I'm returning to the UK early next year. I will continue working from home for my currently employer, but I'm also thinking about contingency plans should this not work out for me. Before I started my current job I ran a computer training business with DH, doing mostly MS Office and other software training. I'd like to do the Microsoft Office Specialist (MOS) exams before I leave for the UK, but now I've started wondering whether it would be better to wait until I'm back in the UK and then do ECDL? I get the idea that MOS is far more advanced than ECDL, but I'm not sure which one is most likely to be recognised by employers. I'd appreciate some advice!
