Click Start Test above to launch a full-length CHT practice test weighted exactly like the real BONENT exam, or drill a single domain — Patient Care, Infection Control, Water Treatment, Machine Technology, or Education & Professional Development. Every question includes a clear explanation so you learn the reasoning, not just the answer.

The CHT exam — the Certified Hemodialysis Technician credential — is administered by BONENT, the Board of Nephrology Examiners Nursing and Technology, and is one of the long-standing national credentials for dialysis patient care technicians.[1] These free CHT practice questions and test prep mirror the official BONENT content outline so you practice the way the real exam is built.[5] For complete prep, pair these with our free study guide, flashcards, and cheat sheet.

What Is on the CHT Exam?

The CHT exam covers five knowledge areas: Patient Care (45%), Infection Control (18%), Water Treatment (15%), Machine Technology (12%), and Education and Professional Development (10%).[2]

Patient Care is by far the largest section — covering fluid management, patient assessment, documentation, and treatment management. Our full practice test is weighted to match:

CHT weighting by knowledge area (BONENT)
Patient Care45% · ≈68 Qs
Infection Control18% · ≈27 Qs
Water Treatment15% · ≈23 Qs
Machine Technology12% · ≈18 Qs
Education and Professional Development10% · ≈15 Qs

Practice Questions by Domain

Use Start Test for a full weighted CHT simulation, or open the hub and pick a single area to drill your weak spot. After each full exam, your results show a per-domain breakdown so you know exactly where to focus — most candidates need the most reps on Patient Care, which alone accounts for nearly half the exam.

What Are the Requirements to Take the CHT?

To take the CHT exam, you qualify through one of two routes. The experience route requires at least 6 months of nephrology patient care experience and current, active employment in an ESRD (end-stage renal disease) facility.[1]

The education route lets you apply within 2 years of completing a BONENT-approved educational program even without the patient care experience.

Note that federal ESRD regulations require newly hired dialysis patient care technicians to become certified within 18 months of hire, and some states add their own requirements.

How Do You Register for the CHT Exam?

You register for the CHT by applying directly through BONENT — submit the completed application form and exam fee before the posted deadline.[3] Candidates choose between computer-based testing (CBT, $255) and the paper-and-pencil exam (PPE, $235).

PPE test dates and locations are posted on the BONENT website; CBT applicants receive a confirmation letter and then schedule their own appointment at an available testing center within their eligibility window.

What Is the Passing Score for the CHT?

The passing score for the CHT exam is a scaled score of 70 on a range of 1 to 100.[4] Your raw score (the number of questions answered correctly out of 150) is converted to a scaled score, which adjusts for slight differences in difficulty across exam forms.

Because the conversion depends on the exam form you take, a scaled 70 does not correspond to a fixed raw percentage.

How Hard Is the CHT? (Pass Rate)

BONENT does not publicly publish an official CHT pass rate. The exam is generally considered moderately difficult: candidates with hands-on dialysis experience who study the official content outline tend to pass, while those relying on memorization alone often struggle with the heavily weighted Patient Care section.[5] The content rewards practical understanding — fluid management, patient assessment, and treatment troubleshooting — over rote recall.

The takeaway: drill until you’re consistently scoring above target on full-length practice — especially Patient Care and clinical-judgment scenarios — before you book your exam date.

What to Expect on Exam Day

If you test by computer (CBT), arrive at your testing center at least 15 minutes early to check in — bring a valid, unexpired government-issued photo ID whose name matches your BONENT application.[3]You’ll store phones and personal items before entering; no notes are allowed.

A short tutorial precedes the exam, then you have 3 hours to answer 150 multiple-choice questions. If you sit the paper-and-pencil exam (PPE), you report to a scheduled group session at a posted location. BONENT processes your results and posts your official score after the testing window.

Having simulated the full timing with practice tests makes that clock feel routine.

How to Use This CHT Practice Test

  • Recreate exam conditions. Take the full test timed, with no notes.[3]
  • Diagnose, then drill. Use a full CHT simulation to find weak areas, then drill them.
  • Prioritize Patient Care. It’s nearly half the exam and the biggest score-mover.
  • Learn the why. Read every explanation — understanding beats memorizing.
  • Answer everything. There’s no guessing penalty, so never leave a question blank.

Why Get CHT Certified?

The CHT credential is a widely recognized national certification for dialysis patient care technicians, often required by employers and by federal ESRD rules within 18 months of hire.[1] These free CHT practice tests are the most efficient way to get there.

Conclusion

Passing the CHT comes down to knowing patient care, infection control, water treatment, and machine technology cold — and being able to reason through clinical scenarios. Use this free CHT practice test to find your weak areas, then reinforce them with our study guide, flashcards, and cheat sheet to drill them to mastery, and walk in confident on test day.
