The headmaster of The Misbourne said he is ‘over the moon’ after Ofsted found it has made more progress than any school in the UK.
Robert Preston arrived at the Great Missenden school a year after a damning 2010 report from government inspectors.
But Ofsted has now awarded the school a ‘good’ rating and said progress from unacceptable levels three years ago is the quickest it has seen.
Mr Preston has now turned around his sixth school in just eight years but has no plans to move on.
He said: “It’s a great place to work and there is something quite unique and exciting here.
“The students really engage with the fact that we have targets for every subject and they really want to chase these targets down.
“They are proud of their school, they look smart and they act smart. It gives them a real chance in life.”
Mr Preston, who said the school is only two years into a five year ‘game plan’, is aiming to achieve levels of outstanding in its next inspection.
He said: “We have a relentless focus on teaching and learning and these teachers are some of the best I have had the privilege of working with.
“I would send my children here, no doubt.”
The report said ‘achievement is good and rising rapidly’ with ‘some outstanding teaching’ which ‘prepares students well for future success’.
Mr Preston said: “We are very keen on developing students as people and student leadership is something I am very passionate about.
“We had 30 Year 12 students who do a ‘better reading partnership’ programme where they work with Year 7 students who are struggling.
“We have young enterprise, student councils and prefects.”
The secondary school, in Misbourne Drive, has more than 900 boys and girls aged 11-18.
