The Middle School comprises Years 7 and 8 and provides the ideal introduction to life in the Senior School. Each pupil is in a Tutor Group and has a form tutor who will be with them for their two years in the Middle School. During these two years the tutor helps the pupils to settle in to the School. In particular the tutor will guide pupils in their academic, co-curricular and pastoral life.

In the Middle School there are four Houses. These are Barton, Eastwood, Hawkey and Summers. Each House has a designated Head of House and comprises of four tutor groups – two in Year 7 and two in Year 8.

Pupils have the opportunity to first meet their tutor at a New Pupils afternoon held in the Summer Term before they join the School. This is to offer support and reassurance at an early stage. In their second week at the School all Year 7 have a Life Skills Day where they work with their Tutor Group and tutor on a series of team-building exercises.

Pupils are very much encouraged to enter into the co-curricular life of the School by joining at least two of the many Clubs and activities which are available for them. A Freshers Fair is held early in the Autumn Term which helps give a flavour of the many activities on offer.

A dedicated Middle School Common Room is available for pupils in which to socialise and take part in various activities.

Middle School pupils study the most varied curriculum of any years in the Senior School. One of the unique subjects studied in Year 7 is the Portsmouth Curriculum. The pupils are taught seven strands throughout the year which explores a varied range of topics with a particular local emphasis.

A Middle School Ski trip to Italy is organised as a biennial activity. At the end of the Summer term a Middle School Adventure Weekend is arranged to Little Canada on the Isle of Wight.
