Academic Results and 11+ – 89% pass rate this year.

It is our aim to ensure that children leave CPS at 11 or 13 with at least one year’s academic advantage over national expectations for children of similar age. In practice many children achieve a greater advantage than this while the least able children in the year will be just about meeting the expected levels of achievement for their age. Children sit entrance tests for a wide number of local independent schools and many sit the Bucks Grammar School selection tests at 11+. We achieve this without becoming anything like a “hot house”.

Approximately half the year group qualify for Grammar School but not all these children will in fact take up their places. Some children transfer to independent schools at 11+ while others transfer at 13+ via Common Entrance. Most children receive an offer from the parents’ first choice independent school at 11+ and at 13+. This is because the school has been carefully chosen to provide the most appropriate academic environment for each child.

As a school we ceased to administer the Key Stage SATs at 7+ and 11+ in 2008. Over the course of a pupil’s career at Chesham Prep School a comprehensive range of formative and summative assessment is used to plot progress and to inform teachers’ planning.   At transfer to secondary school at 11+, 12+ or 13+, we are able to provide teacher assessed National Curriculum levels of achievement.

11+ Results

Parents choose whether to enter their children for the Bucks 11+ tests. Please see the table below for our recent results.  Not all children who qualify for a Grammar School place go on to take up their place, some children remain in the independent sector.
