Onslow College

Onslow College is a co-educational secondary (year 9-15) school in Wellington, within the Wellington Region, operating in the state sector, with 1,180 students on roll, and an Equity Index of 398. The school has been open since 1956.

With 1,180 students on roll, Onslow College is a very large school — larger than about 96% of New Zealand schools.

The school's Equity Index is 398, which is well below the national average of 463. A lower Equity Index signals less socio-economic need in the school's community than the national norm. The gap of 65 points is substantial enough to matter when comparing schools.

The largest group is European at 61.8%, with a meaningful Asian community at 23.5% — a mixed but clearly led roll.

On the isolation index the school scores 0.27 (low isolation) — this measures how far students travel and how accessible the school is, not how good it is.
