Basically as above. I'm also not Ofsted before I get a flaming from teachers;)
It's a government funded role, I have a DBS so often wondering around by myself and teachers rarely put on a show. It's in an educational role just for year 10/11s.
My schools are varied from £30,000 A year to failing - rural to urban to grammar and SEN.
To kick things off my first observation is that state schools usually have better facilities than those in the private sector.
