Dd1 is in yr4. There are two faith secondaries which we will consider - among other options. Both give priority to those attending church at least 3 times a month. We probably attend our local church 2/3 Sundays. No specific parish is prioritised, so would fall into the Catholic category for RC one and the 'any other Christian Church' category for the other school.
Outside of this we may well attend or visit churches - just not our parish one. For example both sets of parents are 80+ and live over 2 hours away, we visit them probably about 10- 15 weekends a year. When visiting FIL we will always take him to Mass. At my parents (less often) we will sometimes go to the cathedral, but it depends on our travelling plans and if we need to see FIL on the way back. We have tried to arrange to go to our church more since dd was doing her first Communion. On holiday we will usually visit churches/ pilgrimage sites (e.g. Lourdes) but not attend a French Mass. To complicate further now that ds is in nursery I will be free to attend my own church (c of e) midweek - our agreement on marriage was that the dc would be raised Catholic, and although I support dh in going with them to Mass I have increasingly realised that I will not convert so want my own church too.
How does the local priest decide who has attended regularly? There doesn't appear to be any sign in book, but they do take attendance at the children's catechism - term time only but they don't always want to go. Ds in fact is often vocal about not being there at all so we might be memorable! Do the other attendances count- do we need to document them to show to him/ school. I know we could just go to our local church more, but our elderly relatives are a higher priority than a school place - but don't want dd to miss out if she wants to go to them, like all other parents we just want the school we percieve to be best for her. It just seems that school admissions aren't geared up for the complexity of modern life.
