Who Can Assess Whom? A Practical Guide to CLIA Competency Assessment Requirements

Competency assessment is one of the most cited deficiency areas during laboratory inspections, not because labs don’t have a program, but because the program they have doesn’t hold up under review. The documentation exists. The checklists are signed. But when a surveyor starts asking who performed the assessment, whether that person was qualified to do so, and whether every test system was covered for every staff member, that’s where programs quietly fall apart. For most labs, the gap isn’t awareness. It’s the details.

Those details were at the heart of a recent webinar hosted by MediaLab by Vastian, featuring Dr. Alec Saitman, PhD, DABCC, Associate Professor of Pathology and Laboratory Medicine and Director of Chemistry and Toxicology at Oregon Health and Science University. This post distills the key takeaways, with a particular focus on the "who can assess whom" question that trips up so many labs during inspections.

The Six Elements of Competency: A Quick Refresher

CLIA requires that competency assessment cover six specific elements for moderate and high complexity testing. These are:

1. Direct observation of routine test performance — watching the perform do the work in real time

2. Monitoring, recording, and reporting of results — verifying accurate documentation, critical value reporting, and data integrity

3. Review of QC, PT, and maintenance records — checking that the tech understands and acts appropriately on quality data

4. Direct observation of instrument maintenance — this one is easy to shortcut by relying on maintenance logs alone, but CLIA requires the assessor to observe the process directly

5. Assessment of test performance — typically using blinded or previously tested specimens to evaluate accuracy

6. Assessment of problem-solving skills — evaluating the tech's ability to troubleshoot, investigate QC failures, and respond to instrument issues

All six elements need to be documented. A signature on a checklist alone doesn't cut it, and inspectors know the difference.

The Big Question: Who Can Perform Competency Assessment?

This is where most labs have at least one gap they don’t know about yet. CLIA distinguishes between the requirements for waived testing, moderate complexity testing, and high complexity testing, and the rules around who can assess staff are different for each.

Waived Testing

Let's start with the honest answer—waived testing is complicated. CLIA does not require formal competency assessment for waived testing in the same way it does for moderate and high complexity testing. However, many accrediting bodies (CAP, TJC, COLA) do have requirements or strong recommendations for waived testing competency. Dr. Saitman put it well: "Is it best practice to include competency assessment for waived testing? Absolutely. Is it required? It depends." The bottom line: check directly with your accrediting body for specifics on waived testing, because the answer isn't one-size-fits-all.

Moderate Complexity Testing

For moderate complexity testing, CLIA requires that competency assessment be performed by, or at a minimum overseen by, someone who qualifies as a Technical Consultant (TC).

According to CLIA CFR §493.1413, a Technical Consultant for moderate complexity testing must meet at least one of several qualification pathways, the most common being:

• A bachelor's degree in a chemical, physical, biological, or clinical laboratory science, or medical technology, from an accredited institution

• At least 2 years of laboratory training or experience (or both) in non-waived testing in the specialty in which they are functioning

In practice, this means many experienced bench technologists in your lab may already meet TC qualifications; they just need to be formally recognized and delegated by your CLIA director. That's a significant opportunity. One person doesn't have to carry out the entire competency assessment burden for a whole department.

High Complexity Testing

The bar is higher for high complexity testing. CLIA requires that competency assessment be performed by or delegated to someone who qualifies as a Technical Supervisor (TS).

Under CLIA CFR §493.1461, a Technical Supervisor for high complexity testing typically requires:

• A bachelor's degree in a chemical, physical, biological, or clinical laboratory science, or medical technology

• At least 4 years of laboratory training or experience (or both) in the specialty in which they are supervising

Again, the CLIA director can delegate TS responsibilities to qualified staff. This is especially critical in larger labs where expecting a single TS to personally assess dozens of technologists across 20+ test systems simply isn't operationally realistic.

One additional nuance worth knowing: for high complexity testing, CLIA also recognizes a General Supervisor (GS) role. A General Supervisor can perform competency assessments if they have been formally delegated in writing by the Technical Supervisor and meet the GS qualifications under §493.1463. In moderate complexity, there is no equivalent GS designation defined in the same way, so the TC pathway is the relevant standard.

One Rule for Everyone: No Self-Assessment

Regardless of complexity level, this is non-negotiable — competency oversight must be independent. An assessor cannot assess themselves. If an inspector finds documentation of a Technical Supervisor or Technical Consultant performing their own competency assessment, that's a deficiency. No exceptions.

In small labs where only one TS or TC exists, this can feel like a catch-22. The solution is either to have the laboratory director step in as the assessor or to establish an external arrangement—bringing in a qualified professional from another lab or site (on a different CLIA license) to close that loop. It's worth building this into your policy before you need it, not after.

When Should Competency Assessment Happen? A Career Timeline

Timing is almost as important as the assessment itself. Here's how CLIA frames the expected schedule:

Year One: Initial Competencies (Twice)

For any staff member performing non-waived testing, CLIA requires two competency assessments during the first year of testing. The commonly used benchmarks are 6 months and 12 months, but there's a bit of regulatory breathing room. CAP Checklist GEN.55505 specifies that the first assessment should be completed within the first 7 months of starting testing, and the second no later than 12 months. That flexibility is intentional and useful.

As Dr. Saitman noted, "Three competencies within the first two years" is the right way to think about it — two in year one, then annually thereafter.

Year Two and Beyond: Annual Competency

After the first year, every staff member who performs testing on a given test system must have a competency assessment completed at least annually. This applies to every test system they're trained on, not just their "primary" area. If a generalist tech rotates through hematology, chemistry, and urinalysis, they need annual assessments for all three.

Other Triggering Events

Outside of the standard schedule, competency assessment should also be considered when:

• A new method, instrument, or procedure is introduced

• A staff member takes on new testing responsibilities

• A staff member returns from extended leave (FMLA, medical leave, etc.) — particularly if the absence was long enough to warrant retraining before reassessment

• A competency gap is identified and remediation has been completed

It's good practice to build these triggers into your competency policy, so there's no ambiguity about when a special assessment is required.

Case Study: The 20×20 Problem

This is one of the most common patterns we see across labs for all sizes.

A mid-sized community hospital laboratory employs 20 technologists and has defined 20 test systems across its departments — hematology, chemistry, coagulation, urinalysis, point-of-care glucose meters, blood gas, and several others. The lab has one Technical Supervisor who has historically been responsible for all competency assessments.

Each assessment takes approximately 30 minutes. That's 20 techs × 20 test systems × 30 minutes = 200 hours of assessment time per year, not counting scheduling coordination, documentation, or follow-up.

On top of that, the TS also runs the morning shift, troubleshoots instrument issues, reviews QC, and manages reagent inventory.

The result? Competency assessments start slipping. Some get done late. Some are rushed. A few techs' assessments expired during a stretch when the TS was on vacation. During the next inspection, the surveyor finds multiple overdue competencies and documentation gaps.

What could this lab do differently?

First, identify which staff members already qualify as Technical Supervisors based on their education and experience. In a lab of 20 technologists, several are likely to meet the bachelor's degree + 4-year experience threshold. With formal delegation from the CLIA director, multiple TCs and TSs can be designated for specific test systems or departments.

Second, stagger competency assessments throughout the year by test system rather than trying to complete everything at once. This distributes the workload, keeps assessors focused, and prevents the "November-December competency crunch" that Dr. Saitman specifically called out as something to avoid.

Third, build a standardized competency template that covers all six elements and semi-customize it for each test system. This reduces the cognitive load on assessors and makes documentation more consistent and inspection-ready.

By distributing ownership and building structure into the program, this lab could turn a 200-hour annual burden into a manageable, year-round process.

A Few Things That Often Get Overlooked

Assess your assessors. CLIA doesn't explicitly require competency assessment of assessors in their evaluator role, but it is considered best practice. More importantly, if your assessors also perform bench duties, they absolutely must have their own competency assessments completed by another qualified individual.

Document the "why" behind your test system definitions. One of the most common inspection gaps isn't the competency assessment itself; it's the lack of clarity around how test systems are defined. When your lab can show an inspector that you've been intentional and methodical about defining test systems based on workflow, technology, and decision-making differences, that's a sign of a well-run program.

Don't forget the manual methods. Automated platforms get most of the attention, but manual methods are often the most overlooked area when it comes to competency. QC processes, frequency of performance, and procedural compliance for manual tests deserve the same rigor as any instrument-based assay.
