We use Comparative Judgement to provide a detailed understanding of our students’ writing. The assessments are nationally standardised and our insights are based on over half a million pieces of writing.

Comparative Judgement assesses open-ended work more reliably than traditional marking.
Comparative judgement is a process where judges compare two responses and decide which is better. Following repeated comparisons, the resulting data is statistically modelled and responses placed on a scale of relative quality. 
Research has shown the process to be as reliable as double marking, but much quicker.
