In almost every lab, at some point—usually during an audit—somebody realizes that a procedure has been done a certain way for years, by multiple people, and nobody can quite trace it back to a written standard. It just became “how we do it.” The original rationale may have gotten lost somewhere between staff turnover and the assumption that institutional knowledge would get passed on.
Accreditation frameworks, such as ISO/IEC 17025, exist partly to prevent such drifts, but they alone cannot curb procedural entropy. It depends largely on lab professionals who stay engaged in continuous learning, remain current with industry developments, and apply that knowledge to improve day-to-day laboratory practices
Accreditation Isn’t a Destination
The framing around lab accreditation tends to emphasize achievement. It is, indeed, a meaningful milestone, and the process warrants a useful level of rigor in documentation, method validation, and personnel competency. But accreditation bodies don’t operate on a single-pass model, and for good reasons. Standards get revised. Methods evolve. Regulatory requirements shift.
What was technically sufficient practice three years ago may fall short of current expectations in ways that may not be obvious until an assessor points them out. The gap between where your lab’s practices are and where they need to be tends to widen quietly. Continuous learning keeps that gap from forming in the first place.
The Competency Question Nobody Asks Enough
Most labs have some form of training documentation. New analysts go through an onboarding process and may perform proficiency testing (PT) on key methods. The paperwork gets filed, and the auditors see a training record and check a box.
What’s harder to document and assess is whether that training translated into competent, current practice. There’s a meaningful difference between someone who completed training on a method two years ago and someone who understands it well enough to catch a problem when the results look slightly off or recognize sample matrix anomalies.
Deep competency and expertise develop when the lab staff can consistently engage with the discipline, read current literature, attend technical workshops, participate in PT programs, and interact with peers at other facilities facing similar challenges. These practices help build, maintain, and hone professional judgment over time.
ISO/IEC 17025:2017 is fairly explicit about this in its requirements around personnel competency. The standard calls for labs to have processes to monitor competency on an ongoing basis, not just at hire or during initial training. Most labs don’t fully know what “monitoring” looks like beyond the initial sign-off.
Continuous Learning in Practice
What continuous learning actually looks like in the real world varies significantly with lab size, sector, and available resources. A large pharmaceutical testing lab may have different options than a small environmental monitoring facility. But some patterns hold across contexts.
Structured continuing education is mostly sought through professional associations, accreditation bodies’ in-house training programs, or academic courses. However, the informal mechanisms are unconventional but often more immediately useful. They could be:
- regular internal knowledge-sharing sessions where analysts present on what they’ve been reading or encountered in their work,
- post-incident reviews that dig into root causes rather than just corrective actions, and/or
- leveraging PT results as teaching material and not just as compliance evidence.
The last point is underused: A PT sample where your lab’s result sits at the edge of the acceptable range isn’t a near-miss to file away. Many laboratories use these situations as opportunities to review variability, strengthen internal processes, and improve consistency in future testing rounds.
Laboratory management’s commitment is vital to facilitating such informal learning mechanisms. Analysts don’t build time for professional development into their schedules when the leadership implicitly prioritizes throughput. When labs actively budget for training, conference attendance, and participation in technical working groups, and when managers themselves model engagement with current developments in the field, the culture around learning shifts noticeably.
The Staff Turnover Problem
One thing that doesn’t get discussed enough in the context of lab quality is how much tacit knowledge leaves when experienced personnel are at work. This is a real structural challenge in many labs, particularly smaller operations, where a few senior analysts carry a disproportionate share of institutional expertise.
Continuous learning helps in two ways:
- Labs that invest in the development of junior and mid-level staff build broader organizational competency, reducing dependence on specific individuals.
- Incorporating reasoning in systematic documentation practices, and not just procedures, facilitates knowledge transfer. Addressing why a method was validated a certain way or what problems the current approach was designed to solve, etc., helps understand concepts in ways that informal mentorship doesn’t.
When staff turnover, as they inevitably do, what matters is how much of what they know stays in the lab with them.
Connection to Client Confidence
Labs tend to think about accreditation primarily in terms of regulatory compliance; it’s the threshold requirement for certain markets and customers. However, continuous learning sends a quality signal to clients who are paying attention. Accreditation informs that a lab has met a defined standard at a point in time. But a lab that actively participates in proficiency schemes or tech conferences and proactively updates methods to reflect changes in the industry standards shows that it is interested and invested in current best practices, not just historical compliance.
And for clients making high-stakes decisions based on laboratory data, these are the only signals that matter.
A Practical Closing Thought
Accreditation frameworks provide the structure, and continuous learning provides vitality—Neither works well without the other. A lab that maintains impeccable documentation but doesn’t invest in staying current will eventually find that its procedures have drifted from the latest best practice. Similarly, a lab full of curious, engaged scientists who haven’t institutionalized what they learn will struggle to demonstrate consistent, reproducible performance.
Successful labs tend to treat learning as core to how scientific work gets done. It’s a cultural orientation more than a policy. It starts with what leadership values, not what the training records say.
