A Level Results August 2025
The Principal, Amy Cavilla announces, Radnor House Hits Historic A-Level High!
"We are proud of our students' excellent A level results borne of hard work and their love of their chosen subjects. These will allow them to secure places at their universities of choice.
The A* and A grades are at a historic high: 24% of students attained AAA - A*A*A*A*
One in five grades were at A*
Just under 80% of all grades were A*-B. A*-A (46%) and A*-B (79%) grades are higher than in 2024, which were at 42% and 73% respectively.
Our value added score is 0.37 - which tells us that each A level grade is over one third higher than it might have been, based on GCSE grades starting points.
The school's A Level results have been improving steadily year on year. In 2025, every single A level grade is just under a whole grade higher than in 2019. For example, a student who got 3 grade Bs in 2019, would get up to three grade A's in 2025.
Congratulations to our students and thank you to our dedicated team of staff and our community of supportive parents."
