The 11-plus (11+) is a test taken by some pupils in England and Northern Ireland in Year 6 (their last year of Primary School) to decide which state school they should attend. The name of the test comes from the idea that it allows entrance to schools from the age of 11 (Year 7). The test is voluntary and only taken by pupils who intend on applying for a place at a grammar school. The 11+ may also be referred to as 'entrance exam' or 'transfer test'. The 4 subjects that are tested in the 11+ are English, Mathematics, Verbal Reasoning (VR) and Non-Verbal Reasoning (NVR).

State grammar schools are over-subscribed at around 70,000 children to 20,000 places. To determine which children will offered a place schools use the 11+ as part of their selection process.
