Business schools mix AI detectors with teacher review for student work

In short: Business schools are using AI detection tools as a first check, then relying on teachers to review work and rethink how students are graded.

What's going on

Business schools are trying to spot when students use AI in ways that break class rules. Many schools now use automated detectors such as Turnitin, and some also use Copyleaks, GPTZero, Originality.ai, and ZeroGPT.

These tools look for patterns that can show up in computer written text, like very even sentence style or predictable wording. They usually return a score that estimates how likely it is that AI helped write the text. Schools and tool makers say these scores are clues, not proof, because results can change depending on the topic, the length of the writing, and how much a student edited it.

Because of those limits, teachers are adding manual checks. They look for sudden changes in a student’s tone or vocabulary, vague arguments that never take a clear position, citations that do not make sense, and missing signs of work in progress, like drafts or revision history. Some also watch for unusually fast turnaround times.

This mix of tools and teacher review is becoming common across higher education. More than 60% of institutions have adopted formal AI detection technology, and nearly two thirds have issued guidance on AI use. Policies vary a lot, and smaller colleges may rely more on human judgment than automated scores.

What to watch

Schools are starting to change assignments so the process matters as much as the final essay, like asking for drafts or version history (a saved record of edits, like a receipt trail). Tools such as Turnitin Clarity point in that direction by letting students use approved AI while giving educators a clearer view of how the writing was produced.
