Chris Hambleton, Assistant Headteacher at Rickmansworth School said: "We cannot thank all those who donated raffle and auction items enough, and a special thank to all those who made such generous bids.
"The generosity of our school community will make a big impact on our students education".
More than 180 people attended the event and attendees included parents, teachers, governors and ex-pupils.
