A second sixth-former from the same school has been killed in a car crash in six weeks.
And a former sixth-form pupil from Lord Williams's School, Thame, died in a third accident last weekend.
John Fulkes, head of the sixth form, said: "This dreadful waste of young lives is so tragic. Everyone here is deeply upset."
The latest victim was Luke Thomas Davey, 18, of Back Street, Tetsworth, who was killed in a single vehicle incident in Thame Park Road on Sunday.
He joined Lord Williams's sixth form last year after taking his GCSEs at his former school, The Oratory at Woodcote.
His family are setting up the Luke Davey Memorial Fund at Lord Williams's to get a permanent memorial to him.
Mr Fulkes said: "We will work with the family to set up what they feel would be fitting."
He said: "Luke was a very popular lad who had made his mark in a short time and was a leading light in getting together the Lord Williams's Yearbook." "He was an enthusiastic snowboarder - and he was the first lad I've ever had to tick off for skateboarding in the sixth form corridor. He was that sort of lovable character.
"He played rugby regularly for the first XV."
Luke's funeral will be on Wednesday at 11am at St Joseph's Roman Catholic Church in Thame. His family have asked for donations to the memorial fund.
He lived with his father Martin in Tetsworth and his mother lived in Salisbury. He had a sister and three step-brothers and sisters.
Another sixth-former, Anthony Slatford, 18, of Thame was killed in a car crash on bends outside Long Crendon just before Christmas.
He was a passenger in the car in which the driver was killed and two local young people hurt.
He too was a talented sportsman at Lord Williams's and friends and family have set up a memorial fund in his memory also.
Richard Fraser Goldsmith, 26, from Reading, who died in an single vehicle accident at Christmas Common on Monday, was a former pupil at Lord Williams's.
