A Nottingham academy backed by one of the UK's leading universities has been ordered to improve amid concerns about "unacceptably low" education standards.
The Schools Minister Lord Nash has sent a "pre-warning" letter to the governors of Nottingham University Samworth Academy (NUSA), saying the school must perform better or face further action.
The letter raises concerns that around 32% of pupils achieved at least five A*-C grades, including English and Maths, in their GCSEs last year - down from 35% the year before and below the Government's minimum threshold of 40%.
Nottingham University, which co-sponsors the academy based in Bilborough, says NUSA has been working in partnership with the Torch Academy Gateway Trust since October to improve standards following the summer's exam results.
Lord Nash has told the governors that if the academy doesn't improve, an official warning notice could follow.
If the Secretary of State Michael Gove still isn't satisfied with progress, he could appoint new directors to take over at the top.
