Several major Ofsted reports are due to be published about the so-called "Trojan Horse" schools in Birmingham which are alleged to be at the centre of a plot to "Islamise" schools (Six schools criticised in Trojan Horse inquiry, 2 June).
The reports will be a landmark in British educational history and the history of Britain as a multi-ethnic and multi-religious society, for better or for worse.
First-hand accounts of the Ofsted inspections that have emerged are disturbing. They suggest that inspectors were poorly prepared and had an agenda that calls into question Ofsted's claim to be objective and professional in its appraisal of standards in schools serving predominantly Muslim pupils.
Numerous sensationalised leaks have reinforced the perception of a pre-set agenda. It is beyond belief that schools which were judged less than a year ago to be "outstanding" are now widely reported as "inadequate", despite having the same curriculum, the same students, the same leadership team and the same governing body. In at least one instance, these conflicting judgments were made by the same lead inspector. This has damaged not only the reputation of the schools but the integrity of the inspections process.
This is uncharted territory, with Ofsted seemingly being guided by an ideology at odds with the traditional British values which schools are meant to espouse, particularly fairness, justice and respect for others. We, the undersigned, believe that such an approach compromises not only Ofsted's impartiality but also the British education system itself.
We call upon the government to reject such tarnished inspection reports and seek a more transparent process of inspections which truly places the education and wellbeing of the children of Birmingham foremost.

• Surely Ofsted is losing all credibility (Leak reveals inspectors' U-turn on 'Trojan Horse' school, 31 May). Increasingly it appears to be used as Michael Gove's enforcement. This is not the first time Ofsted judgments have been rejigged, as many schools forced into academy status against the will of communities and parents can attest. In this process Ofsted's framework for the inspection of schools is revealed as flawed. Judgments of good and inadequate schools are unreliably based on test and examination results. Until Park View it was unacceptable to judge a school as inadequate, or for that matter to judge the quality of teaching as poor, if the examination and test results were good.
Further, the inspection of Park View must again throw some doubt on the competence of inspectors. In 2012 it was revealed that some inspectors had no experience of working with children and were not qualified teachers. Ofsted's methods are not the objective process that has been assumed and are clearly subject to manipulation.
