RM Compare is an online tool that facilitates a highly accurate and efficient way of ranking and grading work, removing the need for traditional marking and moderation.

RM Compare harnesses the power of adaptive comparative judgement, allowing teachers or students to review two pieces of work at a time side-by-side and identifying which is best (in relation to the assessment criteria or learning goal). Through multiple rounds of this anonymised 'pairwise marking' across multiple judges, a highly reliable rank order is established of submitted work based on professional consensus.

RM Compare has been successfully used across networks of schools as well as for peer-to-peer assessment at Universities both in the UK and USA.
