About Parmiter's School

Parmiter's School is one of the most sought-after state secondaries in Hertfordshire, and the numbers tell you why. For the 2025/26 admissions round, the school received 1,451 applications for just 198 places, giving an oversubscription ratio of 7.33. Of those, 556 families put it as their first preference, and 176 first-preference offers were made. That level of demand is a strong signal from local parents, and it's backed up by the school's most recent Ofsted inspection in 2024, which awarded Outstanding across every single category: quality of education, behaviour and attitudes, personal development, leadership and management, and sixth-form provision. It's a clean sweep of top grades, and the school has held an Outstanding rating consistently since at least its previous inspection in 2011.

Academically, Parmiter's is performing well above the national average. Its Progress 8 score of 0.74 is classified as 'Well above average', meaning pupils here make nearly three-quarters of a grade more progress per subject than similar students nationally. That puts it first among the seven secondary schools in the Three Rivers local authority area, and 27th out of 350 schools in the East of England region. The Attainment 8 score sits at 68.3, and 94.3% of pupils achieved a grade 4 or above in English and maths. The school also has a strong EBacc focus, with 73% of pupils entering the EBacc suite of subjects and 62.1% achieving a grade 4 or above across all five components. At A-level, the average points per entry is 42.51, equivalent to a B+ grade, and the school's value-added score of 0.11 is rated 'Above average', with 38% of entries achieving AAB or higher.

The school is well equipped to support a wide range of students. Its facilities include a swimming pool, sports hall, science labs, music rooms, an ICT suite, and a dedicated sixth form centre. There are clubs covering everything from debate and Model UN to rowing, martial arts, and the Duke of Edinburgh's Award. Parmiter's also has a comprehensive SEND offer, with provisions for autistic spectrum disorder, dyslexia, speech and language needs, hearing and visual impairments, physical disabilities, and social, emotional and mental health support. With 1,464 pupils on roll against a capacity of 1,392, the school is slightly over capacity, and the 7.7% of pupils eligible for free school meals is below the national average. This is a high-performing, heavily oversubscribed school that suits families who value strong academic outcomes and a broad extracurricular offer, but securing a place is extremely competitive.
