Accurate and reliable marking is a cornerstone of valid assessment. We carry out a wide range of research into all aspects of marking, from selecting, training and marker standardisation to monitoring marker accuracy and identifying factors which affect accuracy and reliability. As a result, we are able to gain insight into how accuracy, reliability and, indeed, efficiency might be improved.
Our research into on-screen marking established the reliability and validity of this mode of marking. Research into machine marking helps to identify the circumstances in which it might be appropriate to use automated marking techniques, and those in which it is not, given the current state of the art.
