CLIA Personnel Qualifications by Role and Test Complexity
CLIA personnel rules depend on test complexity. Moderate complexity labs need a lab director, technical consultant, clinical consultant and testing personnel. High complexity labs need a director, technical supervisor, clinical consultant, general supervisor and testing personnel. Each role has degree, experience and licensing requirements in 42 CFR 493 Subpart M, last revised December 28, 2024.

Key facts and official sources
Personnel requirements are in 42 CFR 493 Subpart M: §§493.1403–493.1425 for moderate complexity and §§493.1441–493.1495 for high complexity.
Every role requires a current state license where the state requires one.
People who were qualified and serving in a role on December 28, 2024, and have served continuously since, remain qualified for that role (for example §493.1405(b)(6), §493.1411(b)(7), §493.1489(b)(5)).
Surveyors use Form CMS-209, the Laboratory Personnel Report, to review who fills each role.
Which roles does my lab need?
Laboratory director
Moderate complexity: §493.1405
High complexity: §493.1443
Technical consultant
Moderate complexity: §493.1411
High complexity: not used
Technical supervisor
Moderate complexity: not used
High complexity: §493.1449 (specialty-specific)
Clinical consultant
Moderate complexity: §493.1417
High complexity: §493.1455
General supervisor
Moderate complexity: not used
High complexity: §493.1461

One qualified person can hold more than one role. For example, the director may also serve as the technical consultant if they meet that role's qualifications (§493.1407(a), §493.1411).
What are the moderate complexity pathways?
Lab director: Board-certified pathologist; physician with experience and CE; doctoral, master's or bachelor's degree routes with experience and CE. See lab director requirements
Technical consultant: Pathologist; MD/DO/DPM + 1 yr; doctoral or master's + 1 yr; bachelor's + 2 yrs; associate degree in MLT/MLS/CLS + 4 yrs of nonwaived experience in the specialty. See TC qualifications
Clinical consultant: Qualified as a director under §493.1405(b)(1)-(3), or a licensed MD, DO or DPM
Testing personnel: MD/DO; doctoral, master's, bachelor's or associate degree in a lab science, medical technology or nursing; qualifying military training; or a high school diploma with documented training that covers the skills listed in §493.1423(b)(6)
What are the high complexity pathways?
Lab director: Board-certified pathologist; physician with 2 yrs directing or supervising high complexity testing and 20 CE; doctoral degree with board certification, experience and CE
Technical supervisor: Set by specialty and subspecialty in §493.1449. A pathologist certified in both AP and CP covers most specialties. Other routes require experience in the specific specialty
General supervisor: Qualified as a director or technical supervisor; MD/DO/DPM or a doctoral, master's or bachelor's lab science degree + 1 yr high complexity experience; or high complexity testing personnel with an associate degree + 2 yrs
Testing personnel: MD/DO/DPM; doctoral, master's or bachelor's degree in a lab science or medical technology; associate degree in a lab science or MLT, or the defined equivalent with training; or qualifying military training. Nursing degrees are not listed by name. A nurse may still qualify through the coursework and training equivalency in §493.1489(b)(3)(ii)
What is Form CMS-209?
Form CMS-209, the Laboratory Personnel Report (CLIA), lists the people responsible for testing and the CLIA positions they hold. Surveyors use it to check that each required position is filled by a qualified person. Keep it current whenever staff change.
How do you document qualifications for a survey?
Keep a file for each person containing:
diploma or transcript (with a foreign degree equivalency evaluation if applicable)
state license, if required
board certification, if used
experience letters showing nonwaived or high complexity work
CE certificates, if used
training records and competency assessments
Missing transcripts and undocumented experience are common reasons a qualification can't be verified.
Frequently asked questions
Can one person fill multiple CLIA roles?
Yes, if they meet the qualifications for each role. The director remains responsible for any duties they delegate.
Can a nurse perform moderate complexity testing?
Yes. §493.1423 lists bachelor's and associate degrees in nursing as qualifying for moderate complexity testing personnel. For high complexity testing, §493.1489 does not list nursing degrees by name. A nurse would need to meet another pathway, such as the coursework and training equivalency in §493.1489(b)(3)(ii).
Do waived labs have personnel requirements?
CLIA sets no federal personnel qualifications for Certificate of Waiver labs. Some states and accreditors do.
Are current staff grandfathered after the 2024 changes?
Yes, if they were qualified and serving in that role on December 28, 2024, and have served continuously since.
Need a personnel file audit?
Sound Lab Consultants reviews personnel files against Subpart M, fills lab director and technical consultant roles, and prepares labs for surveys.
