students and parents with the insight needed to navigate the IB Diploma programme successfully.
With a focus on both academic excellence and personal development, the IB prepares students for higher education and beyond, equipping them with the skills and knowledge to thrive in a rapidly changing world.
