CNN-NP Recertification

Certified Nephrology Nurse - Nurse Practitioner™ (CNN-NP™)

Continuing competence is the ongoing ability of a nurse and those working under the nurse's direction to integrate and apply the knowledge, skills, judgment, and personal attributes required to practice safely and ethically.

To maintain competence and prevent professional obsolescence, the Board of Commissioners requires that each NNCC certificant participate in continuing education to refresh existing knowledge and skill and to acquire knowledge and proficiency pertaining to new advances as well as state of the art information over the full spectrum of nephrology.

The five-year time period established for recertification is based on both the scope of issues that face nephrology nurse practitioners and the Board’s belief that new practices, research, and information are introduced in the field with enough frequency that professional development activities should be conducted routinely so that certificants remain current with best practices and emerging knowledge.

Certificants enrolled in graduate nursing degree programs may apply only nephrology related coursework toward the contact hour requirement upon successful completion of the course. Five (5) contact hours will be assigned for one (1) semester credit. Three (3) contact hours will be assigned for one (1) quarter credit.


As a courtesy, the NNCC will send reminders approximately every 30 days starting 120 days prior to certification expiration. Ultimately it is the applicant's responsibility to obtain the necessary application form and submit it to the NNCC before the certification expiration date. The NNCC is not responsible for undelivered mail. A recertification application can be obtained here on the NNCC website or by calling 888.884.6622. Your completed application, appropriate forms, copies of supporting materials, and fee must be submitted at one time. The initial certification is effective for five years from the last day of the month in which the applicant passed the examination. Certification must be renewed every five years.

Continuing Education and Clinical Experience

If you elect the continuing education option, you must submit a recertification application with required documentation and the recertification fee. Applications for renewal of your CNN-NP by continuing education must be postmarked by the last day of the month in which your certification expires.
