Cal. Business and Professions Code § 5096.21

(a) (1) If the board determines, through a majority vote of the board at a regularly scheduled meeting, that allowing individuals from a particular state to practice in this state pursuant to a practice privilege as described in Section 5096, violates the board’s duty to protect the public, pursuant to Section 5000.1, the board shall require out-of-state individuals licensed from that state, as a condition to exercising a practice privilege in this state, to file the notification form and pay the applicable fees as required by Section 5096.22. (2) A state for which the board has made a determination pursuant to paragraph (1) to require individuals licensed from that state to file a notification form and pay the applicable fees may subsequently be redetermined by the board, by majority vote of the board at a regularly scheduled meeting, to allow individuals from that state to practice in this state pursuant to a practice privilege as described in Section 5096. (b) The board shall, at minimum, consider the following factors when making a determination or redetermination pursuant to subdivision (a): (1) Whether the state timely and adequately addresses enforcement referrals made by the board to the accountancy regulatory board of that state, or otherwise fails to respond to requests the board deems necessary to meet its obligations under this article. (2) Whether the state makes the disciplinary history of its licensees publicly available through the internet in a manner that allows the board to adequately link consumers to an internet website to obtain information. (3) Whether the state imposes discipline against licensees that is appropriate in light of the nature of the alleged misconduct. (4) Whether the state has in place and is operating pursuant to enforcement practices substantially equivalent to the current best practices guidelines adopted by the National Association of State Boards of Accountancy provided those guidelines have been determined by the board to meet or exceed the board’s own enforcement practices. (5) Whether the state has in place and implements comparable licensure requirements.
