Grade thresholds explained
We publish grade thresholds after each exam series. A grade threshold is the minimum number of marks that a candidate needs to achieve to be awarded a particular grade in a paper or in a subject. Before you read the grade threshold document, there is some important information you need to know about how we set the thresholds.
How do we set grade thresholds for each component?
We set grade thresholds after each examination has been taken and marked. In each exam series the aim is to set each threshold in the right place so that it is no more difficult and no less difficult to obtain each grade than it was in the previous year.
To achieve this, the thresholds may change from one series to the next. For example, if we find that the questions in a paper have been more difficult than last time, we have to lower the thresholds, or if we find the questions have been easier, we have to raise the thresholds. This is to be fair to candidates from one series to another. The guide and video on this page show how we make sure that all candidates taking our exams receive fair and accurate results.
How do we set grade thresholds for each combination of components?
The grade threshold table shows the thresholds for each component and for each possible combination of components. Each combination of components makes up the overall qualification.
In the simplest cases, the component thresholds are added up to get the threshold for the combination of components.
For some syllabuses we apply a weighting factor to the component thresholds before we add them together. This is so each component matches its weighting shown in the syllabus. We publish the component weighting factors on this page.
A candidate’s syllabus grade is determined by comparing the total number of marks the candidate achieves in all their papers (weighted as specified in the syllabus) with the grade thresholds for their combination of components.
Grade A* does not exist as a component grade. The grade A* threshold for each combination of components is calculated relative to the A and B thresholds for the combination of components and the maximum mark.
