St. Anthony’s School is federated with Littlegreen School, Compton.
This is a 'hard' federation which means that the schools are managed by one governing body. The schools work collaboratively, sharing staff knowledge and expertise, staff development opportunities, facilities and resources.
St. Anthony’s and Littlegreen enjoy 'soft' federation partnerships with Chichester High School for Boys and Fordwater School. This arrangement is less formal than the 'hard' federation and involves all four schools working closely to share good practise.
