I wasn’t going to send my children to a catholic school either. There was a local outstanding school that was “the” school everyone wanted, and a good community school.
I hated the outstanding school, was meh about the community school. Visits felt very sales pitchy and look how wonderful we are.
thought oh fuck it I’ll go and see the catholic school just so I know I’ve ticked all the boxes.
what pp said about “old fashioned in a nice way” about nails it. They got two year 6’s to come down and show me round, the atmosphere was quiet and calm, except for the wonderfully batty music teacher collecting children from their classes for choir practice.
interestingly it was less “churchy” than the local community school. Yes they went to mass, most kids were involved in church at weekends, but for a non- denominational school the community school went to church weekly, the vicar was in a lot for assembly etc.
most catholic schools prioritise looked after children, then catholic siblings, then baptised catholics, then other religions, then anyone else by distance.
if you don’t go to the local church that isn’t usually an issue wrt entrance. But if you live in a different parish you may be too far away if the school is oversubscribed.
