Depending on school for which you are applying, the selection process will vary with some schools doing a one stage exam format and some doing a two stage format.
The first stage of the 11 plus is either a pretest (which is done on a computer) or a paper-based test. If the first stage is a computer pre-test, it will be either an ISEB (Independent Schools Examination Board), CEM (Centre for Evaluation and Monitoring) or UKISET (for overseas candidates) examination. The most popular tests are the ISEB and CEM. These tests are normally sat in October and November. However, this can change, so it is best to check with the schools you are applying to when their assessments are.
If paper-based, the test is likely to be run by GL assessment. This will normally take place in the Autumn term of Year 6 (often quite early in the year).
Similarly to the first stage, the second stage can take on different forms depending on the school to which you are applying. Some second stages include a written Maths and English paper, as well as an interview; others do a ‘creative day’ where children will be asked to work as part of a group to problem solve, create or design something.
It is important to check with the school how they structure the assessment so you can fully prepare. If we can help, please ask!
