- CHT recertification requires accumulating continuing education credits within a defined renewal cycle-plan early to avoid last-minute scrambling.
- Your CE choices should map directly to the five CHT exam domains, especially Patient Care (45%) and Infection Control (18%).
- BONENT oversees CHT recertification; credits must come from approved sources to count toward renewal.
- Keeping organized records of every CE activity-certificates, sign-in sheets, transcripts-is your best defense during an audit.
What CHT Recertification Actually Means
Earning your Certified Hemodialysis Technologist/Technician (CHT) credential from BONENT is a significant professional milestone. But the credential is not a one-and-done achievement. BONENT operates on a recertification cycle, meaning every CHT must demonstrate ongoing professional development to keep the credential active. Continuing education is the primary mechanism for doing that.
Recertification is not simply about renewing a card. It reflects the reality that hemodialysis practice evolves constantly-machine technology improves, infection control protocols are updated, water treatment standards shift, and patient care research advances. The CHT credential is meant to represent current competence, not a snapshot of knowledge from years past.
For candidates who recently passed the CHT exam, it is worth revisiting how the exam is structured, because that same domain blueprint guides what BONENT considers educationally relevant for recertification. If you want a refresher on how your performance was scored, the CHT Exam Score Report: How Results Are Calculated 2026 article explains the scoring mechanics in detail.
Breaking Down the CE Requirements
BONENT requires CHTs to complete a specific number of continuing education hours during each recertification period. The general structure follows a multi-year renewal cycle. Technologists must accumulate CE credits from BONENT-approved educational activities and submit documentation along with a renewal fee by the credential expiration date.
The key components of the renewal process are:
- CE hours: A minimum number of clock hours from approved educational programming must be completed before the renewal deadline.
- Renewal application: A formal renewal application must be submitted to BONENT with supporting documentation.
- Renewal fee: A fee accompanies the application; this is separate from any costs incurred while obtaining the CE credits themselves.
- Attestation: Applicants certify that all reported CE activities were completed as described. Falsification is grounds for revocation.
BONENT also offers a recertification-by-examination pathway for CHTs who prefer to re-sit the full exam rather than accumulate CE credits. Most working technologists find the CE pathway more practical, but the exam option exists and may make sense for those who have allowed a credential to lapse.
Aligning Your CE to the Five CHT Domains
The CHT credential is built around five clearly defined content domains. BONENT uses these domains to structure the exam, and they serve equally well as a framework for choosing relevant CE activities after certification. Selecting CE that maps to these domains does two things simultaneously: it satisfies renewal requirements and keeps your clinical skills current in the exact areas that define CHT competency.
Domain 1: Patient Care (45%)
The largest domain by exam weight, Patient Care governs the majority of a CHT's daily responsibilities. CE in this area might include:
- Vascular access monitoring and cannulation technique updates
- Intradialytic complication recognition and response protocols
- Hemodynamic monitoring during treatment
- Patient assessment and documentation requirements
- Nutrition-related considerations for ESRD patients
Domain 2: Machine Technology (12%)
This domain covers hemodialysis equipment-how machines function, how to troubleshoot alarms, and how to perform setup and disinfection correctly. CE opportunities here include manufacturer-led in-services, biomedical equipment workshops, and dialysis machine certification modules offered through professional associations.
- Alarm interpretation and troubleshooting workflows
- Circuit priming and blood flow mechanics
- Dialysate conductivity and temperature settings
Domain 3: Water Treatment (15%)
Water quality in hemodialysis is a patient safety issue, not a technical footnote. CE in water treatment is often underemphasized by technologists focused on patient-facing tasks, yet this domain carries significant weight both on the exam and in daily practice.
- AAMI/ANSI standards for dialysis water quality
- Reverse osmosis system operation and maintenance
- Water sampling protocols and microbial testing interpretation
- Carbon tank testing and chemical contaminant limits
Domain 4: Infection Control (18%)
The second-largest domain by exam weight, Infection Control is an active regulatory focus. The CDC, CMS, and state health departments all scrutinize dialysis facility infection rates. CE in this domain is plentiful and highly relevant.
- Bloodborne pathogen exposure protocols
- Hepatitis B and C surveillance in dialysis populations
- Surface disinfection sequencing and contact time requirements
- Vascular access infection prevention bundles
- Personal protective equipment selection and donning/doffing
Domain 5: Education and Professional Development (10%)
This domain covers the CHT's role in educating patients, caregivers, and colleagues, as well as the technologist's own professional growth. CE here might include patient education methodology courses, mentoring skills workshops, or professional association conference attendance.
- Health literacy and patient communication strategies
- Home dialysis training support competencies
- Preceptor skills for onboarding new technicians
A balanced CE portfolio will touch each domain, but given that Patient Care and Infection Control together represent 63% of the CHT exam blueprint, it is reasonable to weight your CE hours toward those areas. The CHT Exam Prep practice test platform organizes questions by domain, which can also help you identify knowledge gaps worth addressing through targeted CE activities.
Where to Earn Approved CE Credits
Not every educational activity qualifies for BONENT recertification. The source and format of CE must meet BONENT's standards. Broadly, the following categories are recognized:
| CE Source | Typical Format | Domain Relevance |
|---|---|---|
| NNCO / BONENT-approved programs | Online modules, in-person workshops | All five domains |
| National Kidney Foundation (NKF) conferences | Live sessions, symposia | Patient Care, Infection Control |
| ANNA (American Nephrology Nurses Association) | Webinars, journal-based CE, conferences | Patient Care, Infection Control, Education |
| Dialysis facility in-services (documented) | Staff meetings, competency training | Machine Technology, Water Treatment, Infection Control |
| College or university courses (relevant) | Semester-length courses | Varies by course content |
| AAMI educational resources | Standards training, webinars | Water Treatment, Machine Technology |
Always confirm that a specific program carries BONENT approval before investing time and money in it. Approval status can change, and CE completed through a non-approved source will not count regardless of educational quality.
Documenting and Submitting Your CE Hours
Documentation habits formed early in your recertification cycle protect you later. Many CHTs scramble at renewal time because they completed valid CE activities but cannot locate the certificates or proof of attendance.
What Documentation to Keep
- Certificates of completion: Save digital copies and keep printed copies for any in-person activity.
- Sign-in sheets: For facility in-services, a signed attendance record with date, topic, instructor name, and duration is generally required.
- Transcripts: For college courses or association-based CE, official transcripts or CE transcripts from the issuing organization serve as documentation.
- Program descriptions: Keep a brief record of what each CE activity covered so you can demonstrate domain relevance if audited.
Organizing Your CE File
Create a dedicated digital folder-backed up to cloud storage-organized by renewal cycle year. Within that folder, maintain a simple log spreadsheet listing activity name, provider, date completed, hours claimed, and domain area. When renewal time arrives, this log becomes your submission checklist.
Key Takeaway
Treat every completed CE activity like a receipt you might need to produce later. Filing documentation immediately after completing an activity takes two minutes; hunting for it two years later can take hours-or prove impossible.
Planning Your CE Calendar Strategically
The most effective approach to CE is distributing hours across your renewal cycle rather than cramming them into the final months before expiration. A simple multi-year plan might look like this:
Foundation Domains
- Prioritize Patient Care CE-this reflects 45% of CHT scope and changes most frequently with clinical guidelines
- Attend one nephrology-focused conference or symposium for broad exposure
- Complete at least one Water Treatment module through AAMI-approved content
Regulatory and Safety Focus
- Focus heavily on Infection Control CE-regulatory requirements in this area evolve and carry immediate patient safety implications
- Complete a Machine Technology in-service or biomedical workshop
- Participate in a patient education or preceptor skills course for Domain 5 credit
Renewal Preparation
- Fill any remaining CE hours with content gaps identified from your log
- Review and organize all documentation; confirm total hours against BONENT requirement
- Submit renewal application and fee well before the deadline-processing takes time
If you find that certain domain areas feel rusty as you approach renewal, working through domain-specific practice questions can sharpen your recall before choosing targeted CE. The CHT Exam Prep practice test platform includes questions organized by domain so you can quickly assess where your knowledge needs reinforcement.
Pitfalls That Can Delay Recertification
Several patterns consistently cause problems for CHTs at renewal time. Understanding them in advance is far less stressful than encountering them with a credential expiration looming.
Waiting Until the Final Weeks
CE programs fill up, employers may not approve last-minute conference attendance, and online modules can have technical issues. Building a buffer of completed hours well before the deadline eliminates this category of risk entirely.
Relying on Unapproved Sources
A common mistake is completing CE through a reputable organization without verifying that the specific program carries BONENT approval. Organizational reputation and BONENT approval status are separate things. Always check BONENT's approved provider list directly.
Claiming Hours Inaccurately
CE hours must reflect actual contact time. Claiming eight hours for a six-hour workshop-even if you did optional reading afterward-is falsification. During an audit, inflated claims are immediately apparent when program lengths are compared to reported hours.
Ignoring the Renewal Fee Deadline
CE completion alone does not renew your credential. The formal application and fee must be submitted. Some CHTs complete all required CE but let the renewal lapse because they delayed the application process. Mark the submission deadline on your calendar at least 60 days in advance.
Neglecting Domain Balance
It is tempting to complete CE entirely in your comfort zone-for many technologists, that means Patient Care activities because they feel most immediately applicable. A recertification portfolio that completely ignores Water Treatment or Machine Technology CE, however, may not reflect the comprehensive competence the CHT credential is intended to certify. Domain-balanced CE also keeps you genuinely better prepared for the clinical environment.

Frequently Asked Questions
BONENT's policies on carry-over hours are specific and subject to change. In general, most certifying bodies do not allow unlimited carry-over. Check the current BONENT renewal guidelines directly rather than assuming hours earned this cycle will count toward the next one.
Documented in-facility training can qualify for CE credit if it meets BONENT's criteria-typically including a formal agenda, qualified instructor, defined learning objectives, and verifiable attendance records. Casual shift-based coaching generally does not qualify. Work with your facility educator to ensure in-services are structured to meet BONENT documentation standards.
BONENT will notify you and request documentation for some or all CE activities claimed on your renewal application. You must produce original certificates, transcripts, or sign-in sheets within the specified timeframe. Inability to produce documentation may result in denial of renewal. Technologists who maintain organized CE files from the start of their cycle typically find audits straightforward.
Yes. BONENT offers a recertification-by-examination pathway. This means sitting the full CHT exam again and achieving a passing score in lieu of CE hours. This option is less commonly pursued by active technologists but may be the most practical path for those who have allowed their credential to lapse significantly or who are returning to hemodialysis practice after time away. Preparing through a CHT-specific practice test platform can help you gauge exam readiness before committing to this route.
The five domains-Patient Care, Machine Technology, Water Treatment, Infection Control, and Education and Professional Development-define the full scope of CHT competency. When evaluating a CE activity, ask which domain it addresses. A balanced portfolio spanning all five domains reflects comprehensive professional development and is more defensible during an audit than one concentrated entirely in a single area. Domain-weighted planning, with extra emphasis on Patient Care and Infection Control given their larger shares of the CHT blueprint, gives you a logical framework for CE decision-making throughout the renewal cycle.
