There is probably little doubt that the analysis of data will play an increasing role in teacher recruitment. I am sure that among the companies involved in the development of such platforms there are many good people with solid beliefs and values, individuals who will want to see these systems used in conjunction with personal connections, interviews, and relationships. In other words, in very humane ways, using the algorithm as a guide, not a decision-maker, and this is where biometric data may prove initially attractive. The question, of course, with all “data-driven” initiatives lies not so much with the intent or even the veracity of the data collected, but with how it is used. Data can too easily become the decision-making tool of lazy convenience and ends up being used in ways never intended. When I consider my teaching colleagues, I recoil at the prospect of viewing them as data points. Someone needs to shout stop.
