Whatever assessment policies say, the unsupervised take-home essay as a test of unaided student writing is gone. The institutional response has been retreating. The universities of Melbourne and Toronto are phasing out unsupervised take-home essays. The University of Cape Town’s AI working group wants 40% of assessments invigilated by 2027. At Durham University, a professor of philosophy stood down as chair of his board of examiners, citing a marking crisis. But retreat is only one of three institutional responses now visible worldwide, and comparing them is instructive. The second response, arguably the least defensible, is detection-led enforcement: running submissions through AI detectors and prosecuting the flagged. This approach is quietly collapsing.
