Education in Northern Ireland differs from systems used elsewhere in the United Kingdom, although it is relatively similar to Wales. A child's age on 1 July determines the point of entry into the relevant stage of education, unlike England and Wales where it is 1 September. Northern Ireland's results at GCSE and A-Level are consistently top in the UK. At A-Level and BTEC level 3, one third of students in Northern Ireland achieved A and distinction grades in 2007, which is a higher proportion than in England and Wales.
