Cambridge Nationals are a vocational qualification in the United Kingdom introduced by the OCR Examinations Board to replace the OCR Nationals. These are Level 1 and Level 2 qualifications for students aged 14 to 16 and are usually a two-year course. Students can progress to A Levels, apprenticeships or Level 3 vocational qualifications (National qualifications frameworks in the United Kingdom). OCR is part of Cambridge University Press & Assessment.
