An investigation has been launched at an Isle secondary school after it emerged pupils have been taught the wrong GCSE lessons.
A blunder at South Axholme Academy in Epworth has meant more than 30 teenagers in year 11 have not received correct tutorials on their engineering course.
The admission has sparked fury from parents and pupils, who fear their exam results will suffer as a result of the blunder.
Children have now been asked to attend additional classes in their own time.
One pupil, who is hoping for a career in engineering and asked not to be named, told the Bells: “I am worried that I have been wasting my lunchtimes attending extra lessons to learn irrelevant information, I feel like I have wasted my time.
“This will affect me for the rest of my life.”
His father added: “It’s an absolute scandal. It will potentially have an impact on the grades they get. I’m absolutely furious.”
Parents claimed the wrong specifications may have been taught from as far back as September 2011, but this was not confirmed by the school.
Headteacher Marie Lister and chair of governors Paul Barratt issued a letter to parents informing them of the mix up.
Mrs Lister said in the letter that the mix up came to light in late January.
She added: “Immediate actions were put in place to provide interventions and support for all students. The reasons behind the insufficiency of the course work are being tackled.”
Additional ‘booster sessions’ have been arranged.
The academy has contacted the AQA exam board asking for ‘special consideration’ but Mrs Lister added it was ‘likely to pay it very little regard.’
Ofsted rated the school as good in January and made no mention of the issue. It said the curriculum was ‘well matched’ to students’ needs.
Mr Barratt said: “We had a recent Ofsted inspection and they are happy with the measures been taken. Senior management are looking into what has happened.
“The booster sessions have been successful and show that students are still on track to get the grades anticipated.”
