The name of the school is legible on the screenshot.
Btw, someone should have a word with its admissions officer about the failure to comply with the Admissions Code, as the 2024 entry admissions policy and SIF should have been on its website for te past 4 months.
But essentially (after 1: EHCP / LAC / PLAC and 2: Children of staff), criterion 3 in the 2023 policy awarda points for church attendance of parent / Sunday school attendance of child at any church in the Churches Together in England group, various other groupings both national and local, or a few other local churches which presumably aren't in any group, as @catndogslife has noted.
So as long as the church attended is somewhere on one of those lists, or one of the specifically named ones, then the applicant will be ranked under criterion 3, according to the points accrued.
(The Catholic Bishops’ Conference of England and Wales is a member of Churches Together in England).
Points are also given for attending a CoE primary and for having at least one sibling at the school. Tie break for equal points is home - school distance.
Criterion 4 is 'other applicants' (those not filling in a SIF), ranked on distance, but the document goes on to give the allocation of places for the previous year, and no places were allocated under this criterion.
