What the CLT-LANA Credential Actually Is
The CLT-LANA designation stands for LANA Certified Lymphedema Therapist. It is issued by the Lymphology Association of North America (LANA), the professional body that sets the standard for lymphedema therapy practice and credentialing in North America. It is not a course completion certificate. A training program teaches you complete decongestive therapy (CDT); the LANA credential is an independent, third-party verification that you meet an established competency standard, verified through a closed-book proficiency examination.
That distinction matters when you read job postings. Employers who ask for "CLT-LANA" are asking for the credential itself, not just proof that you attended a course. If you are still orienting yourself, our explainers on what CLT-LANA certification is and what CLT-LANA stands for cover the basics, and the broader CLT-LANA certification overview sits alongside this guide.
The Three Eligibility Gates
You cannot simply register and sit for the exam. LANA requires candidates to clear three separate gates before they are approved. Missing any one of them stalls your application, so it pays to audit them early. The full details live in our CLT-LANA requirements guide; here is the working summary.
Gate 1: Qualifying Professional Credential
Candidates must hold an accepted professional license, registration, or equivalent qualifying credential. This is the foundation of the pathway, and it is also what you must keep current to renew later.
- Confirm your specific license type is on LANA's accepted list before investing in training
- Keep proof of licensure ready for the application
Gate 2: 135 Hours of Qualifying CDT Training
You need at least 135 hours of qualifying complete decongestive therapy training that includes an in-person skills assessment. Hands-on competence in techniques such as manual lymph drainage and compression bandaging cannot be certified from a screen alone.
- LANA's April 2026 policy allows remote theoretical instruction
- The practical laboratory component must still be delivered on-site
- Verify that your program's hours and format meet the standard before enrolling
Gate 3: 12 College Science Credit Hours
Candidates need 12 college science credit hours, with specified exemptions for certain professional licensures. If your licensure pathway already covers this foundation, you may be exempt; if not, plan for the coursework well ahead of your target exam window.
- Check whether your license qualifies for an exemption
- Gather transcripts early, since documentation delays are common

Exam Format: What Sitting Down Looks Like
The exam is English-language and closed book. You answer 130 multiple-choice questions, each with four options and exactly one correct answer, in 150 minutes. That works out to a little over a minute per question, which is comfortable for knowledge recall but tighter for lengthy case-style stems.
| Exam Feature | CLT-LANA Detail |
|---|---|
| Certifying body | Lymphology Association of North America (LANA) |
| Total questions | 130 four-option, single-answer multiple choice |
| Scored questions | 110 |
| Unscored research items | 20 (unidentified) |
| Testing time | 150 minutes |
| Passing standard | Scaled score of 700 out of 1000 |
| Delivery | Prometric-supported test center or approved remote proctoring |
| Reference materials | None (closed book) |
The 20 Unidentified Research Items
Twenty of the 130 questions are research items that do not count toward your result, but you are not told which ones. Do not try to guess which questions are "the throwaways." Candidates who spend time hunting for them tend to rush the real ones. Answer every question with full effort.
Why the Scaled Score Is Not 70%
A scaled score of 700 out of 1000 is not the same as getting 70% of questions right. Scaling accounts for differences in difficulty across exam forms, so the raw number of correct answers needed can vary. Our passing score guide explains the mechanics in more detail. The practical takeaway: do not budget your preparation around a raw-percentage target, and do not assume you can "afford" to miss a specific number of questions.
The Four-Domain Content Blueprint
The exam is built on four domains. Two of them carry 30% each, which means 60% of your score comes from disorders and management combined. Our complete domains guide goes deeper on each area; this section highlights the highest-value content in each.
| Domain | Weight |
|---|---|
| Domain 1: Anatomy and Physiology | 25% |
| Domain 2: Lymphedema, Vascular, and Related Disorders | 30% |
| Domain 3: Patient Evaluation and Treatment Planning | 15% |
| Domain 4: Management of Lymphedema and Related Disorders | 30% |
Domain 1: Anatomy and Physiology (25%)
This is the vocabulary and mechanism layer that every other domain builds on. Expect questions that ask you to reason about why fluid accumulates and where it drains, not simply to label structures.
- Lymphatic vessel hierarchy: initial lymphatics, collectors, trunks, and ducts
- Lymph nodes, drainage territories, and watersheds
- Starling forces and how filtration and reabsorption balance in healthy tissue
- Lymph formation, lymphatic load, and transport capacity
- Interaction between the lymphatic, venous, and arterial systems
Domain 2: Lymphedema, Vascular, and Related Disorders (30%)
One of the two heaviest domains. The key skill is differentiation: telling lymphedema apart from the conditions that mimic it or coexist with it, because management and safety precautions change depending on the diagnosis.
- Primary versus secondary lymphedema, including causes and typical presentation
- Fat disorders such as lipedema and how they differ from lymphedema
- Venous and arteriovenous disease, including chronic venous insufficiency
- Related disorders that produce edema and the red flags that call for medical referral
- Complications such as infection (cellulitis) and tissue changes in chronic disease
Domain 3: Patient Evaluation and Treatment Planning (15%)
The smallest domain, but the one that connects knowledge to clinical judgment. Questions often present a patient scenario and ask what you should assess or prioritize first.
- History taking and identifying contraindications before treatment
- Limb measurement methods and tracking change over time
- Skin and tissue assessment, including staging and severity
- Building a treatment plan aligned with the patient's goals and comorbidities
Domain 4: Management of Lymphedema and Related Disorders (30%)
The other heavyweight. This is where complete decongestive therapy lives, and where application-level questions tend to concentrate.
- The phases and components of CDT: manual lymph drainage, compression, exercise, and skin care
- Compression bandaging versus garments, and when each is appropriate
- Adapting care when a patient has cardiac, renal, vascular, or infection-related concerns
- Patient self-management education and long-term maintenance
- Recognizing when to modify, pause, or refer rather than proceed
Key Takeaway
Do not treat Domain 3 as skippable because it is the smallest. Its scenario-style thinking shows up inside Domain 2 and Domain 4 questions too. Safety and contraindication reasoning is a thread running through the entire exam.

Fees, Scheduling, and Retake Rules
The cost structure has a time-sensitive element worth planning around. The exam fee is currently $430 and increases to $480 on April 1, 2027. Recertification costs $200 and increases to $250 on January 1, 2027. If your timeline is flexible, applying before the increase takes effect saves money. Our certification cost breakdown adds the surrounding training and preparation costs, and the exam dates guide covers testing windows and deadlines.
| Fee | Current | Scheduled Increase |
|---|---|---|
| Exam fee | $430 | $480 on April 1, 2027 |
| Recertification fee | $200 | $250 on January 1, 2027 |
Retake Policy
The retake rules reward getting it right the first time. After an unsuccessful attempt, you must wait six months before retesting. You may attempt the exam a maximum of three times within 24 months. If you fail three times, an additional 12-month wait applies. This is a much longer gap than many certification exams impose, so a failed attempt can cost you most of a year of career momentum.
Sequencing Your Preparation Around the Weighting
You do not need an elaborate method. You need to match your time to the blueprint. Because Domains 2 and 4 together account for 60% of scored content, they deserve the largest share of your hours, and because Domain 1 underpins everything, it should come first. A sensible order looks like this. For a full plan, see our CLT-LANA study guide.
Build the Foundation (Domain 1)
- Master lymphatic anatomy, drainage territories, and fluid dynamics
- Draw the vessel hierarchy from memory until it is automatic
- Reason through Starling forces instead of memorizing them
Disorders and Differentiation (Domain 2)
- Build comparison charts: lymphedema vs. lipedema vs. venous disease
- Memorize red flags that require referral
- Practice distinguishing primary from secondary causes
Management and Application (Domains 3 and 4)
- Walk through CDT components and indications for each
- Drill contraindications and when to modify or refer
- Work scenario questions on evaluation and treatment planning
Integration and Timed Practice
- Take full-length timed sets at the 150-minute pace
- Review misses by domain to find any remaining weak spots
- Skim the cheat sheet and rest before exam day
The reasoning behind this order: Domain 1 knowledge makes the pathophysiology in Domain 2 stick, and Domain 2 diagnosis logic makes the management decisions in Domain 4 make sense. Studying them in reverse tends to produce memorized steps without the understanding to apply them to unfamiliar scenarios. You can test yourself against original questions in our CLT-LANA practice test.
Keeping the Credential Active
CLT-LANA certification renews every six years. To renew, you complete 24 contact hours of qualifying education or other approved activities, or you may choose re-examination. You must also hold a current qualifying professional credential and pay the renewal fee. Because the qualifying professional license is a condition of renewal, letting that license lapse can put your certification at risk even if your education hours are complete.
Key Takeaway
Track your contact hours as you earn them rather than scrambling in year six. Keep the certificates, and keep your underlying professional license current. Both are required, not either-or.
Where the Credential Gets You Hired
Lymphedema therapists are most commonly employed in settings where patients with chronic edema, post-cancer swelling, and vascular conditions are treated. These typically include outpatient rehabilitation clinics, hospital-based oncology and surgical programs, wound care centers, and specialized lymphedema practices. Many therapists also work in home health, skilled nursing, or private practice, often combining the credential with an existing physical therapy, occupational therapy, or nursing background.
Because eligibility depends on holding a qualifying professional license, the credential generally functions as a specialization layered on top of an existing clinical role rather than a standalone entry point. That is a key reason employers value it: it signals verified competence in a niche that general training does not cover in depth.

Frequently Asked Questions
The Lymphology Association of North America (LANA) issues it. Prometric supports exam administration through test centers and approved remote proctoring, but LANA is the certifying body.
The exam has 130 four-option, single-answer multiple-choice questions. Of those, 110 are scored and 20 are unidentified research items that do not affect your result. You have 150 minutes to complete it.
You need a scaled score of 700 out of 1000. This is not the same as answering 70% of questions correctly, because scaling adjusts for difficulty differences between exam forms.
You must wait six months before retaking. You can attempt the exam up to three times within 24 months, and after three failures an additional 12-month wait applies.
Not entirely. LANA's April 2026 policy permits remote theoretical instruction, but the practical laboratory instruction and skills assessment must be completed on-site and in person, as part of the required 135 hours.
Whatever your starting point, the clearest path is to confirm eligibility first, lock in the domains that carry the most weight, and give yourself enough runway to avoid the long retake wait. When you are ready to measure your readiness, work through our original questions in the CLT-LANA practice exam, an independent preparation resource built around the four official content domains.
