Good, and good enough that the schools count as a reason to move here. About four in five graded schools across the county are rated good or better. The town's own primary is under twenty minutes' walk from the average home. One school is based in the cloisters of the abbey William built. The real contest here is getting a place at the school you want, not finding a decent one.
Ofsted has graded 67 settings across East Sussex, and 54 of them are good or better, which works out at roughly four in every five. Seven are rated outstanding, 7 requires improvement and 6 inadequate. These counts cover the whole county authority, not Battle alone, so they describe the system your child enters rather than the building at the end of your road. Another 84 settings don't have a published grade yet. That tells you nothing about their quality in either direction, and it's no reason to cross one off a shortlist.
The town's own primary is Battle and Langton Church of England Primary School. Around it, the villages have their own church primaries, including Sedlescombe Church of England Primary School and Catsfield Church of England Primary School, so a family in the outlying parts of the parish doesn't automatically end up in the town. At secondary level, Claverham Community College and Robertsbridge Community College are the two state options nearby. Then there's Battle Abbey School, which has occupied the remaining cloisters of the abbey since shortly after the First World War. It's hard to find a more on-brand place to learn about 1066.
Distances are manageable if you have a car, and less so if you don't. The Department for Transport's 2019 modelling puts the nearest primary about 19 minutes' walk from the average home, 9 minutes by car and 16 minutes by public transport. The nearest secondary is about 32 minutes on foot, 11 by car and 18 by public transport. The public transport times are the ones most likely to have got worse since 2019, as bus routes get cut. Families with a teenager and no second car should test the morning run before they buy, not after.
Living near a school is not the same as getting a place there. Admissions follow the council's rules, and a nearby postcode is not a guarantee. Buyers who assume the school at the end of the road comes with the house can be disappointed in the spring when the offer letters go out. Check the current admission arrangements for the exact address, not the town.
Schools are one of Battle's real strengths. The county's grades are strong, the local primaries are close, and the only real risk is assuming a place comes with the postcode.
