The Certified Clinical Hemodialysis Technician examination is NNCC’s certification examination for hemodialysis technicians: 150 multiple-choice questions in 3 hours, of which about 25 are unscored pilot questions, delivered by computer through PSI. NNCC reports the result as pass or fail and does not publish a percentage passing standard. Its test blueprint divides the examination into four practice areas — Clinical at 48–52%, Technical at 21–25%, Environment at 13–17% and Role Responsibilities at 10–14% — each question also tagged to a cognitive level of knowledge, comprehension or application.
The CCHT is the national entry-level certification for the technicians who deliver hemodialysis treatment: preparing the patient and the machine, cannulating and monitoring vascular access, watching the treatment minute by minute, responding to intradialytic complications, managing water treatment and dialysate, and closing treatment safely. The Nephrology Nursing Certification Commission (NNCC) awards the credential, with applications handled through its testing partner C-NET and the computer-based examination delivered by PSI. PassProfessor’s CCHT program is in development as part of the expanding PassProfessor catalog, built to NNCC’s published CCHT test blueprint.

Which technician credential is this?
NNCC’s Certified Clinical Hemodialysis Technician — the CCHT. NNCC also offers an advanced credential for experienced technicians (the CCHT-A) with its own requirements and examination focus; this program is the CCHT, the entry-level certification, and its blueprint is the one quoted throughout this page. The CCHT is a certification of the technician’s knowledge and competence for the employing facility and the profession; it sits alongside — and does not replace — your facility’s training, competency requirements and any state rules that apply to dialysis personnel.
Who can take this examination?
The CCHT is NNCC’s entry-level technician certification, built for technicians working in hemodialysis: NNCC’s application materials require a high school diploma or equivalent and dialysis technician training and clinical experience under the terms NNCC publishes, and NNCC recommends substantial clinical experience — commonly expressed as six months or 1,000 hours — before testing, as guidance for readiness. Because NNCC’s current application booklet is the governing document and its terms are the ones your application is judged against, take the exact eligibility list from NNCC’s current CCHT application materials before you apply.
The outline, area by area
| Content area | Published weight |
|---|---|
| Clinical | 48–52% · about 72–78 questions |
| Technical | 21–25% · about 32–38 questions |
| Environment | 13–17% · about 19–25 questions |
| Role Responsibilities | 10–14% · about 15–21 questions |
What does Clinical cover? (48–52% · about 72–78 questions)
Half the examination, and the treatment itself: patient preparation and assessment before treatment, vascular access evaluation and cannulation, treatment initiation, intradialytic monitoring, recognition and response to complications, medication-related procedures within the technician’s role, laboratory sampling, emergency response, and treatment termination and post-dialysis care. Its questions follow the treatment chronologically, and they test the technician’s vigilance — what you check, what a change means, and what you do and escalate, in what order.
How should you prepare for Clinical? Allocate study time in proportion to its published weight — 48–52% · about 72–78 questions — and then adjust by evidence: survey the area early, note where your reasoning breaks down, and return with focused practice rather than rereading. The questions in this area reward applied judgment in realistic situations, so preparation should pair every block of reading with questions answered under time, followed by a careful review of why each wrong option was wrong. Keep a running list of the distinctions this area tests most finely; on this outline, small distinctions inside a heavily weighted area are worth more than broad familiarity everywhere.
What separates strong candidates in Clinical? Usually not more facts, but cleaner sequencing: recognizing the decisive feature of a situation first, discarding options that are true but not responsive, and choosing the action the situation calls for now rather than eventually. When you review practice in this area, classify every miss before you move on — knowledge gap, misread situation, or wrong priority — because each class has a different repair, and lumping them together hides the pattern your next study block should attack. Revisit the area in mixed practice before you test; competence that only appears when you know the topic in advance is not yet examination competence.
What does Technical cover? (21–25% · about 32–38 questions)
The machine and the circuit: hemodialysis machines and the extracorporeal circuit, dialysate composition and delivery, equipment checks and testing, alarms and troubleshooting, water-treatment systems and quality-control testing, concentrate preparation, and recognition and reporting of equipment-related adverse events. Technical questions reward technicians who understand why a check exists — conductivity, pH, temperature and pressure readings as safety evidence, not rituals.

What does Environment cover? (13–17% · about 19–25 questions)
The treatment environment as a safety system: infection prevention and control in the dialysis unit, water and dialysate quality as environmental conditions, safety practices and hazard recognition, and the quality-assurance habits that keep a unit’s environment inside standard. Much of this area is AAMI-anchored practice — the standards culture of the dialysis unit, tested as applied knowledge.

What does Role Responsibilities cover? (10–14% · about 15–21 questions)
The professional frame: communication with patients and the care team, patient education support within the technician’s role, documentation, and the responsibilities and boundaries of the technician’s scope — what the technician does independently, what is done under direction, and what is escalated to the nurse or provider. Small in weight, and the area that defines safe practice in all the others.

How is the examination scored?
NNCC reports the CCHT result as pass or fail, and NNCC does not publish a percentage or raw passing standard for candidates to aim at. This page therefore states no passing figure — any percentage attached to the CCHT by a secondary source is that source’s claim, not NNCC’s published standard, and it does not appear here. The honest preparation target is blueprint-wide strength: the passing line is applied across the whole examination. Where PassProfessor practice uses 70, 70 is a PRACTICE BENCHMARK ONLY — our study target, with no relationship to NNCC’s unpublished standard.
Two consequences follow for preparation. First, the standard applies to the examination as a whole, so there is no honest strategy of clearing it area by area: a neglected area taxes the same result your strongest area feeds, and margin across the whole outline is the only form safety takes. Second, any practice percentage — in any provider’s material, including ours when the program opens — is a study instrument, not a prediction and not a conversion toward the body’s standard. It tells you where your performance against that practice stands today, and where the next block of study belongs.
What does the real examination cost?
NNCC’s published examination fee for the CCHT is $225. That is NNCC’s fee for the examination itself, paid with the application through C-NET — separate from any preparation. Confirm the current figure in NNCC’s current application booklet when you apply, because fees change.
Keep the two kinds of price separate in your planning: the certifying body’s examination fee, above, is what the credential attempt costs; PassProfessor’s program, when enrollment opens, is a separate preparation purchase whose price will be announced with the launch — no program price is stated while the program is in development.
How should you study for this examination?
- Study in the treatment’s own order. The Clinical half of the blueprint runs pre-treatment, initiation, monitoring, complications, termination — learn it as one shift-long sequence and the monitoring logic connects itself.
- Make alarms a language. Technical questions turn on what each alarm protects against and what the technician checks first; pair every alarm with its cause list and its first response.
- Treat water as a clinical subject. Water treatment, dialysate and their quality testing span the Technical and Environment areas, and they are the least intuitive content for new technicians — start early, not last.
- Drill complication response until it is ordered. Hypotension, cramping, air embolism, blood leaks, access problems: the examination tests sequence — stop, protect, assess, escalate — under time pressure.
- Finish with full 3-hour timed practice mixing all four areas and all three cognitive levels, and test when no blueprint area is collapsing. In this program, 70 is a PRACTICE BENCHMARK ONLY, with no relationship to NNCC’s pass/fail standard.
How should you read this blueprint?
Weights are instructions, not decorations. A published weight tells you where the examination’s questions live, and therefore where your hours earn the most. Read the table in this guide the way the test-maker wrote it: the largest areas deserve the largest blocks, studied earliest and revisited most often, and no area inside the blueprint is optional. A candidate who studies every area equally has made a decision too — to over-invest where few questions live and under-invest where most of them do.
Ranges mean what they say. Where an outline publishes a range rather than a single figure, forms of the examination are assembled anywhere inside that range. Do not plan against the friendly end of a range. Plan so that your preparation holds at the demanding end: if an area can carry the top of its range on your form, your study should already have treated it that way.
The outline is also a boundary. It tells you what will not be tested as surely as what will. Content from neighboring credentials, deeper clinical or technical levels, or retired versions of this same outline may be interesting, and some of it may even be useful background — but it earns nothing here. When a source cannot be traced back to this outline’s areas, set it aside until the blueprint itself is secure. That discipline is what keeps a finite study season pointed at the examination you will actually sit.
What does a four-week study plan look like?
Week one — survey and foundations. Work through every content area once, at survey depth: Clinical, Technical, Environment, Role Responsibilities. The goal is an honest map, not mastery — finish the week knowing which areas are familiar, which are rusty and which are genuinely new, and set your remaining weeks from that map rather than from preference.
Week two — the heavy areas, deeply. Give the largest published weights the largest blocks. Study each heavy area in the order the outline presents it, pairing reading with timed questions the same day, and keep the error log started in week one: every miss classified as knowledge, reading or priority. By the end of week two the heavy areas should feel worked, not merely visited.
Week three — the remaining areas, plus repair. Cover the smaller areas completely — on a weighted outline, small areas are where prepared candidates separate, because everyone studies the large ones. In parallel, run repair blocks on week two’s error patterns. Mix areas within each study day from this week onward, so retrieval stops depending on knowing the topic in advance.
Week four — full timed practice and taper. Sit at least one full practice sitting at the real examination’s length and pace, review it question by question, and spend the remaining days on the two weakest areas and on logistics: identification, check-in, breaks and timing discipline. Arrive with the outline’s shape in your head and your own weak ground already repaired.
What happens on test day, and after?
Before the sitting. Confirm the delivery route and its rules from the certifying body’s current candidate materials — identification requirements, check-in timing, what may and may not be brought into the testing room, and how breaks work on this examination. These rules are administrative, but they are absolute on the day, and learning them the week before costs nothing while learning them at check-in can cost the sitting.
During the sitting. Work to the pace the recorded facts imply: divide the sitting’s length by its question count early, check yourself against that pace at the quarter marks, and do not let one hard question buy time from three later ones. Unscored questions, where the examination uses them, are not identified — the disciplined response to a question that feels foreign is the same as to any other: answer it as well as you can and move at pace.
After the sitting. Read the result and any score reporting the body provides as study documents. Where area-level reporting is given, it is the certifying body’s own account of your sitting and it outranks any reconstruction from memory — a retake plan, if one is needed, should be built from it area by area. Where the result is a pass, note the credential’s validity and renewal terms while they are in front of you, so maintenance never becomes a surprise.

Frequently asked questions
What is the CCHT? NNCC’s Certified Clinical Hemodialysis Technician credential — the national entry-level certification for hemodialysis technicians, earned by passing NNCC’s 150-question certification examination.
How many questions are on the CCHT examination, and how long is it? 150 multiple-choice questions in 3 hours, computer-based at PSI testing centers. About 25 of the questions are unscored pilot questions being evaluated for future forms; they are not identified.
What score do I need to pass? NNCC reports the result as pass or fail and does not publish a percentage passing standard. This page states none, deliberately — prepare for strength across the whole blueprint rather than for a borrowed number.
What are the four practice areas and their weights? Clinical 48–52%, Technical 21–25%, Environment 13–17% and Role Responsibilities 10–14%, per NNCC’s test blueprint. Every question also sits at a cognitive level: Knowledge, Comprehension or Application.
Who is eligible for the CCHT? Technicians working in hemodialysis who meet NNCC’s published application requirements — including a high school diploma or equivalent and dialysis training and experience under NNCC’s current terms. NNCC recommends substantial experience before testing. NNCC’s current application booklet governs; confirm the exact list there.
Is the CCHT the same as the CCHT-A? No. The CCHT-A is NNCC’s advanced credential for experienced technicians. This program is the CCHT, NNCC’s entry-level certification, built to the CCHT blueprint.
Does the CCHT replace my facility’s training? No. Certification sits alongside your employer’s training and competency program and any state rules for dialysis personnel; it does not replace them.
How do I apply? Applications are processed through C-NET, NNCC’s testing partner, and the examination is delivered by computer at PSI testing centers. Follow NNCC’s current application booklet for the steps and documentation.
Are these NNCC’s actual examination questions? No. When this program opens, its questions will be original practice questions written by PassProfessor to NNCC’s published blueprint. We never use actual examination items, recalled items, or another provider’s material.
When will enrollment open, and what will it cost? The program is in development as part of the expanding PassProfessor catalog, and no price is stated while it is in development. Join the notify list and the launch email will carry the price and the enrollment link.
What do the blueprint’s cognitive levels mean for studying? Knowledge questions test recall of facts and standards; Comprehension questions test whether you understand what a finding or reading means; Application questions hand you a treatment situation and test what you do. A study plan of pure memorization prepares only the first level — the blueprint’s design expects all three.
Why does the blueprint give ranges instead of exact percentages? Because examination forms are assembled within ranges — Clinical may be 48% on one form and 52% on another. Study to the range: no area can be treated as fixed, and no area inside its range can be safely ignored.
How is certification maintained? NNCC certification is maintained on NNCC’s recertification cycle, through the continuing-education and practice requirements in NNCC’s current recertification materials. Take the current cycle terms from NNCC as renewal approaches — this guide prints no recertification figure it has not verified.
