among the different counties which used it. Usually, it consisted of three papers: Arithmetic – A mental arithmetic test. Writing – An essay question on a general subject.

In Berkshire and Buckinghamshire it was also possible to sit the test a year early – a process named the ten-plus; later, the Buckinghamshire test was called the twelve-plus and taken a year later than usual. Originally, the test was voluntary; , some 30% of students in Northern Ireland do not sit for it. In Northern Ireland, pupils were awarded grades in the following ratios to pupils sitting the exam: A (25%), B1 (5%), B2 (5%), C1 (5%), C2 (5%), D (55%) and there was no official distinction between pass grades and fail grades. Current practice There are 163 remaining grammar schools in various parts of England, and 67 in Northern Ireland. In counties in which vestiges of the Tripartite System still survive, the eleven-plus continues to exist.

For more information on these, see the main article on grammar schools. Eleven-plus and similar exams vary around the country but will use some or all of the following components: Verbal Reasoning (VR) Non-Verbal reasoning (NVR) Mathematics (MA) English (EN) Eleven-plus tests take place in September of children's final primary school year with results provided to parents in October to allow application for secondary schools. In Lincolnshire children will sit the Verbal Reasoning and Non-Verbal Reasoning. In Buckinghamshire children sit tests in Verbal Reasoning, Mathematics and Non-Verbal reasoning. In Kent, where the eleven-plus test is more commonly known as the Kent Test, children sit all four of the above disciplines; however the Creative Writing, which falls as part the English test, will only be used in circumstances of appeal. In the London Borough of Bexley from September 2008, following a public consultation, pupils sitting the Eleven-Plus exam are only required to do a Mathematics and Verbal Reasoning paper. In Essex, where the examination is optional, children sit Verbal Reasoning, Mathematics and English. Other areas use different combinations.
