Although universities differ in how they deal with student plagiarism, there are also 'clusters of consensus’. This is the finding of the second phase of the Academic Misconduct Benchmarking Research Project (AMBeR) conducted by the UK's Academy JISC Academic Integrity Service (AJAIS). The report found that while all universities manage the issue of student plagiarism on an individual basis, the most common ways of dealing with the issue were the resubmission of assessments, where the resulting mark would be capped and a formal warning given. Over 50 per cent of the recorded instances of plagiarism were dealt with in one of these ways. The report also indicated that the vast majority of offences are first offences which suggests that current measures being taken are successfully reducing repeat offenders.
