Our local Catholic primary prioritises admissions for baptised Catholics who have a Certificate of Catholic Practice signed declaration by the parish priest, but the policy doesn't say how often we would need to go to church in order to get one, or for how long before we apply. I'm guessing that's the decision of the priest, based on his interpretation of Canon Law about mass attendance, and his benevolence towards transgressions. Does anyone have any experience of this type of policy? How long the practice has to be maintained generally speaking if there's no information about it in the policy?
