Top All-Through Schools

This table shows the top 10 Prep Schools that are attached to high performing Senior Schools in the London area. The majority of the children that leave these Prep Schools will move on to the attached Senior, therefore the schools are measured according to the GCSE results of pupils in the senior school in 2017.

NOTE: Although these Prep Schools are linked with the Senior Schools, progression is not automatic and the child will need to achieve the required levels to move on to the senior school.  We recognise that a table such as this is not of course the only, nor indeed necessarily the most important indication of a ‘top school’. Equally important is that a prep school prepares each child for the next stage of their educational journey and ensures that they secure a place in the most suitable school. Prep schools which are non-selective on entry and which send children to a wide range of senior schools will be suitable for most children.
