Hello po. It took me more than a year to be fully registered with the college for my RPN. Actually, it depends and varies on each individual, depending on what other outstanding requirements you still have.
For future applicants, as of August 12, 2014, the launch of the National Nursing Assessment Service will change the way international applicants to the College begin the registration process. The NNAS (National Nursing Assessment Service) will begin assessing all international nursing applicants to the College on August 12, 2014. After that date, all applicants with international nursing education and no previous registration as a nurse in Canada will begin the application process through the NNAS website. Applicants currently being assessed by the College will not be affected.
A collaborative effort involving nursing regulatory bodies from across the country, NNAS will be the first point of entry for all international applicants looking to become nurses in Canada. It is designed to provide initial assessment of an applicant's eligibility for registration by collecting, authenticating and validating documents related to proof of identity, education, registration history, previous nursing practice, and proficiency in English or French.
