More than 2,000 schools are assessed by name, town, local authority, and postcode, with academic results at the heart of the evaluation.

Helen Davies, the editor of The Sunday Times Parent Power Guide, shed light on the education sector’s challenges and triumphs.

She said: “The educational landscape is testing – budget challenges, rising student mental health issues, special educational needs, and an increasingly uncertain future.

“But there is also so much to celebrate from the dedication of teachers who are finding ever more innovative and impactful ways to enrich their students and give them the very best start in life.”
