The philosophy of the Physical Education Department is to develop pupils who strive for sporting excellence, whilst developing a genuine interest and enjoyment of physical exercise and sport, be it in a recreational or competitive manner. This aim is reflected not only in team games for which the major games are Rugby, Association Football, Netball and Cricket, but also by the opportunities to partake in sports such as: Athletics, Badminton, Basketball, Swimming, Table Tennis, Tennis, Cross Country, Golf, Hockey, Sailing, and Volleyball. 

The School runs an extensive sports programme that includes weekly Saturday morning sports fixtures against other schools in the local area, squad training sessions held during games afternoons and after School during the week.

The School and PE Department prides themselves on the high participation rate of Ewell Castle School pupils within sport and place high value on the experiences that playing sport can provide. These experiences fit perfectly into the School's values of personal integrity, mutual respect, social responsibility and lifelong resilience.

At Key Stage 3 (Years 7 to 9) teaching groups are split via Form Group – leading to small group sizes and individual coaching, with games afternoons taking place with a Year Group at a time. Pupils participate in Badminton, Hockey, health-related exercise, Basketball, Athletics and Golf during PE as well as Rugby, Football, Cricket and Netball in Games.

At Key Stage 4  (Years 10 and 11) pupils participate in Games afternoon activities (Rugby, Football, Netball and Cricket) once a week and also have the opportunity to represent the School in Saturday fixtures as well as mid-week Senior (U18) matches. Year 11 - 13 pupils represent the School in mid-week fixtures as well as having the opportunity to participate in activities such as fitness, golf, tennis, hockey and others.

The Department runs both GCSE and A-level courses and these have become increasingly popular in the last few years. Typically, a GCSE PE class has 15 pupils and a A-level class around 10. In today's job market the ability to work as part of team has never been more important and pupils who choose to study GCSE and A-level PE courses will get to show these skills on a regular basis.
