I'm considering a career change and am really interested in corporate learning and development but need a bit of advice. I've been a secondary school teacher for 20 years and, although I love certain aspects of the job (the actual teaching and lesson planning), I don't think I can do it for another 20 years before I retire. I have a little experience of managing/training adults as I'm a head of department but I appreciate that schools are very different to businesses. Would it be sensible for me to gain a more relevant qualification (and which one?) or should I try to get an entry level job to get more experience and then work my way up? Any advice would be greatly appreciated.
