Educators and research organisations can set their own tasks and use Comparative Judgement for internal assessments and research projects.
Accuracy
Research consistently finds that Comparative Judgement delivers the accuracy of double or triple marking in a similar time or less than single marking.
Validity
Teachers make holistic judgements based on the overall quality of the writing. We combine together thousands of teacher judgements with AI judgements to create a highly reliable scale of writing.
Anonymised assessment
We provide Optical Character Recognition sheets for pupils to write on. When you upload the sheets the pupil names magically disappear, but they will still be matched to your data.
Robust data controls
Every judge's performance is recorded, and decisions made by unreliable judges can be removed from the results.
