Unverifiable student work: Teachers can't tell who learned and who prompted
Most institutions are writing or planning a policy about AI; few have changed what they actually measure. The essay, the problem set and the report were proxies for thinking that worked only while producing them was expensive. That assumption is gone. Detection tools are unreliable enough to risk accusing the wrong students, and much of what is graded no longer shows reliably what a student understands.
Teachers and lecturers redesigning assessment alone · students wrongly suspected · institutions whose credentials depend on the answer
Why now
A UNESCO survey found 19% of higher education institutions had formal AI guidance with a further 42% developing it, while more than half reported uncertainty about how to apply AI pedagogically and one in four had already encountered ethical problems including authorship disputes.
Why it matters
The question has moved from catching misuse to evidencing learning, and nothing is built for the new question. Making a student's reasoning visible, cheaply and without treating them as a suspect, solves what detection never could.
From public reporting
Framed from public reporting. Here is what it was drawn from, so the framing can be checked against it:
Work it through with Ainna and it is packaged as finished documents: a problem framing document and deck, a pitch deck, a PRD and more. See the document examples
Take it to a hackathon
Use it as a challenge statement: copy it as a brief with who it affects, why now and the evidence to start from, ready for your event page. More hackathon problem statements on the Index.

Problem Radar listens to public reporting, from institutions, research and the press, for problems worth solving, and frames each one to the same standard; Ainna's innovation team chooses and edits every problem before it goes on the Index. Every problem says where it came from, so the framing can be checked. Nothing on the Index comes from a user, and what you bring to Ainna is never published. How Problem Radar works.
Students choosing what to study need a fair picture of the work their degree leads to. The evidence they are given describes an earlier market. Official long-run earnings figures, and the rankings that use them, follow graduates who started work before generative AI. Government job forecasts are built on historical patterns, and their authors warn against reading them as predictions. School advisers are stretched, and the people building AI contradict one another in public on what to study. Meanwhile employers are redesigning entry-level roles in AI-exposed occupations, and some students are already switching subjects because of AI, before the evidence settles. The choice comes early, costs years and often debt, and is hard to undo. It stays unsolved because the current evidence is unsettled, the trusted evidence is old, and the two reach students separately.

Loss happens at the handovers: field to packer, packer to distributor, distributor to shelf. Every party measures only its own side of each one. So each set of numbers looks defensible while the total is enormous, and the interventions that would work are precisely the ones nobody can see, because they sit between two businesses rather than inside one.
Before a hospital or clinic can use an AI tool, the tool is tested and approved. That happens once. Afterwards, the rules mostly wait for someone to report that something went wrong. But an AI tool does not stay the way it was tested. It gets updated. It behaves differently with real patients than it did in the test. And it can work well in one place and less well in another. So a single test, done once before the tool went into use, cannot tell you whether it is still safe where you are treated today. What is missing is a way to keep testing it while it is in use, to update it carefully, and to help hospitals and clinics see for themselves how it is doing.
