The Compton School is an above average size secondary school for pupils aged 11 to 16, situated on the outskirts of Brampton, a town in the West Midlands. Unemployment in the area has risen following a decline in motor manufacturing. In a letter to the local newspaper an angry parent was critical of the quality of education being provided by the school. The parent alleged his son was unable to learn because lessons were disrupted by poor behaviour and argued that this was the reason why the schools test and examination results are below national averages and well below those of most other schools in the area. It is also known that: Over the last six years the school has had three different headteachers. Two years ago a large part of the school was burnt down and many lessons take place in temporary classrooms while rebuilding work is going on. There are 1,200 pupils in the school, of whom 58 per cent are boys and 42 per cent are girls. The staff are coping well with the disruption being caused by the rebuilding work. The school was last inspected four years ago and judged to be providing a satisfactory quality of education at that time.
