What the NHA CPT test plan actually requires you to be able to do

Tasks and knowledge, not topics

The CPT test plan has two columns for every domain. Task statements are numbered by domain and letter — 3J is "Follow order of draw when performing venipuncture" — and they describe duties you must be able to perform. Knowledge statements are numbered k1 through k94 across the whole plan and describe what you need to know in support of those tasks.

NHA says items "might require recall and critical thinking pertaining to a knowledge statement, a task statement, or both". In practice that means an item can ask you what the order of draw is (knowledge) or what to do when you realise you drew out of order (task), and studying only one of those leaves you exposed.

Core Knowledge statements sit outside the domains and are "potentially applicable to any of the assessment domains".

What this means for the highest-weighted content

Order of draw appears four separate times in the plan, which is unusual:

• 3J — follow order of draw when performing venipuncture
• 3P — follow order of draw when performing capillary collection
• k59 — order of draw, angle of tube insertion, fill level and ratios, and number of tube inversions
• k72 — order of draw for capillary collection
• k78 — order of draw for blood culture collections

Venipuncture, capillary and blood culture orders are listed separately because they are separate sequences. That is exactly why the order-of-draw trainer on this site drills them as separate variants rather than as one list.

CLSI, named by NHA

Task 2O requires you to determine the venipuncture site "based on established Clinical and Laboratory Standards Institute standards", and knowledge statement k25 names CLSI among the operational standards you must know, alongside The Joint Commission and the College of American Pathologists.

This matters for how this site is sourced. NHA points at CLSI; CLSI publishes the order of draw; so the sequence taught here comes from CLSI's own published statement rather than from a prep vendor's wall chart.

Eligibility

Eligibility to sit the CPT is set by NHA and depends on your training programme and work experience. This site does not restate the current eligibility rules, because they change and NHA publishes them authoritatively. Check them on NHA's CPT page before you apply.

If you are weighing the NHA CPT against the ASCP PBT, the eligibility routes are the main difference and they are on the comparison page.
