A Leicestershire school has gone from "inadequate" to "good" in just 18 months.
Wreake Valley Academy, in Syston, was told in April 2013 that it had serious weaknesses. It was placed in the failing category by education watchdog, Ofsted, when inspectors found that not enough students were progressing well enough.
However, inspectors who visited earlier this month, have now said that the school is "good" and progress has improved thanks to good and outstanding teaching.
Principal Tony Pinnock said: "We're very pleased that leadership and management's shared passion for staff and the school's community has come across in the report.
"The school's turnaround is down to team work with staff coming together to make the necessary improvements because they all wanted the school to be as good as it was possible to be.
"Teaching has improved thanks to working with a partner school - Beauchamp College, in Oadby, to share good practice and because we introduced staff training on a weekly basis which allowed teachers to talk about what was working best and what changes needed to be made. Now the majority of teaching is either good or outstanding."
The report says that Mr Pinnock is well supported by senior leaders and has focused "relentlessly on improvement and raising expectations".
It said that students conducted themselves well and their spiritual, social, moral and cultural development was strong.
In addition, the report said that staff had high expectations of students.
The school's governors were also praised for being "passionate and rigorous" in ensuring the school improved.
Mr Pinnock added: "Our governors have been absolutely fantastic at holding the school to account. They have received new training and are regular visitors.
"We're very grateful for their support and for parental support too. We held on-going discussions with parents to see where they thought we could improve. There's been a real willingness to change and morale has remained high. We're on the journey to becoming outstanding."
This summer's provisional results for the school show that 58 per cent of students achieved five or more A* to C grades including English and maths at GCSE.
Sixth form pupil George Sutton, 17, said: "There's a nice community feel about Wreake Valley and the teachers are supportive. We want to say thank you to Mr Pinnock for all of his hard work here."
Fellow pupil Kaitlin McCallum, 13, said: "The teachers are always really helpful."
Emma Moloney, 14, added: "There's really good pastoral support so if you have a problem, you know you have someone to talk to about it."
To improve further the school was told to make sure that teachers planned activities for the most able students to ensure they reached the highest standards, and to ensure that homework was consistently planned.
