ISO 17025 training: who needs what, and the competence evidence assessors test

What does ISO/IEC 17025 require for personnel competence?

ISO 17025 training requirements are really competence requirements. The 2017 edition places personnel in clause 6, Resource requirements, as sub-clause 6.2, Personnel, next to facilities, equipment and metrological traceability. The logic is simple: a result is only as reliable as the person who produced it, so the laboratory has to show that each person working on a test or calibration can do it properly.

The practical reading, and the one the hub uses, is competence requirements and authorisations per method. For every role that influences results, the laboratory defines what the person must know and be able to do, then records how each individual met that standard and which activities they are allowed to carry out. Nobody should run a method, review a result or sign a report without a current authorisation that says so.

Two general requirements touch every person as well. Clause 4.1, Impartiality, and clause 4.2, Confidentiality, apply whatever the role, so staff and contractors need to understand the pressures that can bias a result and the duty to protect customer information. Clause 1 makes the standard applicable regardless of the number of personnel, so a two-person laboratory needs the same chain of evidence as a large group, only shorter.

Who needs what training in an ISO/IEC 17025 laboratory

Laboratory management

Clause 5, Structural requirements, expects management to have the authority and resources to run laboratory activities. Managers need to understand what accreditation covers, how impartiality risks arise from ownership and commercial pressure, and how internal audit and management review feed decisions. A focused briefing is usually enough; their evidence is the decisions they record.

Technical staff: analysts and calibration technicians

This is where most of the effort goes. Each person needs method-specific training on every test or calibration they will perform, including sample and item handling, equipment checks, quality control, technical records and what to do when something goes wrong. Understanding why a method was verified or validated and how its uncertainty was evaluated makes them far more convincing when an assessor asks. The detail of those two subjects belongs in method verification and validation under ISO/IEC 17025 and measurement uncertainty under ISO/IEC 17025.

Reviewers and those who authorise reports

People who review results, release reports or calibration certificates, make statements of conformity or give opinions and interpretations carry more risk than those who generate data. They need the decision rule agreed at contract review, the required report content and how amendments to reports are handled. Authorise them separately from the analysts.

Samplers

Where sampling is in your scope, clause 7.3 brings the people who take samples into the competence system, including field staff who never enter the laboratory.

The quality coordinator

Whoever runs the management system needs clauses 4 to 8 in depth, the Option A or Option B choice your laboratory has made, document and record control, corrective action and the management review.

Internal auditors

Auditors need the standard, audit technique and enough technical understanding to follow a result back through its records. The approach is covered in ISO/IEC 17025 internal audit: the technical clauses.

A competence matrix for a testing or calibration laboratory

A matrix connects each role to what it must learn and the evidence that proves it. Treat the table below as a starting point and adjust it to your own methods, equipment and scope of accreditation.

Revisit the matrix whenever a method is added or changed, new equipment arrives, the scope is extended, or a nonconforming work record points to a skills gap.

How to evidence competence: from criteria to authorisation

A convincing competence file for one person and one method usually has five parts, in this order:

1. Criteria. What the role requires in education, training, experience and skill, written before anyone is assessed against it.
2. Training or experience. The course, on-the-job instruction or prior work that closed the gap, traceable to the person.
3. Supervised practice. Runs performed under a competent person, with the results compared against known values, replicates or a reference material.
4. Authorisation. A dated, signed record naming the method or activity the person may now perform unsupervised.
5. Monitoring. Evidence that competence is maintained: quality control results, participation in proficiency testing rounds, observed work and periodic review. How the laboratory plans those rounds is covered in proficiency testing and interlaboratory comparison under ISO/IEC 17025.

During the on-site assessment, technical assessors witness tests or calibrations being performed. They watch the person, ask why each step is done, then compare what they saw with the authorisation list and the training file. When the observed work, the file and the answers agree, competence is demonstrated. The kinds of question to expect are set out in ISO/IEC 17025 assessor questions.

Where competence evidence fails in an accreditation assessment

• Competence assumed, not evidenced. Experienced staff with no written criteria and no authorisation record give the assessor nothing to verify.
• Authorisations out of date. A method revised or a new instrument introduced, but the authorisation list never updated.
• Everyone authorised for everything. A blanket sign-off tells the assessor the laboratory has not thought about individual competence.
• No monitoring. Authorisation granted years ago, with no quality control or proficiency data linked to the person since.
• Reviewers treated like analysts. Nobody separately authorised to release reports or give opinions and interpretations.
• Contractors and samplers left out. They influence results and are sampled like anyone else.

Sterling Academy and internal auditor training

Awareness for the whole workforce and role-based e-learning complement the method-specific training that only your own laboratory can give. Sterling consulting clients benefit from preferential Sterling Academy course access and special pricing through their Sterling consultant, including complimentary awareness training for their people as part of the engagement.

Internal auditor training, as applicable to your standard, is delivered within the consulting engagement. Your Sterling consultant trains your audit team on your own laboratory, so the first audits test the technical clauses as well as the management system.
