Update on moderation sample size for internally assessed work

20 October 2025
Dear colleague,

From the January 2026 series, for Project and BTEC Tech Award qualifications we’ll be asking for a larger sample size when moderating internally assessed work.  

From June 2026 onwards this approach will also apply to GCSE, International GCSE, A level and Entry Level Certificate qualifications.

We’re making this change because, from time to time, moderators need to request additional samples to complete their moderation. When these requests come later in the year, we know it can be challenging for you to manage alongside the demands of a busy series.

By asking for a slightly larger sample upfront, we aim to make the process smoother and reduce the likelihood of additional requests later on. This should help us complete moderation more efficiently, and give you and your students greater clarity and confidence in the outcomes. This process will not affect the way in which moderators currently review the sample, and they will only look at additional samples of work where needed.
