South Wonston has a primary school and not much else, which is the honest headline. The village runs its own primary and sends its older children out to the next place along. There are no published inspection grades sitting in front of this page, so anyone promising you a rating for these schools is filling in a blank. What you get instead is geography, a small local primary and a well-trodden route to secondary elsewhere.
The anchor is South Wonston Primary School, which sits in the middle of the village on Downs Road. The church of St Margaret's is attached to it and gets used for school functions, so this is the kind of small, woven-into-the-village primary that a place this size tends to have. For the early years, that is the school the village is built around, and for most families here it is the obvious and only local answer.
Secondary is where the children leave the postcode. South Wonston does not have a secondary school of its own, and the usual destination is Henry Beaufort School over in Harestock. That is a short journey rather than a village walk, so secondary-age life here means a daily hop out to the edge of Winchester rather than a stroll to the end of the road. It works, but it is worth picturing the actual commute before you assume the school run ends at eleven.
A word on catchment, because it trips people up. Naming the local primary and the usual secondary is not the same as being handed a place at either. Admissions run on their own rules, distances and year-by-year pressure, and a house near a good school buys you proximity, not a guarantee. Two identical families on the same street can get different answers in the same March. If a specific school is the whole reason you are buying, check that school's current admissions position directly and do not take the map's word for it.
It is also worth being clear about what this page will not do. It names only the schools that are genuinely current options for the village, the local primary and the secondary the village actually feeds into. Schools change. They close, merge and rename, and a name you half-remember from a few years ago may no longer be a live choice. Where the facts do not support naming a school, this answer leaves it unnamed rather than sending you after one that has quietly disappeared. Treat any school not confirmed on this page as something to verify before you rely on it.
The blunt verdict is that South Wonston sits at the middle of the scale on schools, and it sits there partly by default. There is a real village primary at its heart and a clear onward path to secondary, which is more than plenty of small villages can say. What there is not is a stack of published grades to prove any of it is excellent or to warn you off, so schools here are a solid, unshowy average rather than a selling point you can bank on. If schooling is the deciding factor in your move, do the legwork on the individual schools yourself, because this village gives you the structure and leaves the scoring blank.
