Professional mobility for psychologists has been a problem since states first passed psychology licensing laws because of relatively small but crucial variations in licensing requirements. Although the profession of psychology and the association of psychology regulatory bodies in the United States and Canada (i.e., the Association of State and Provincial Psychology Boards [ASPPB]) have recognized this problem for decades, little progress was made in resolving it. Recently, the ASPPB launched two different approaches to facilitating professional mobility: one to forge agreements between regulatory bodies to accept each other's. licensees, and another to certify or endorse individual psychologists who meet ASPPB standards for licensure and therefore can be recommended to licensing boards for relicensure. The specific requirements of each of these programs and their success in addressing the professional mobility problem are described.
