Just wanted people to note - for future reference that this link (which worked fine on my computer) says explicitly on page 4:
"Additional consideration is given to Welsh-domiciled and contextualised (see Cardiff University website for contextualisation information) applicants because they are under-represented in applications to UK medical schools."
I don't know when this was published, or how NoNotHimTheOtherOne got hold of it, and I hadn't seen it before it was put on this thread, but there it is in black and white. If you are Wales domiciled, you are treated as contextual by Cardiff. At least it makes that clearer.
It also really does seem to say that they rank by a) looking at academic qualifications, and setting a "threshold":
"Those who meet or exceed the minimum academic threshold will then be ranked and a cut-off point determined to proceed to consideration of the non-academic criteria (Personal Statement and Academic Reference) review (see Figure 1: Stage 2 of Selection Process)."
So it is academic but doesn't sound like it has to be 100% (up to them) to go to stage 2:
b) "Applicants who have reached or exceeded the academic cut off point for the year are considered on non-academic criteria according to the information in their Personal Statement and the Academic Referee’s statement. Applications are reviewed by trained selectors. See above for criteria reviewed.
The School of Medicine recognises that opportunities for certain types of work experience and participation in similar activities will vary according to individual applicant’s background, including socio-economic, cultural, and geographical circumstances. This will be considered when reviewing the Personal
Statement"
That is - it is now looking a lot like the old Bristol method of assessment - before they switched to just UCAT. ie you need certain minimum requirements, but the key now at Cardiff seems to be the Personal Statement, just when everybody else has stopped reading them.
