like most of the uk, derby operates a non-selective primary and secondary education system with no middle schools. pupils attend infant and junior school (often in a combined primary school) before moving onto a secondary school. many of the secondary schools have sixth forms, allowing pupils to optionally take a levels after the end of compulsory education. for those who want to stay in education but leave school, the large derby college provides post-16 courses for school leavers, apprentices and employer related training. it has two main campuses the joseph wright centre in the centre of derby, where its a level courses are based. and the historical derby roundhouse which is the college's vocational training hub, providing a centre for apprenticeships such as engineering, catering and hair & beauty. the college also works in partnership with schools across the county to provide vocational training opportunities for students aged 14 upwards. training for companies is undertaken through its corporate college.
