Crumlin Integrated College in Northern Ireland was put into formal intervention in early 2010.
The Education and Training Inspectorate (ETI) highlighted major deficiencies in leadership, poor teaching standards and exam results.
Principal Dr Annabelle Scott was subsequently removed from her post and sent for training. She later returned but was warned by police to stay away after a death threat was made against her.
In a follow-up visit, inspectors said the college was continuing to improve “by stabilising and developing its leadership capacity” and “strengthening the teachers’ capacity for effective teaching”.
In addition, inspectors noted the raising of standards, which the pupils attain, both in public examinations and in their wider skills and capabilities.
“In the areas inspected, the quality of education provided by Crumlin Integrated College is good. The ETI will continue to monitor, through district inspection activity, the school’s progress.”
Inspectors commented favourably on the present senior leadership in the school: “The stable leadership arrangements have enabled the process for self-evaluation to become embedded and to bring about further improvements across the school.”
Senior teacher Lynda McGarry said staff members are delighted at the outcome of the report.
“Throughout the process we always endeavoured to provide the children with the very best possible education,” she said.
“This report officially recognises the journey travelled and is testament to the professionalism and hard work of all the staff.”
Stanley Smith, chairman of the board of governors, added that the report confirms that the quality of the teaching is consistently very good.
“Great credit is due to our senior teacher in charge, Lynda McGarry, her senior management team and the entire school staff,” Mr Smith said.
“They have all gone through some difficult times and it is greatly to their credit that they have stuck to the basic task of ensuring that our pupils receive not only a really top class education but are also well prepared to play their part in society generally.”
