I'm a BSA at my company. We use the IIBA which is the standard for business analysis. Check out www.theIIBA.org for more information. They have a body of knowledge which is the basis for their certification. The cert requires a lot of experience so you may not be able to sit for the exam yet. They also have chapters across the country. I am a member of the one in Richmond. Let me know if you have any specific questions.
