The school is co-located with special-school Le Murier in the parish of St Sampson.

Both the original schools have now been transformed into colleges of further education, while their pupils have moved to the newer St Sampson's High.

The report claims that the percentage of St Sampson's High School students who attained five A*–C GCSE grades in 2011 was only 38%.
