I went with specialisms - and am relieved by your comments that it is unlikely anyone will notice
Hevian the problem is I have never "specialised" in those areas. I qualified in some particular areas but never practised in them. I now want a job in one of the areas in which I have qualified but have no practical experience. It would be misleading (I think) therefore to suggest I have specialised.
But regardless I can assure you the words aren't made up
