: If you don't mind me asking, how old are you ? What salary level are you looking at ?
You said you want to change careers, but do you know how the IT industry works ? i.e. the whole software/system lifecycle. If you understand this, then you will know what jobs are required for every stage of that cycle. This is what people meant by "what sort of IT".
The cycle goes roughly something like this:
Data requirements/capture (e.g. business analyst role) ->
Modelling (e.g. business anaylst role) ->
system requirements (e.g. system analysts) ->
development of system/software (e.g. developer, application developer) ->
testing (e.g. developer/tester) ->
support (e.g. 1st line helpdesk, 2nd line helpdesk, 3rd line helpdesk roles)
Then it can go back to data requirement again for refining the system a second time round.
I can say that, most people get their foot in the door by doing support work. I too did this as well. Then went onto development.
If you want to serious sustain and make a career in IT, then it's good to have a programming language behind you. Currently, it's Visual basics, possibly other web-based scripting language too...
Forget the courses like ECDL. It's more user-orientated, and it's practically no use to a technical person. We don't need you to know this, because the more technical you become, the less such qualification are to you. They are too "high-level". (Oh, also get used to such computer jargons will help too.)
By the way, what industry were you working in before ? Maybe you should approach it this way. Make good use of your previous knowledge, and find a company which will train you in such areas ? For example, if you were working in an engineering company before, and you have knowledge of the engineering industry. A job advert for a low-entry level CAD designer would be ideal for you.
In my last job, I worked with a p/t housewife who was a user/support person, and had absolutely no knowledge what-so-ever of the IT industry. She just clicked, clicked, clicked following a manual.
That's the way the industry goes...
I hope you know what you're getting into. If you want to remain on top of the game, sometimes you gotta self-learn as well, and keep up with certain technologies, and such. I feel I'm dumbed down a lot too in my previous jobs compared to my peers who worked in small companies, but learnt a hell of a lot more in terms of development and computing skills.
