Taking and passing an examination is just one of the requirements you will need in order to be eligible for licensure. Recent changes to the program have made it possible for an applicant to sit for an examination prior to obtaining the mandatory level of experience. This change allows the applicant the opportunity to sit for their examination while simultaneously obtaining their experience. Please view the links below to obtain more detailed information about the examination process.
