I heard an article on BBC CWR a little while back that the Department for Education were playing silly buggers with the Siva School, as Ofsted had rated the governing academy trust as inadequate, so DfE told them they had to move to a different multi-academy trust which they (the DfE) specified. A leader of the protest group said they were happy to move to a different Trust, but one of their own choosing, which was also rated as good by Ofsted, and maintained the Sikh ethos throughout all of their teaching. The DfE-imposed one was only about 50% Sikh ethos (as I recall).
I'm not generally a fan of faith schools, and believe that education should be secular, with any faith taught outside school. However, I have a massive amount of respect for the Sikh faith, having been to India on holiday a few months ago, and seeing what they do for the community (e.g. serve 5000 meals a day at one temple, absolutely free, to anyone who wants them (Sikh or not, poor or not), staffed entirely by people giving their time for nothing). Apparently the Gurudwara the Siva School is affiliated to is the biggest provider of free meals to the poor and homeless in Coventry.
