About grade boundaries

Grade boundaries show the minimum number of marks you need for each grade, and are published on results day.

Once all exam papers have been marked, grade boundaries are set by senior examiners and assessment experts. It’s not until after all the marking has been completed that it’s possible to see how difficult students found the paper (for example, compared to previous years) and so take this into account when setting the boundaries. This means that a student who performed at a certain level should get the same grade regardless of which year they sat the exam.

Ofqual will offer more generous grading of exams this year compared to a normal exam year - learn more about grading as part of exam changes in 2022.

Notional grade boundaries for components

Students are given a single overall grade for a subject, which is based on a single overall subject mark and the subject grade boundaries.

However, we are able to provide ‘notional grade boundaries’ for individual components of the qualification (for example, a question paper), for illustrative purposes only. Although there are no official grades for individual components in linear qualifications, notional grade boundaries can be useful for students and teachers to see how the overall subject grade was achieved. Download the guide below for more information on this.

Raw mark grade boundary tables map raw exam marks to grade boundaries.

Qualifications that use uniform marks can't be used with these tables (the results slip will show the UMS mark).
