Atlantic Academy Portland
Portland, DT5 2NA · Dorset · all-through school
17th of 19 secondary schools in Dorset we can score, 29 in total — the rest without enough published data. Local and same-phase on purpose: a national table mostly measures who attends.
Its results hold up when the comparison narrows to schools whose pupils have similar backgrounds — 0.4/10 against 674 of them, against 0.5/10 nationally. So this is not simply a reflection of who attends. 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 |
|---|---|---|---|
| Ofsted | 52 | 35% | 1.81 |
| Grade 5+ English & maths 2024/25 | 19.2 · 3 | 30% | 0.10 |
| Progress 8 2023/24 | -0.74 · 7 | 25% | 0.18 |
| Attainment 8 2024/25 | 34.0 · 4 | 10% | 0.04 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.
Get to know the school
How it's doing. The school is rated Good by Ofsted following an inspection in March 2026. In 2024/25, 19.2% of pupils achieved Grade 5 or above in English and maths. Attainment 8 was 34.0, compared to the national median of 44.6. Progress 8 was -0.74 in 2023/24, indicating pupils did worse than nationally matched peers. Its results are much the same when the comparison narrows to schools whose pupils have similar backgrounds, so the gap is not explained by intake (0.4 out of 10 against similar schools, 0.5 out of 10 against all schools).
Getting in. There are 748 pupils in a school with 1020 places, leaving 272 spare places. The school has real spare room, so a place is likely and classes are smaller than it is built for.
Worth asking on a visit. How does the school support pupils to close the gap between their current attainment and the national median? What specific support is available for students who are falling behind in English and maths? How does the school utilise its significant spare capacity to enhance the learning environment?
