How to Prevent Cheating on Online Exams

Layer one: design the assessment to resist assistance

Questions that require reasoning about course-specific material, in-class artifacts, or a student's own prior work are substantially harder to outsource than recall questions. Randomized item banks and tighter windows reduce answer sharing, and short oral follow-ups on high-stakes items raise the cost of assistance considerably.

Design alone will not carry a high-stakes assessment once a hidden assistant can run on the same machine, but it removes the easiest opportunities and narrows what enforcement has to cover.

• Prefer applied reasoning over recall on high-weight items.
• Use randomized item banks and per-student ordering.
• Keep high-stakes weight on proctored or verified components.
• Add brief oral or follow-up verification where the stakes justify it.

Layer two: state the rules before the session

Ambiguity is what makes academic-integrity cases painful to resolve. Publish, per assessment, which tools are permitted, what is monitored, how long session data is retained, and what happens when a session is flagged. Students who know what is observed behave differently, and institutions that disclose clearly are in a far stronger position at appeal.

Why browser-based tools cannot see the assistance

Browser extensions and lockdown browsers observe the page, the tab, and often the webcam. Their visibility ends where the browser process ends, and that is precisely where modern AI assistance lives.

Desktop assistants and answer overlays render above every other window, are frequently excluded from screen capture and screen sharing, and never interact with the assessment tab. Remote-control tools, virtual machines, injected keyboard input, and a second device off camera are equally invisible from inside the browser.

• Native overlay applications draw over the assessment and are often excluded from screen share.
• Remote-access tools allow another person to drive the machine with no browser-visible trace.
• Virtual machines let the assessment run inside a controlled environment with helpers outside it.
• Injected or synthesized keyboard input can enter answers that were never physically typed.
• A second phone, tablet, or monitor off camera leaves nothing at all in the browser.

Language is deliberately factual rather than accusatory, because the institution or employer makes the decision, not the software. Reports export to PDF and can be shared through a secure link for academic-integrity hearings, HR reviews, and compliance audits, with configurable retention including zero-retention operating modes.
