An impressive 97 per cent of students at Kesteven and Sleaford High School achieved at least five A*-C grades at GCSE including the core English and Maths subjects.
And 54 per cent of all grades achieved by Year 11 were a at the very highest A* and A grades.
Students also scored highly in the EBacc; a national measure of student success in English, maths, science, modern foreign languages and humanities GCSE courses - with 79 per cent achieving at least 5 A*-C grades.
An impressive 20 students achieved at least nine GCSE results each at A* or A grade.
Chloe McGill and Harriet Kirsopp alone amassed 20 A*GCSE grades.
Headteacher Josephine Smith said: “I am absolutely delighted that students’ hard work paid off . These are excellent results and students across the year group can be extremely proud of themselves. Their hard work, supported by their teachers and mentors, means they are really well placed for their A level studies.
“Whilst it is fantastic to celebrate the highest achievers who have worked so hard to achieve that level of success it is the students who have had to persevere and redouble their efforts when things get tough who deserve equal celebrations. The route to examination success isn’t always a smooth one for many and every student who has met their potential should be so proud. All of the year group have the chance to choose whatever next step they choose in their learning. We wish them well.”
She added: “Our students this year are notable for having combined their studies with busy extra-curricular lives whether that’s been competing in events such as national sailing competitions or regular commitments to local voluntary work. I would like to thank all staff, and parents too, for their hard work and support in helping our students achieve such an outstanding set of results whilst at the same time becoming such rounded young people.”
