One of the requirements of professional associations for licensure is an evaluation of international credentials. This evaluation may be referred to as an "accreditation." The process, cost, lengths of time, and required documentation to complete an accreditation varies. Some professional associations have internal evaluation services, and others outsource their evaluation requirements to external evaluation services. If you want to get a license in a regulated profession, contact the professional association directly and ask about their evaluation requirements. You will want to contact the professional association before you get an external evaluation. This will help ensure you do exactly what is required by the association to join.
