All experience must be verified by two signed letters of reference:
  • One from the applicant's immediate supervisor (the same person who signs the application)
  • The other from a professional (e.g. a peer or mentor in the field of nephrology)
  • Both letters must include the applicant's legal name and verify his/her length of employment, character and specific job duties.

Currently Unemployed: If you are currently unemployed but have the minimum experience as noted for the exams above, you will be required to have your immediate past supervisor sign your application and write a reference letter. All other stated requirements apply.
