Ticked, Not Tested, Explained

Dagny Okafor, Ingeborg Nwachukwu and Casimir Beng on whether a warehouse's oral food-safety tick predicts what workers still know three months on

A research explainer from the School of Continuous Improvement on Dagny Okafor, Ingeborg Nwachukwu and Casimir Beng's study of the checkbox that closes a warehouse's food-safety refresher. It starts at the oral check itself, a supervisor's two or three questions and the single tick that records them, then sets that tick beside a written retest of nine hundred workers three months on and recordings of the checks themselves. The three authors speak for their own work in turn.
