So I've got a higher degree and some profesional body membership (note, not charted status or similar) that entitle me to use postnominal letters.
Would it be expected to see these accompanying my name at the top of the CV, or does it mark you as rather full of yourself? The roles I would be applying for these qualifications/memberships would be at least somewhat relevant.
If your professional body membership is relevant to your current job search (i.e. you could imagine recruiters being told "a good candidate will likely have XXX qualification"), then I would put it at the top of your CV.
From what I can tell, recruiters pay a lot of attention to certain buzzwords and in-vogue qualifications. Putting something at the top of your CV draws attention and immediately allows them to tick that box.
If your educational level is unusually high (e.g. PhD level), then I would consider including it too. But from a personal perspective, I feel it slips a little towards self-aggrandisement. This may be a cultural thing - I'm British and we are sometimes overly reserved.
