Six students have got their first choice university spots after studying the international baccalaureate diploma.
Sir Henry Floyd Grammar School was the first Bucks school to offer the worldwide recognised qualification which is considered more difficult than A-levels.
The school’s six students scored an average of 33 points (4 points above the world average) and two got places at Oxford with higher totals than the university’s standard offers.
Headteacher Stephen Box said: “We have known for some time that the IB diploma is a top quality educational programme with an excellent reputation across the world – and particularly among university admissions tutors. These results have proved to us that we can teach it very well.
“We are finding that universities like the diploma so much that they are happy to accept students whose results are several points below the offer that the university has made.”
The two year diploma consists of maths, English, a language and three other subjects. Half the subjects are studied at a higher level and three at standard level. There is also an extended essay and 150 hours of creativity, action and service.
Mr Box said there are currently 17 students doing the IB and that a further 20 are expected in the next course.
