Exclusive: Leading critic of Ofsted's reliability admits watchdog now 'doing well'
Professor Robert Coe, who previously called for inquiry into the reliability of Ofsted inspections, says that results of recent trials are 'quite good'.
A finding that 10 per cent of Ofsted inspections are unreliable is no cause for alarm, according to a leading assessment expert.
Robert Coe, director for the Centre for Evaluation and Monitoring at Durham University, said: “On the face of it, I don’t think it sounds dreadful. In fact, it sounds quite good to me.
“The reality is that this is a subjective judgement process – you’re not going to have 100 per cent agreement. The reality is that we’re going to have to live with some misclassification or subjectivity.”
