Are more students cheating on assessment tasks in higher education? Despite ongoing media speculation concerning increased 'copying and pasting' and ghostwritten assignments produced by 'paper mills', few studies have charted historical trends in rates and types of plagiarism. Additionally, there has been little comment from researchers as to the best way to assess changes in plagiarism over time. In this paper we discuss the relative strengths and weaknesses of research designs for assessing changes in plagiarism over time, namely: cross-sectional, longitudinal, and time-lag. We also report the results of our own time-lag study of plagiarism. We assessed self-reported engagement in, awareness of, and attitudes toward plagiarism in three comparable groups of students at the same university on three occasions, each separated by 5 years (2004, 2009, and 2014). The data from our study paints an encouraging picture of increased understanding and reduced occurrence of several forms of plagiarism, with no upward trend in verbatim copying or ghost writing. We suggest that technological and educational initiatives are counteracting the potential for increased plagiarism from online sources.Keywords: Plagiarism, academic integrity, cheating, ghost writing, trend, time-lag, longitudinal Is plagiarism changing 3 Recently in Australia (e.g., 2014Australia (e.g., -2015 there have been several dramatic and shocking reports on serious breaches of academic integrity. A prominent scandal was the discovery of the MyMaster paper mill, which provided customwritten assignments, mostly to Chinese-speaking students, at a number of universities across Australia (McNeilage & Visentin, 2014). This was followed by the Independent Commission Against Corruption's (ICAC, 2015) report into accusations of widespread cheating, particularly by international students, in Australia. Soon after, an internal report from the University of Sydney uncovered numerous instances and forms of academic misconduct among students. Among the documented breaches and allegations were instances of ghost writing, fabrication of data, and students employing others to sit exams in their place (Smith, 2015). Of course, such concerns and anecdotes are not limited to Australia and instances of, and responses to, plagiarism remain a serious concern for higher education globally.Revelations such as those in Australia always raise the question in the media 'Is cheating at university on the rise?'. Such media stories inevitably suggest that cheating has been facilitated by the internet, where students can easily copy and paste electronic content, and make contact with paper mills and ghost writers. However, such stories often neglect the balancing effects that technology has afforded in counteracting academic misconduct (Park, 2003). To be sure, over the past decade the internet has afforded students increased and unique opportunities to engage in plagiarism. By the same token, the internet has also provided significant opportunities for universities and academics...
