Your first post mentioned coaching, rather than counselling? If it is counselling you want to do, then that is better as there is more of an evidence-base around counselling than coaching.
I have read the link - is it this bit you are referring to?
*A government spokesman said £300m had been allocated to provide additional resources for early mental health intervention for all schools - primary and secondary.
"We are also helping schools to intervene early by offering mental health first aid training for a member of staff in every primary and secondary school."*
I work in the education sector and the first sentence is more likely to mean that they are giving £30m overall to organisations - probably including Place2Be - who already do work in this field and who can develop projects and resources for schools to use. It doesn't mean that they are giving £30m divided out to every school in the country to spend as they choose - as that wouldn't be an effective way of spending the money. However, if you wanted to train with Place2Be or another provider then now would probably be a good time, as they are likely to be getting an injection of cash! But, one of the criteria for doing that kind of training is likely to be that you are already working in a school and can therefore use what you learn directly with pupils.
The second part is likely to mean that one person already working in each school will get Mental Health First Aid training, but that would probably be an add-on to their existing duties rather than something they would do as the main part of their role.
The other route is to become a qualified counsellor or possibly a clinical psychologist to work with CAMHS - but the training is quite long.
I realise that is not totally what you wanted to hear, but hope that helps clarify the situation.
