Exam format and score standard

The CCHT exam has 150 questions and a 3-hour time limit. That gives an average of 72 seconds per question, but candidates should not spend exactly the same time on every item.

NNCC states that the passing standard is a standard score of 95. NNCC also says this is achieved by answering 74% of test questions correctly.

If a candidate is unsuccessful, the exam report includes the score and a percent-correct breakdown by Dialysis Practice Areas. That breakdown is useful for retest planning because it points to weak domains.

Other listed NNCC fees include a CBT 90-day extension, expedited review, returned check or cancelled payment, late fee, incomplete application fee, duplicate wallet card or certificate, and certification validation letter.

The practice exam is not required. It also does not guarantee that the official exam will feel the same or produce the same result.

Permit timing

CCHT examination applications are mailed to C-NET. Permit processing can take up to 4 weeks. FastTrack permit processing can be 1 to 3 business days if requested.

Build this timing into the study plan. A candidate who waits until the end of training to think about documents may lose study momentum while waiting for processing.
