CCHT Recertification

COVID-19 Recertification Grace Period

For healthcare professionals directly impacted by the COVID-19 crisis, NNCC is offering 6-month grace period to meet recertification requirements with no penalty. Receiving the grace period is as simple as downloading and submitting the signed Grace Period Acknowledgement form along with your recertification application once requirements are met. Please download and review the form today so that you may understand the terms of the grace period, and then submit a signed copy of the form along with your recertification application to apply the grace period to your recertfication.

PLEASE NOTE: This grace period will not extend your certification period, but will allow up to 6-months past your 2020 certification expiration date to meet recertification requirements, if needed, due to COVID-19.

Certified Clinical Hemodialysis Technician® (CCHT®)

Attention Experienced Dialysis Technicians. If you have worked a minimum of 5 years and 5000 hours as a dialysis technician, you may be eligible to apply for the advanced CCHT-A examination. Show your knowledge and expertise with the advanced CCHT-A credential.

Current CCHT Certificants, NNCCs FailSafe policy protects you. If you take, but do not pass the CCHT-A examination, NNCC will grant recertification of your CCHT credential automatically.


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 three years from the last day of the month in which the applicant passed the examination. Certification must be renewed every three 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 CCHT by continuing education must be postmarked by the last day of the month in which your certification expires to avoid a late fee; however, because it can take up to 8 weeks from the date applications are received to be reviewed, NNCC recommends submitting your application at least 3 months in advance of your certification expiration date. All recertification eligibility requirements must be met during the three year certification period.
