It's a job I've done for 20 years (and done well) but I've never got accreditation or certificates (usually been working at small companies who've not had the cash to invest in them, neither have I).
I'm trying to give my CV a refresh and maybe look at career development courses.
Should I invest in these courses or can my record speak for itself, if I present it the right way? Perhaps if I present as more senior/strategy role-seeking, as opposed to administration of projects?
