You can get in trouble if you represent yourself as a CPA even if you have passed the exams but haven't completed the other licensing requirements.
No ethics exam here although we do have ethics CPE requirements.
Also, yes- you have to have a year of experience supervised by a licensed CPA. They are also very meticulous about what type of experience counts. For example, just being an accounting clerk and booking AP or AR is probably not considered acceptable. I know alot of friends that have not had experience count.
From the State board's site:
The experience must involve the use of accounting, attest, management advisory, financial advisory, tax, or consulting skills. It must be of sufficient complexity and diversity, and be supervised and verified by a licensed CPA. The experience may be from employment in public practice, private industry, non-profit, or government and must be at least one year of full-time or 2,000 hours part-time experience, or a combination of these.
