In this paper we argue that comparative judgement delivered by online technologies is a viable, valid and highly reliable alternative to traditional analytical marking. In the past, comparative judgement has been underused in educational assessment and measurement, particularly in large-scale testing, mainly due to the lack of

supporting technologies to facilitate the large number of judgements and judges. We describe the foundations of comparative judgement and dispel many of the old issues regarding its use in regards to time, cost and training for large-scale assessment. Studies in the use of comparative judgement and online technologies for

the assessment and measurement of practical performance conducted by Edith Cowan University provide a context for further promoting its use in educational testing.
