Students and staff at Furze Down School, in Winslow, are celebrating after the school received an Outstanding Ofsted report.
Following an inspection in March, the special school for pupils with special educational needs has been judged outstanding in all areas.
The school, which teaches children aged from four to 19, is currently in the midst of a major rebuild.
Lessons continue to take place in the old school building, while the architect-designed new building is being erected on site.
Headteacher Sue Collins said: “This is the third consecutive time we have achieved this recognition since my appointment as headteacher in 2006, and is a huge testament to the commitment, professionalism and absolute determination of all those involved with our school.
“We are unwavering in our vision of the school as a centre of excellence for special educational needs. We have remained relentless in raising the expectations and aspirations of pupils, parents and carers, and in supporting them to achieve. We have given our children and young people opportunities, responsibility and trust, building resilience and self-belief.
“I am extremely proud of the way in which our pupils demonstrated their achievements to the Ofsted inspectors, and how they spoke with confidence, enthusiasm and pride about their school.
“With the completion of the new school scheduled for late autumn of this year, I shall look forward to finally having a building which fully supports our vision and aspirations for learning.”
