All schools in the secondary sector of Newcastle's educational provision have now been reorganized, apart from the six Roman Catholic secondary moderns and one Roman Catholic secondary technical school. A breakdown of the secondary school population shows that, of some 14 800 children, 13 000 are grouped in large comprehensive units. Eight of these are co-educational, and the remaining two single-sex schools (one boys' and one girls'). The six Roman Catholic secondary moderns have a role of from 150 to 270 pupils, the largest denominational unit being St Mary's Technical School with about 500.
