Overview of Cambridge Assessment International Education
Cambridge International examinations are part of the University of Cambridge, offering qualifications that prepare learners for life, not just exams. The grading system is structured to:
- Ensure fairness across different schools and countries.
- Provide recognition by universities and employers worldwide.
- Measure not only content knowledge but also application, analysis, and problem-solving skills.
Grading System for Cambridge IGCSE
The International General Certificate of Secondary Education (IGCSE) is taken by students aged 14 to 16.
- Grades: A* (highest) to G (lowest).
- Performance: A*–C are considered strong passes; D–G are lower pass grades.
- Percentage Uniform Marks (PUM): Shows how close a student is to the next grade boundary, offering a more detailed performance picture.
IGCSE grading is designed to reflect a wide range of abilities, helping schools support both high achievers and learners who need more foundational support.
Grading System for Cambridge O Level
Cambridge O Level is equivalent to IGCSE but offered in specific regions.
- Grades: A* to E.
- Comparison to IGCSE: O Level grading scale is slightly narrower, focusing on regional education standards.
- Recognition: Accepted by universities and employers just like IGCSE.
Grading System for Cambridge International AS & A Levels
These qualifications are typically taken by students aged 16 to 19 and prepare them for university.
- Grades: A* (highest) to E (minimum pass).
- A Award:* Only available at full A Level, not AS Level.
- Assessment Style: Emphasizes depth of knowledge, critical thinking, and independent learning.
UCAS Tariff Points
In the UK, A Level grades translate into UCAS points, which universities use for admissions. For example:
- A* = 56 points
- A = 48 points
- B = 40 points

How Cambridge Ensures Fairness in Grading
Cambridge uses a combination of statistical evidence and expert judgment to maintain grading consistency.
- Grade boundaries are reviewed annually to account for difficulty levels in different exam sessions.
- Examiner standardization ensures marking reliability.
- Percentage Uniform Marks (PUM) give students more transparency on their performance.
This system ensures that grades remain fair and comparable across years and regions.
