Hi,
I live in Wantage and have three children, the eldest is about to start secondary school this year and the little ones are 2 and 1.
Wantage is a great place for schooling, the three Wantage primaries (Wantage CofE, Charlton and Stockham are all good as is Millbrook in Grove. Grove CofE has mixed reviews but on personal experience it's ok. Theyre pretty evenly matched so it comes down to personal preference and I'd recommend visiting them. If you haven't found a house yet, it's worth looking at Oxfordshires website as they have a page where you put the postcode in and it tells you the catchment you'd be in. In Grove you have a choice of either school.
My eldest went to Charlton, so that would be my personal recommendation, fantastic school with strong leadership and a caring nurturing environment. They have a preschool, Charlton Acorns which by all accounts seems to be good but you need to be in catchment and have name on waiting list pretty early it seems.
Grovelands preschool in grove is very nice and has a lovely purpose built building.
There is a children's centre in the town (next to museum and police station) they have a number of drop in sessions a week. There are also music, sensory and art groups. St johns church in grove runs groups on a Monday and Wednesday and Wantage baptist runs one on a thursday. The children's centre does a saturdads group I think monthly too.
I've lived here forever, and it's great, people are welcoming especially at the children's centre.
