Ark Charter Academy
Southsea, PO5 4HL · Portsmouth · secondary school
8th of 10 secondary schools in Portsmouth we can score. Local and same-phase on purpose: a national table mostly measures who attends.
Narrow the comparison to schools whose pupils have similar backgrounds and it does better still — 5.8/10 against 124 of them, against 2.6/10 nationally. Both figures are results only, without the inspection grade. A lower figure here means a stronger comparison group, not a weaker school.
How this is worked out
| Measure | Percentile | Weight | Adds |
|---|---|---|---|
| Grade 5+ English & maths 2024/25 | 35.9 · 30 | 46% | 1.38 |
| Progress 8 2023/24 | -0.32 · 26 | 38% | 0.99 |
| Attainment 8 2024/25 | 38.9 · 16 | 15% | 0.25 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.

Beyond the classroom. Pupils can join the Maths Cipher Challenge, 7Gs Research Project, Dungeons & Dragons Club, Music Tech Club, Biscuit Band, Debate Club, STEM Club, Axiom Maths, Netball Club, Football, Girls’ Football, Chamber Choir, Drama Society, Poetry Workshop, Choir, Art Club, and the Duke of Edinburgh Award.
Getting in. There are 917 pupils in a school with 900 places, meaning it is over capacity by 17. The school is over its stated capacity, so places are competitive.
Worth asking on a visit. How does the school manage the pressure of being over capacity for new admissions? What support is available for pupils who need to close the gap between their current attainment and the national median? How do you ensure the 7Gs Research Project remains accessible to all students, not just those with prior experience?
