ST GUTHLAC School in Crowland saw a boost in its A*-C passes for students gaining five subjects including English and maths.
Executive headteacher Steve Baragwanath said: “It’s 44 per cent. I am very pleased. I think it’s gone up by about two per cent.”
Last year the school achieved a personal best with 78 per cent of students gaining five GCSEs at grades A*-C.
But this year that rate has dipped to 61 per cent.
Mr Baragwanath said the A*-C passes including English and maths were a credit to the school.
“The kids have made excellent progress and I wish them well in the next stage of their education,” he said. “I would like to thank all of the staff and the parents.”
Mr Baragwanath is also head of partner school George Farmer – and St Guthlac and George Farmer will be linked in an academy in the new term – and he said pupils’ achievements boded well for the success of the new academy.
He said: “We are absolutely thrilled with both sets of results.”
Among star performers at St Guthlac were Hannah Stevens, with six As and two Cs, Rebecca Candy with one A*, five As and two Bs, Rebecca Larter with one A*, four As, two Bs and two Cs, Coral Wild with two A*s, four As, one B and four Cs, and Sara Yusuf with two A*s and four As.
Twins Christina and Rachel Rogers (16), from Deeping St Nicholas, were both delighted with their results and planned to celebrate with a family meal and trip to the cinema.
Christina said: “I am so happy. I couldn’t sleep because I was so worried about my science results, but I did really well.
“I have done a lot better than I thought I would and got some As and A*s.”
She and her sister are both planning to go to Deepings School sixth form next year.
Rachel said: “I am really pleased – I worked really hard and I did really well.”
Vanessa Dorrian (16), from Cowbit, said she was disappointed by her results and could have done better, but was pleased she had done enough for a place on an engineering course at Peterborough Regional College.
Her friend Anouska Hemingway, of Spalding, got Fs, three passes and a G in her exams. She said: “I am really pleased as I thought my results would be worse.
“I’m going to have a party to celebrate.”
