"Once a doctor and with a training number (which follows you all the way to becoming a consultant) you are in the system. When you apply for jobs the university you went to isn't even named."
I'm afraid you lost me there Genevieva. Don't know of any "training number" that you mentioned. As far as I know, this is how it works:
When a (UK) candidate completes and passes their final year exams at medical school, their school registers their name with the General Medical Council (GMC). The GMC then conducts a thorough examination of the candidate to check and double-check that everything is in order and nothing goes amiss. Everything being well, the candidate is then given a 'GMC Number' (which is unique to the particular candidate and stays with them for life) and a 'Provisional Licence to Practise'.
It is a legal requirement that a doctor holds a licence to practise in the UK. Therefore, before a newly qualified doctor even starts their F1 training, they must already have been registered with the GMC with a (Provisional) Licence to Practise.
At the end of their F1 training after the first year and assuming the candidate satisfies all the conditions and requirements of the training, their 'Provisional Licence to Practise' then becomes a (Full) 'Licence to Practise'. The candidate then proceeds to do their F2 training for another year with a full GMC licence and many other restrictions lifted.
The GMC has a wonderful website that anyone can access and find out about any doctor or specialist. It tells you about a medic's year of registration - provisional or full - whether they are a GP or specialist; and yes, Genevieva their medical school where they graduated! I used to have lots of fun just being nosey trying to find out all the doctors that I came across; where they went to school, what year they qualified, etc.
Try it out yourself and see where your GPcame from.
