The question, more or less: "With an eye to filling the gaps afterwards, where to go or how to conduct a mid-life skills assessment and identify areas of ignorance?"
I don't have a post secondary education, having left high school in grade 11. I'd like to rectify that now; I know there are holes in my learning. However having worked alongside with, directed, and trained a number of graduate students I know the skills I've gained in my 25 years of work experience are sizable and with merit. (Computer and technical fields, specializing in system administration and geographic information systems with a few small forays into programming.)
It wouldn't really be appropriate to start off at ground zero, 1st year computer science for example, but if I tried to launch in at a higher level I'd probably drown in some pothole or other of missing assumed knowledge. I'm wondering if there's a place or service a person could go to and find out what they don't know. Preferably online because I live thousands of kilometres from any major urban centre.
I don't have a particular end game in mind, other than some sort of computer degree or high level technical certification because that's where I have the most skills to trade on. I don't give a hoot about letters after my name, but others do, so lets get me some. A bit ago I didn't make the short list on a job I applied for, "high school drop out" being heard louder than the years of experience. Soon after the successful candidate asked me for advice on how to do the work. :-/
So, on topic? If not, where might it be on topic?
