The Old Paludians Association, established in 1915, is the official alumni association for Upton Court Grammar and direct predecessor schools from 1912.

Membership of the Association is open to all former students and staff of Slough Secondary School, Slough High School for Girls, Slough Grammar School for Boys, Upton Grammar School, Slough Grammar School and Upton Court Grammar School.

As a result of the generosity of Old Paludians, the Association sponsors awards of equipment, books or funding towards special projects for the school.

Members of the Association bring a wide range of experience and expertise which is an invaluable resource for the school and both current and former students.
