Aston squeezed in at the very bottom of this year's Financial Times ratings, so it's better than some schools but doesn't provide the same return on investment as schools like Warwick, Manchester, Cranfield, etc.

Triple accreditation is a bit deceiving - each accreditation organization has its own geographical focus, and there's not a lot of overlap between all three. So Stanford, Harvard, Wharton, etc. are not triple-accredited, and they're some of the world's top business schools.

Back to Aston. Average post-graduation salary tends to be around $83k, so do the math for ROI. Grads tend to go into IT roles, consultancies, finance. But if your goal is to go to the US, you should really do an MBA in the States instead.
