GCSE Combined Science: new grading system

Since 2019, GCSEs will be graded between 9 and 1. GCSE Combined Science students will receive a double grade on a 17-point scale, from 9-9 to 1-1.

This double award is worth two GCSEs, and is made up of two equal or adjacent grades. There are 17 possible grade combinations, for example, (9-9), (9-8), (8-8), (8-7) – through to (1-1).

Grade boundaries

The method used to set the grade 9-9 boundary for GCSE Combined Science is similar to the one used to set the grade 9 boundary for the first 9 to 1 GCSE results in 2017, but adapted for the double grade.

Generally, a student who would have got an average grade A across science and additional science in 2017 would get grade 7-7 in GCSE Combined Science from 2018 onwards.

In summer 2018 Ofqual introduced a new allowed grade 3-3 for combined science, and a full-width safety net grade 4-3 on combined science. They also allowed a full-width grade 3 in separate sciences. Ofqual have said that they will not repeat these special arrangements in 2019. You can read more about this on Ofqual’s blog published on 15 January 2019.
