CLIA Personnel Requirements by Test Complexity
Personnel qualifications are one of the four findings a surveyor must cite at condition level, harm or no harm. Subpart M sets a different bar for each role at each complexity level, and the rules in force since December 28, 2024 added semester-hour equivalency routes. Here is every role but the director, in one table, from the current eCFR text.
Which roles each certificate needs
Subpart M makes each role a condition of the certificate. The complexity of your hardest test decides the column of roles you must fill; one person may fill several if they qualify for each.
- required role
- not a CLIA role at this level
| Role | Waived | PPM | Moderate | High |
|---|---|---|---|---|
| Laboratory director | requiredCMS | required§ 493.1355 | required§ 493.1403 | required§ 493.1441 |
| Technical consultant | not a CLIA role at this level | not a CLIA role at this level | required§ 493.1409 | not a CLIA role at this level |
| Clinical consultant | not a CLIA role at this level | not a CLIA role at this level | required§ 493.1415 | required§ 493.1453 |
| Technical supervisor | not a CLIA role at this level | not a CLIA role at this level | not a CLIA role at this level | required§ 493.1447 |
| General supervisor | not a CLIA role at this level | not a CLIA role at this level | not a CLIA role at this level | required§ 493.1459 |
| Testing personnel | not a CLIA role at this level | required§ 493.1361 | required§ 493.1421 | required§ 493.1487 |
Subpart M covers nonwaived testing only: a certificate of waiver lab needs a director with no federal qualifications and sets no federal bar for testers. High complexity cytology adds a cytology general supervisor (§ 493.1467) and cytotechnologists (§ 493.1481).
Qualifications by role and complexity
Every route below also needs a current State license where your State licenses that role (paragraph (a) of each section). The text is subpart M as amended by the December 2023 final rule, in force since December 28, 2024. “Lab science” is the rule's “chemical, biological, clinical or medical laboratory science, or medical technology”; years are laboratory training or experience, or both.
| Role | Moderate complexity | High complexity |
|---|---|---|
| Technical consultant |
| No technical consultant at high complexity: the technical supervisor holds that ground. |
| Clinical consultant |
|
|
| Technical supervisor | Not a moderate complexity role: the technical consultant covers it. |
|
| General supervisor | Not a moderate complexity role. |
|
| Testing personnel |
|

PPM testing is narrower still: only a physician, a midlevel practitioner (supervised by a physician, or independent where the State allows) or a dentist may perform it, personally, during the patient's visit (§ 493.1363, § 493.1365). The director qualifications at every level are in the lab director requirements guide.
Two details catch labs out. Nursing degrees qualify for moderate complexity testing but are not listed for high complexity testing. And the moderate high-school route (§ 493.1423(b)(6)) requires the training to be documented before the person analyzes a patient specimen, covering specimen handling, procedures, instrument use, maintenance and calibration, reagent stability, QC, the factors that affect results, and checking QC before reporting.
Degree equivalency rules
A degree in another subject can still count. Since December 28, 2024 the rule spells out, in semester hours, what stands in for a lab science degree at each level. The other roles point back to these routes in § 493.1405 rather than repeat them.
| Stands in for | What the rule asks | Where |
|---|---|---|
| Doctoral | Any earned doctoral degree plus at least 16 semester hours of doctoral-level coursework in biology, chemistry, MT, CLS or MLS, or an approved thesis or research project in those fields related to laboratory testing | § 493.1405(b)(3)(i)(B) |
| Master's | Bachelor's degree equivalency plus at least 16 semester hours of additional graduate coursework in biology, chemistry, MT, CLS or MLS, or 16 semester hours combining that coursework with an approved thesis or research project | § 493.1405(b)(4)(i)(B)–(C) |
| Bachelor's | At least 120 semester hours, including either 48 semester hours of medical laboratory science or technology courses, or 48 semester hours of science: 12 of chemistry (general chemistry and biochemistry or organic chemistry), 12 of biology (general biology and molecular biology, cell biology or genetics) and 24 more in any combination | § 493.1405(b)(5)(i)(B) |
| Associate (high complexity testing) | At least 60 semester hours, including 24 of medical laboratory technology courses, or 24 of science (6 chemistry, 6 biology, 12 in any combination), plus an ABHES- or CAAHEP-accredited clinical training program or at least 3 months of documented training in each specialty tested | § 493.1489(b)(3)(ii) |
“Doctoral degree” is defined in § 493.2: at least 3 years of graduate study including research related to clinical laboratory testing or advanced study in a laboratory science. MD, DO, DPM, DVM and honorary degrees are excluded. Degrees from abroad count when HHS or its designee finds the foreign institution meets substantially equivalent requirements; keep the evidence of that in the personnel file.
CMS clarified in June 2025 that the thesis or research project in these routes “does not need to be on human subjects” (QSO-25-21-CLIA).
What counts as training or experience
The years in the table are not any years in a lab. § 493.2 requires them to be gained in a facility that meets CLIA's definition of a laboratory and is not excepted under § 493.3. Forensic-only testing, research labs that report no patient-specific results, and SAMHSA-certified drug testing are the exceptions. Technical consultant and supervisor years must also be in the specialty or subspecialty the person will oversee.
The technical consultant requirements for “laboratory training or experience, or both” in each specialty or subspecialty may be acquired concurrently in more than one of the specialties or subspecialties of service, excluding waived tests.
The rule's own example: a biology graduate with documented 2 years of moderate complexity testing across all specialties qualifies as technical consultant in all of them. Waived testing does not count: the paths ask for nonwaived or high complexity testing. Keep the evidence: letters from prior employers naming the specialties and dates, not a CV line.
Takeaway
Who must be on site, and when
Presence, by role
- Technical consultant: not on site at all times; reachable on site, by phone or electronically§ 493.1413(a)
- Technical supervisor: the same, at high complexity§ 493.1451(a)
- General supervisor: reachable by testing staff at all times testing is performed§ 493.1463(a)(1)
- Director: on site at least once every 6 months, 4 months apart§ 493.1407(c)
Testing personnel at either level run only the tests the director has authorized for them, at a skill that matches their education, training or experience (§ 493.1425(a), § 493.1495(a)). That authorization is the written duty list a surveyor will ask for. A tester who finds a problem they cannot fix must tell the technical consultant, clinical consultant or director at moderate complexity, and the general supervisor, technical supervisor, clinical consultant or director at high.
Staff serving on 28 December 2024
Each role carries a paragraph that keeps people already in post: anyone “qualified and serving” in that role in a CLIA-certified lab as of December 28, 2024, “and have done so continuously since”. It sits at § 493.1411(b)(7), § 493.1423(b)(8), § 493.1449(j), § 493.1461(c)(4), § 493.1483(b)(3) and § 493.1489(b)(5).
The clinical consultant sections, § 493.1417 and § 493.1455, have no such paragraph. CMS's June 2025 memo says anyone previously qualified as a clinical consultant continues to qualify without extra CE hours (QSO-25-21-CLIA), and the October 2026 proposal would write a grandfather paragraph in.
“Continuously” is the word to protect. Keep a dated record showing the person held the role on December 28, 2024 and every month since; a lapse leaves them to meet today's routes.
Qualified is not the same as competent
Qualifications get someone in the door; competency keeps them testing. The technical consultant (moderate) or technical supervisor (high) assesses every tester, twice in their first year and yearly after, and a high complexity lab may delegate that in writing to a general supervisor (§ 493.1463(b)(4)).
Takeaway
What the October 2026 proposal would change
Proposed, not law
CMS-3478-P was published on 8 October 2026; comments are due 7 December 2026. None of it applies until a final rule is published. The table above is today's text, and it is what a surveyor cites.
For roles other than the director, the proposed rule would:
- define biological, chemical and laboratory science degrees by federal education program codes, widening them to include animal and veterinary sciences and removing the “human-only” limits;
- add qualifications for histopathology gross tissue examination personnel;
- let associate-degree technical consultants (§ 493.1411(b)(5)) cover blood gas analysis;
- add a grandfather paragraph for clinical consultants;
- let a general supervisor be delegated competency assessment of both moderate and high complexity testers;
- rewrite cross-references in the high complexity testing personnel routes and confirm that an associate degree in a chemical or biological science qualifies.
CMS says the changes “would not change CLIA regulatory requirements related to personnel training, annual competency assessment, quality systems, PT, and biennial on-site surveys”.
Staffing a small lab
CMS answers “No” to whether each position needs a different person: one person may hold several roles if they meet each role's qualifications (CMS director brochure). A typical moderate complexity practice lab fills the chart like this:
- the physician-director also serves as clinical consultant, since any licensed MD, DO or DPM qualifies (§ 493.1417(b));
- a technical consultant with a lab science degree and, depending on the degree, 1 to 4 years in each specialty tested, often under contract;
- testers with a degree, or a high school diploma and documented training, for moderate complexity work only.
The technical consultant is usually the hard hire, because the years must be in the specialties on your menu. Adding one high complexity test changes the chart: a technical supervisor and a general supervisor, and no high school route for the testers.
