Mill Hill County High School

About Mill Hill County High School

Mill Hill County High School’s headline Progress 8 score of 0.24 is well below the Barnet local authority average of 0.6, placing it 25th out of 32 secondary schools in the borough. That gap is significant — the school is performing above the national average (which sits at zero), but it is not keeping pace with the high standards set by many of its neighbours. In a borough where six schools are rated Outstanding and the top three peers all post Progress 8 scores above 1.2, Mill Hill County’s score of 0.24 looks modest. The school’s ranking in the bottom quartile of Barnet schools (85.7th percentile) and in the 55th percentile across London suggests it is a solidly good school in a very competitive area, rather than a standout performer. Nationally, it sits around the 31st percentile, meaning roughly two-thirds of schools in England achieve a higher Progress 8 score.

Academically, the picture is mixed. At KS4, the school achieves an Attainment 8 score of 57.5 and a strong basics measure of 81.9% of pupils achieving a grade 5 or above in English and maths. The EBacc entry rate is high at 84.9%, and 56.7% of pupils achieve the EBacc at grade 5 or above — well above the national average. However, the Progress 8 breakdown shows that the strongest gains are in the EBacc subjects (0.43), while open subjects are flat (0.06) and English and maths are modest (0.18 and 0.27 respectively). At A-level, the school’s value added score is -0.03, classed as ‘Average’, with an average point score per entry of 35.01 (equivalent to a B- grade). The best three A-levels average out at a C+ grade. So while the school gets strong GCSE results, its sixth form adds less value than its KS4 performance might suggest.

The school is heavily oversubscribed: for 230 places in 2025/26, it received 1,032 applications — an oversubscription ratio of 4.49 to one, with 316 first-preference applications for just 187 first-preference offers. This suggests strong local demand, likely driven by its good GCSE outcomes and broad curriculum. Facilities include a theatre, sports hall, playing fields, science labs, music rooms, and a dedicated sixth form centre. The school offers a wide range of sports and clubs, from rowing and martial arts to Model UN and the Duke of Edinburgh’s Award. SEND provision is comprehensive, covering specific learning difficulties, autism, speech and language needs, and physical disabilities. This is a school that suits families who value strong GCSE results and a broad extracurricular offer, but who are realistic that it sits in the shadow of Barnet’s highest-performing grammars and outstanding schools.
