There are three main entry points to Radnor House; Year 5 into the Junior School, Year 7 into the Senior School and Sixth Form.

Year 5 - Junior School

The main intake into the Junior School is at Year 5. We would advise parents to apply at least one year prior to entry. The entry procedure for Year 5 is via a short English and Maths assessment and a classroom-based activity, subject to change due to Covid 19 guidelines.

One class with approximately 20 places is available to girls and boys following a successful performance in the assessment. 

Pupils who join us in Year 5 will not require further assessment to join the Senior School in Year 7 as they have already passed the entrance criteria at 9+

The main intake into the Senior School is at Year 7 with approximately 46 external places available to create a cohort of around 66 children. 

Entry to Radnor House is via the 11+ examination process and applicants must apply by the deadline published in the year prior to entry. Places are offered subject to the successful completion of the entrance procedure, please click the link below for further details.
