After the visit, if you wish to apply for Year 9 entry, you should complete the Tonbridge Registration Form and return it to the school. The registration fee of £200 is non-refundable. You are advised to register your son by the end of Year 5, since the majority of offers are made in January of Year 6.


Those boys who are registered three years prior to proposed entry are invited to sit the ISEB Common Pretest and attend an assessment afternoon during the Autumn Term of Year 6. A current school report will be requested around this time. Entry is subject to a positive report, along with successful performance in the ISEB Pretest and the assessment afternoon. 


Offers of places are typically sent out towards the end of January.


Top-performing candidates receive an unconditional offer of a place at Tonbridge in Year 9. Others may receive a provisional offer of a place, and will be expected to take part in further competitive assessments, which they need to complete at Tonbridge during the Summer Term of Year 7 in order to receive an offer of an unconditional place. These assessments will examine Maths and English skills.
