Carre's Grammar School is said to be delighted with the achievements and dedication of its Year 13 students at A level and vocational qualifications.
Take up of university places is said to have increased nationally this year, and is reflected at Carre's.
Headteacher Nick Law said: "We are particularly pleased with the significant increase in the number of higher grades achieved, continuing the upward trend for the school. This reflects the tremendous diligence of our students, their scholarship and tenacity which open up extraordinary opportunities for our students allowing them to make ambitious choices and to flourish in a future of their own making."
Mr Law said A levels remain the "gold standard" of what you can achieve in school and the exams have become more challenging and rigorous, yet results hadimproved upon the excellent standards of the previous years.
The same is true for the BTecs and CTecs that students have taken, with many achieving distinctions.
Mr Law added: "Whilst students have worked hard over their time at the school, staff also deserve much praise for the support, encouragement, quality of teaching and many extra hours they have put in with the students. The same is true for the parents who have supported their sons and daughters, as well as the school, over the years. This demonstrates the strength
of the collaboration between the staff of the Sleaford Joint Sixth Form, the success of developing teaching that supports students and encourages independent learning, a skill that is required in many walks of life, and the partnership with parents.
"Our students continue to take a vast number of challenging subjects and they achieve highly in these areas, allowing them to access courses at some of the country’s top universities, including Oxford and Cambridge.
"Sixth Form study is a young person’s passport to the next stage of their lives: we wish all of our Year 13 leavers well as they progress to university, college, apprenticeships or employment and we celebrate their success."
