Good, with one inconvenience attached. Seaton has its own primary in the town and two village primaries nearby. Roughly eight in ten graded settings across the county come back good or better. The nearest secondary school is a short drive, and on foot it is most of a morning. Sound schooling, awkward geography.
Ofsted has published an overall effectiveness grade for 172 settings across Devon, the local authority Seaton belongs to, and 138 of them sit at good or outstanding. That is roughly eight in ten. Three carry an outstanding grade, 31 require improvement and three are rated inadequate. Another 135 settings hold no published grade at all, which covers those not yet inspected rather than those that failed, so they should not be read as a hidden pile of bad news. These are county-wide counts covering a large rural authority, so they describe the general quality of the pool rather than the specific school at the end of your road.
Which matters, because a school being close is not a school being yours. Devon runs the admissions process, places at popular schools go before the disappointed parents have finished the appeal form, and living within sight of a set of gates guarantees nothing at all. Anyone buying for a particular school should read that school's published admissions arrangements against the exact address, not the postcode, and do it before the offer goes in rather than after.
Seaton Primary School is the one carrying the town's name and the one most families in the town will use. The Department for Transport's modelling, which dates from 2019, puts a primary school around 8 minutes away by car, 12 by public transport and 17 on foot, which in practice means the school run here is a walk rather than a queue of idling engines. The two villages this page also covers keep their own small primaries, Beer Church of England Primary School and Branscombe Church of England Primary School, which is the sort of thing that survives in coastal Devon long after the bank and the bus service have given up.
Secondary is where the map stops being helpful. The same modelling puts the nearest secondary school 19 minutes away by car and 25 by public transport, and 87 minutes on foot, which is a figure nobody should treat as a genuine option in February. Seaton has no secondary of its own, so from year seven onwards the day is built around a bus timetable or a parent with a car and a tolerance for the morning run. Families who move here for the beach and the price tend to discover this at the point their eldest turns ten.
Schooling is one of the stronger cards this area holds. The grades are dependably good, the primaries are close enough to walk, and the only real cost is that secondary education happens somewhere else and somebody has to drive.
