Caistor Yarborough Academy head teacher Jeremy Newnham has praised students and staff for the results achieved this year.
In Science, 87 per cent of students gained an A*-C grade.
Overall, 55 per cent gained five or more A*- C grades, including English and Maths, with 100 per cent of students gaining one or more A*- G, with 65 per cent five or more A*- C.
“2015 has been yet another positive year for CYA,” said Mr Newnham.
“Every member of staff and all of our students have worked hard and successes are well deserved.
“This is the first year when all examinations have to be taken at the end of the two year course. Students have to retain so much information and many sit more than 20 examinations.
“Levels of progress, the measure that shows how well they have done since primary school, continue to improve in core subjects with English and Science being well above national averages.”
Three students - Georgina Marshall-Latimer, Jade Holness and Luca Grima - exceeded expectations in all areas and will attend a celebratory presentation at Westminster Central Hall, London in September.
Chair of Governors, Tony Maund said: “Again, well done to our students and our dedicated staff.
“I do not think that the community realises how much support is given to our students to achieve these results. Do come and visit us and see this work yourself.”
