Universities have various ways of handling student assignments. Some universities hold onto student assignments for several years, using them for plagiarism detection and to prevent contract cheating, where students pay someone else to complete their assignments. Other universities dispose of student assignments after a certain period, usually 2-4 semesters past the original course, in secure disposal bins. With the increasing use of AI, universities also need to detect AI-generated content in student assignments to ensure academic integrity. This is done through a combination of strategies, including the use of AI detection tools and human expertise to identify patterns in text that indicate machine generation.

What You'll Learn
How long universities retain student assignments
The duration for which universities retain student assignments varies across institutions and departments. While there is no one-size-fits-all answer, some common practices and guidelines can be identified.
Instructors and course convenors are often required to keep student assignments and exams for a specific period, usually lasting a few semesters after the original course. This allows for potential grading challenges and disputes. After this period, the work is typically disposed of securely.
For example, at the University of Richmond, instructors' materials remain in Blackboard courses for five years after the last day of the semester. However, all student information in a Blackboard course becomes unavailable 60 days after the semester ends. The University of Richmond's policy also specifies that grades are deemed correct unless notified otherwise within three months after the close of the term.
The duration of retention can also depend on the format of the assignments. If assignments are saved in soft copy format or submitted through online tools, they may be preserved indefinitely, especially if stored on university servers or platforms. On the other hand, some universities dispose of hard copies of assignments after a certain period, usually within a few semesters.
Additionally, plagiarism detection software like Turnitin stores student papers indefinitely. These databases contain billions of student papers, academic books, archived web pages, and other sources to facilitate plagiarism checking for educational institutions.

Using student assignments for later research and plagiarism detection
Universities use student assignments for research and plagiarism detection in a variety of ways. Firstly, they may retain student assignments for several years, using them as a reference to detect future plagiarism. This is often done with the help of plagiarism detection software such as Turnitin, SafeAssign, and Check-For-Plag (CFP). These software tools compare student submissions to a database of previously submitted assignments, academic books, journals, web pages, and other sources to identify any similarities or copied content.
Additionally, universities are increasingly encountering AI-generated content in student assignments. To address this, they employ a combination of strategies, including leveraging AI detection tools, manual review, and contextual analysis. Educators are trained to recognize AI-specific traits such as an overly formal tone, repetitive phrases, unusual sentence structure, and inconsistencies with a student's past work. Creating unique and personalized assignments that require personal insights or class discussions also helps to reduce the effectiveness of AI tools.
Furthermore, universities may use student assignments to conduct research on academic integrity and plagiarism. They analyze common tricks used by students to bypass Text-Matching Software Products (TMSPs) and develop strategies to improve the effectiveness of plagiarism detection software.
While universities have different policies regarding the retention and use of student assignments, it is clear that they leverage these submissions for research and plagiarism detection to uphold academic integrity and maintain the quality of education.

Preventing contract cheating
Universities and colleges are actively addressing contract cheating through various strategies. One approach is to promote academic integrity by focusing on positive issues and encouraging students to uphold academic values. This involves developing institutional strategies, reviewing policies, understanding student motivations, and re-evaluating assessment practices. Additionally, universities can emphasise the importance of ethical AI usage through workshops and clear guidelines, encouraging students to use AI as a supportive tool rather than a replacement for their own efforts.
To detect AI-generated content, universities employ a combination of strategies beyond software tools. AI text often exhibits patterns like an overly formal tone, repetitive phrases, or unusual sentence structure. Inconsistencies between a student's past work and current submissions can also indicate AI usage. By combining human expertise with AI detection tools, such as Turnitin, universities can more accurately identify AI-generated content.
Assessment design plays a crucial role in preventing contract cheating. Individualised assessments, practical exams, and face-to-face evaluations are more challenging to outsource. Institutions can also block access to contract cheating websites and proactively monitor for suspicious behaviours, such as an unusual number of bid requests from a single user, which may indicate an agency subcontracting work.
To further deter contract cheating, some countries have implemented legal measures. For instance, Australia and New Zealand have made it illegal for third parties to provide academic work to students or advertise such services. These legislative steps reinforce the seriousness of contract cheating and send a strong message about upholding academic integrity.

Detecting AI-generated content in assignments
Universities employ a range of tools, methods, and strategies to detect AI-generated content in student assignments and uphold academic integrity. This is a challenging task due to the rapid evolution of AI tools, but a combination of advanced detection software and faculty training can help institutions address this issue effectively.
One popular option is Turnitin, a widely used plagiarism checker that has recently incorporated AI detection capabilities. Turnitin can identify patterns in text that indicate machine generation and can distinguish between human-written, AI-generated, and AI-refined content. Other AI detection tools like Scribrr, Copyleaks, and QuillBot are also available, offering features such as multi-language support, paragraph-level feedback, and the ability to identify specific AI platforms used. These tools can be valuable in detecting AI-generated content, but they are not 100% reliable, and human expertise is still essential.
Educators play a crucial role in detecting AI-generated content by recognizing AI-specific traits. They look for patterns like an overly formal tone, repetitive phrases, or unusual sentence structure, or inconsistencies between a student's past work and current submissions. Significant improvements in grammar and style without explanation may also warrant further review. Creating unique and personalized tasks, such as referencing specific class discussions or personal reflections, can also reduce the effectiveness of AI tools.
To address the issue of AI-generated content effectively, universities should promote ethical AI usage through workshops and clear guidelines. Updating academic policies with explicit rules about AI usage in assignment submissions and outlining consequences for misuse are important steps. Additionally, revamping assignments to incorporate elements that require personal insight, real-world application, or oral presentations can discourage overreliance on AI.
By leveraging technology, educating students and faculty, and updating academic policies, universities can safeguard academic integrity while encouraging responsible AI usage. The use of AI detection tools should be complemented by manual review and contextual analysis and a focus on promoting originality and creativity in student assignments.

University policies on student assignments
One key area is the issue of contract cheating, where students pay a third party to complete assignments on their behalf. This is seen as a serious issue, as it undermines the value of a university degree and the gatekeeping function of university assessments. Some universities are introducing regulations that prohibit the commissioning of assignments from a third party, with academic offences carrying potential consequences.
Another challenge universities are facing is the detection of AI-generated content in student assignments. As AI tools evolve, universities are implementing strategies to safeguard academic integrity. This includes the use of AI detection tools, manual review, and contextual analysis. Educators are trained to recognize AI-specific traits, such as an overly formal tone, repetitive phrases, or unusual sentence structures, and are encouraged to create unique and personalized tasks that are harder for AI to replicate.
Universities also have varying policies on how long they retain student assignments. Some universities require professors to keep assignments for one semester after completion to allow for grading challenges, while others may keep them for 2-4 semesters. After this period, assignments are securely disposed of, although online assignments saved in softcopy format may be preserved indefinitely.
Plagiarism detection is another focus of university policies, with software like Turnitin storing student papers indefinitely to check for plagiarism. Some universities also use plagiarism software to detect shared code in student projects.
