would a graduate certificate in Accounting due? or do i need a masters in accounting?
To answer your question, either could would probably give you what you need… which boils down to a foot in the door, so that you can work at a company that needs to comply with SOX requirements. The best place to learn about this sort of stuff is in the real world, not in a classroom.

If you focus on this too much, there’s a risk that you’ll become redundant when the regulations change again, which seems to happen every few years. And along these same lines, the latest talk I’ve heard is that people are pushing for relaxation of SOX requirements anyway, as they’re impacting US firms’ ability to compete with European and Asian companies… might be just talk, but you never know…
