In 2015 an inspector revealed that inspection judgements can be arbitrarily over-ruled by senior figures, commenting on a case where a school had been downgraded: "We couldn’t understand this rationale at all. It turned out that Ofsted had made a brief visit to the school some time before the inspection and had come up with some sort of unreported provisional judgement. So all that evidence we had gathered meant nothing and essentially this team of experienced inspectors was not trusted to make a judgement.” Barton concluded his article, 'the accounts above reveal an inspection system that appears in too many cases to be doing great damage. My sense is that it’s time to stop quietly accepting that the way Ofsted is is the way Ofsted should be.' In response, Wilshaw attacked Barton for being "too quick to perpetuate a 'them against us' view of the schools inspectorate...we fall back on a 'clichéd defence-mechanism' of whingeing about inconsistency", and insisted that Ofsted was becoming "more rigorous and demanding." However, Barton argued the letter lost some of its force and all of its credibility for being published on the day 40% of inspectors were sacked for not being up to the job.
