MCS Junior School opened in 1994 in School House, previously occupied by boarders, beside the River Cherwell and opposite the main school site.

Where MCS had previously educated only choristers below the age of 11, this created an intimate Junior School of the highest quality for boys aged 7 to 11.

Boys are admitted primarily at age 7 into J1 (year 3). There is the possibility for boys to join MCS aged 8 into J2 (year 4), aged 9 into J3 (year 5) and sometimes aged 10 into J4 (year 6), dependent on the availability of places. Find out more about Admissions to the Junior School

The Junior School is an integral part of MCS. It has its own Head, Mr Tim Skipwith and dedicated team of specialist teachers, whilst being under the overall direction of the Master and having access to Senior School staff and facilities. 

The Junior School runs a popular daily After School Care service for all pupils until 5.30pm. During these supervised sessions, boys have the opportunity to complete homework before indoor and outdoor activities commence.

The school prides itself on the quality of its pastoral, academic and extra-curricular provisions. All boys take the competitive entrance exam for the MCS Senior School and enjoy an outstanding record of success in this.
