No I meant why so many questions about this topic today.
In any case, the information should be on your state board's website or on the form itself. It should tell you if you the signing CPA needs to be your supervisor or not.
Here it is on Oregon's Board of Public Accountancy website (https://www.oregon.gov/boa/pages/licensing.aspx):
EXPERIENCE REQUIREMENTS FOR CPA LICENSE:
Applicants for the CPA license must obtain the experience competencies as described below and have a minimum of 12 months full-time employment or a total of 2,000 hours of equivalent part-time experience.
All experience must be directly supervised by a qualified supervisor licensee. A supervisor licensee is a person who holds an active CPA license issued by any state or a PA license issued under ORS 673.100 during the period of supervision and for at least five of the past seven years immediately prior to such supervision. NOTE: A Public Accountant (PA) may not act as a supervising licensee or verify an applicant's experience relating to attest services.
The supervisor licensee must directly supervise the applicant by having regular and meaningful interaction with the applicant in terms of planning, coordinating, guiding, inspecting, controlling and evaluating activities, and have authority over the employee being supervised. A licensee acting as a consultant or independent contractor to the applicant's employer will not meet the requirement of direct supervision.
