 1.10 Arbitis do not make false, deceptive, misleading, exaggerated or fraudulent claims about their work or qualifications. The certification is yours. You should operate within that certification and don't claim to know anything that you don't know because of your certification. Pretty simple as that. BCPAs have to do this too. Just because we're board certified does not mean we have the answer to everything the client will run to ever. We all have our training and our roles and responsibilities and we only claim to do those particular tasks we've been tasked with. Well, simple as that.
