My personal view on all this is not that the schools in question have been targetted by radical groups but that situations have developed due to circumstances, perhaps inevitably.

I do believe that these schools are likely to have performed rather well academically, that the original Ofsted reports that rated some as Excellent were probably spot on as far as academic achievement was concerned. I know in the area I live that a Muslim school has often been the top performer in the achievement tables.

So, take a school where 90 plus percent of the pupils are Muslim, from Muslim families and communities; you don't have to introduce an agenda of Islamification for the school to slowly but surely edge in that direction. Girls & boys discouraged from close interaction, prayer encouraged, the teaching of Islam taking precident over other faiths. The kids are going home to communities where all these things are upheld and encouraged, it's almost inevitable that such a school will show signs of practices that may be regarded as inappropriate in a secular educational establishment.

Now whether some members of the community have taken advantage of this and found a path of little resistance to impart their own ideologies; on boards of governors or other influential positions, perhaps this is the case; but I'd suggest much of what we see is a natural occurance which has developed because we haven't been looking for it, it has been out of focus.

Now is the time to bring things back into focus and proceed as appropriate.
