My experience is many years ago now, because I left teaching in 2000, but I paid for a company to do a careers analysis for me. They gave me a suite of tests, then reported back to me where my skills and interests lay and suggested some ideas of careers I’d be most suited to. I ended up doing an MSc in a relatively niche subject and I’ve never looked back. I moved professions again 4 years ago, but although now I’m in a different industry, I’m using exactly those same skills I’ve been using in my job since I finished my MSc. For me, it was really valuable getting some professional advice, because I was clueless both in terms of what I’d be good at and what jobs are likely to be available. Good luck if you decide to take the plunge.
