Phlebotomy Competency Checklist: What Supervisors Evaluate

April 9, 2026·6 min read·By PhlebotomySkills Editorial Team,

Every phlebotomist working in a CLIA-regulated laboratory setting undergoes competency assessment. Federal law (42 CFR Part 493) requires facilities to evaluate non-waived testing personnel at defined intervals. Phlebotomists are included. Here’s what supervisors are actually measuring and how to perform at the top level on each criterion.

Why Competency Assessments Exist

CLIA (Clinical Laboratory Improvement Amendments) requires laboratory directors to verify that all testing personnel, including those who collect specimens, remain competent. Initial competency is assessed during orientation/training. Ongoing competency is assessed at least once in the first year and at least annually after that.

Competency assessment is not punitive in a well-run lab. It’s a structured way to identify training needs before they become patient safety events. A phlebotomist who passes competency assessment every year has documentation that they are performing within established standards.

The Six CLIA Competency Assessment Methods

CLIA specifies six methods that can be used for competency assessment. Supervisors select from these based on the role being evaluated:

1. Direct observation of routine patient care: Supervisor or designee watches the phlebotomist perform an actual patient draw and documents performance against a checklist.

2. Monitoring the recording and reporting of results: Evaluates documentation accuracy, draw times, labels, LIS entries.

3. Review of intermediate test results: In a phlebotomy context: reviewing specimen rejection rates, QNS events, and hemolysis rates attributable to a specific collector.

4. Direct observation of performance of instrument maintenance and function checks: Centrifuge maintenance, point-of-care device QC, calibration records.

5. Assessment of test performance using blind samples, proficiency testing materials, or QC samples: Less common for phlebotomy; more relevant for testing personnel.

6. Evaluation of problem-solving skills: Written or verbal assessment of how the phlebotomist handles non-routine situations (patient refusal, ambiguous order, suspected specimen contamination).

What a Phlebotomy Competency Checklist Covers

Direct observation during a patient draw is the most common competency assessment method for phlebotomists. A standard checklist will include most or all of the following:

Patient Identification

Does the phlebotomist ask the patient to state their full name and date of birth (not just confirm it)? Does the phlebotomist compare the patient response against the wristband (inpatient) or requisition (outpatient)? Is identification performed before any clinical interaction?

How to excel: Make identification the first thing you do, every time, even for patients you recognize. Evaluators are watching for this specifically because it’s the most consequential safety step.

Order Review and Tube Selection

Does the phlebotomist review the order before approaching the patient? Are the correct tubes selected for the ordered tests? Are the tubes laid out in the correct order of draw before the patient is approached?

How to excel: Prepare your supplies at the supply cart, never at the patient’s arm. Evaluators notice when a phlebotomist is fumbling for tubes after the tourniquet is already on.

Hand Hygiene

Is hand hygiene performed before glove application and after removing gloves? Is the method correct (soap and water or alcohol-based sanitizer, adequate coverage)?

Tourniquet Application

Is the tourniquet applied at the correct distance from the site? Is it tight enough for venous engorgement but not arterially occlusive? Is it released within 1 minute?

Site Preparation

Is the correct antiseptic used? Is the alcohol allowed to fully air dry before needle insertion? Is the site re-contaminated after cleaning (touching, waving)?

Needle Insertion Technique

Is the vein anchored before insertion? Is the bevel up? Is the entry angle appropriate (15-30°)? Is the needle inserted smoothly without multiple re-insertions?

Tube Collection

Are tubes collected in the correct order of draw? Is each tube mixed by the correct number of inversions immediately after removal? Is mixing gentle (no shaking)?

Needle Withdrawal and Pressure

Is the tourniquet released before withdrawal? Is gauze placed over the site before (not during) withdrawal? Is the safety device activated immediately after withdrawal? Is the needle disposed of directly into the sharps container?

Specimen Labeling

Are labels applied at the bedside, in the patient’s presence? Do labels contain all required elements (name, DOB/MRN, date and time of collection, collector ID)? Are labels applied to the correct tubes?

Patient Care Post-Draw

Is the patient assessed for bleeding cessation before leaving? Is the bandage applied? Is the patient informed of any relevant instructions? Is the patient asked how they feel?

Documentation

Is the draw time documented accurately? Are any collection complications documented in the LIS?

How Annual Competency Differs from Initial Training Assessment

Initial competency during training covers basic technique under direct supervision with most draws observed. Annual competency assessments are typically less intensive: one or two observed draws per year plus a review of the phlebotomist’s performance metrics (rejection rate, labeling error rate, incident history).

The highest-performing phlebotomists maintain their technique consistently, the annual assessment is just a confirmation of what supervisors see every day. Phlebotomists who drift into bad habits between assessments (skipping hand hygiene when they think no one is watching, labeling tubes at the station instead of bedside) are the ones who struggle during observed assessments.

If You Don’t Pass

A failed competency assessment triggers a remediation plan, not immediate termination in most facilities. The remediation process typically includes: identifying the specific deficient areas, additional training or supervised practice, and re-evaluation within a defined timeframe (usually 30-90 days).

If you fail an item on your competency checklist, the most effective response is direct acknowledgment and a commitment to the specific correction. Defending the failed behavior or minimizing the concern makes remediation harder and damages your relationship with your supervisor.

Preparing for Your Assessment

Review the order of draw and tube mixing requirements the day before a scheduled competency observation. Run through the patient interaction steps mentally: ID verification → order review → hand hygiene → supply prep → tourniquet → site selection → antiseptic and dry time → anchor and insert → tubes in order → invert → tourniquet release → withdraw → safety device → sharps disposal → pressure → label at bedside → document.

If you’re preparing for ASCP PBT certification, the clinical knowledge tested on the exam aligns directly with the competency evaluation criteria, they assess the same body of knowledge.
