Built from the blueprint, not from guesswork.
NNCC publishes exactly how the CCHT exam is assembled. Everything here is organized around that document, which is why your score means something more specific than a percentage.
Find your baseline
Answer a short set spread across all four domains. Your readiness score is weighted by how much each domain is worth on the real exam, so it cannot be flattered by strength in a small domain.
Practice where it counts
Every item is tagged to one of the 72 activities NNCC publishes. When you are weak, the dashboard names the activity and its blueprint reference, so you can drill exactly that instead of re-reading the whole chapter.
Sit full mocks under time
150 questions in three hours with no feedback until you submit, sampled to match both published dimensions — the domain weights and the cognitive mix.
What the exam actually covers
| Domain | Weight | Questions | Activities |
|---|---|---|---|
| I. Clinical | 50% | 71–78 | 34 |
| II. Technical | 23% | 32–38 | 11 |
| III. Environment | 15% | 19–25 | 13 |
| IV. Role Responsibilities | 12% | 15–20 | 14 |
Weights follow the published exam blueprint. Confirm current figures with NNCC before your test date.
The part most practice tests get wrong
The blueprint has a second dimension almost nobody matches: how hard the questions are supposed to be. Two-thirds of the exam asks you to apply knowledge to a situation, not to recall a definition.
Remember specific facts, common terms, basic concepts and principles. Definitions live here.
Interpret, compare, contrast, explain, estimate and translate. Deeper understanding of a concept.
Apply learned facts to new situations and solve problems. An on-the-job scenario asking what is happening or what to do.
Why this matters
A bank made mostly of definition questions will feel productive and then fail you, because the exam is not asking you to define uremia — it is asking what you do when the patient in front of you is diaphoretic at 78/44. Our mock exams sample to hit the published mix on both dimensions.
