ISO/IEC 17025 Gap Analysis Service
ISO 17025 Gap Analysis for Laboratories Pursuing Accreditation
An ISO 17025 gap analysis shows exactly where your laboratory meets ISO/IEC 17025:2017 and where it falls short. Precision ISO reviews your documents, samples your records, interviews your team and witnesses your work. You then receive a clause by clause report, a fix for every gap and a phased roadmap to your accreditation application.
- A rating for every clause area in Sections 4 to 8
- Findings backed by objective evidence from your own records
- Each gap matched to a customizable Precision ISO template
- A phased remediation roadmap with owners and milestones

Why Start Your Accreditation With an ISO 17025 Gap Analysis
Most laboratories underestimate ISO/IEC 17025 for the same four reasons. A gap analysis replaces those assumptions with evidence before you commit budget and staff time.
-
ISO 9001 covers only part of the standard
An ISO 9001 system can carry much of Section 8 under Option B. However, it does not address impartiality, measurement uncertainty, method verification or reporting. Those technical requirements usually hold the largest gaps.
-
A procedure is not a record
Assessors look for evidence that a process runs, not just a document that describes it. We check both. We also flag every procedure that has no completed record behind it.
-
Long lead items set your timeline
Proficiency testing rounds, calibration provider changes and uncertainty budgets all take months. A gap analysis finds them early, so that work starts in week one instead of week twenty.
-
Surprises cost the most at assessment
A finding during your initial assessment brings corrective actions, new evidence and delay. Finding the same gap now gives you time to fix it properly and to show that the fix works.
Not Ready for a Full Review? Start With a Free ISO 17025 Readiness Assessment
Our free ISO 17025 readiness assessment turns the first question into a score. The checklist asks 30 questions across six areas. Each Yes earns 2 points, each Partial earns 1 and each No earns 0. The Excel workbook then totals everything and returns your readiness level.
- 1Business Case and Commitment
- Your business driver, management commitment, planned scope, target date and choice of accreditation body.
- 2People and Project Team
- A project lead, protected time, documented competence, staff authorization and audit experience.
- 3Existing Quality System
- Document control, nonconformity and corrective action, internal audits, management review and complaints.
- 4Methods and Procedures
- Written procedures, published versus in-house methods, verification and validation, uncertainty and reports.
- 5Equipment and Facilities
- Equipment records, accredited calibration, intermediate checks, environmental monitoring and item handling.
- 6Results and Data Integrity
- Proficiency testing, internal quality control, technical records, validated software and impartiality.
| Readiness level | Score | What it means |
|---|---|---|
| Ready to Launch | 80% to 100% | Your lab has a strong foundation. A focused gap analysis confirms the remaining work and sets a realistic timeline. |
| Building Momentum | 55% to 79% | Core systems exist, with clear gaps to close. A gap analysis turns those gaps into a prioritized plan. |
| Foundation Needed | 30% to 54% | Several core systems still need building. Plan a structured implementation project with phases, owners and templates. |
| Early Stage | 0% to 29% | Confirm the business case, secure leadership support and define your scope first. Those decisions shape every later step. |
Three questions act as prerequisites: a clear business driver, management commitment and a project lead. The workbook flags a No on any of them, whatever your total score, because a project without them tends to stall.
What Our ISO 17025 Gap Analysis Covers
Our ISO 17025 gap analysis assesses your laboratory against every requirement of ISO/IEC 17025:2017. If you hold ISO 9001 certification, we also assess the supporting processes your lab will rely on under Option B. The summaries below paraphrase the standard, so work from your own controlled copy.
Sections 4 to 6
- Section 4, general requirements
- Impartiality, including how you identify and manage risks to it, and confidentiality of customer information.
- Section 5, structural requirements
- Legal responsibility, the documented range of laboratory activities, and defined roles, authority and reporting lines.
- Section 6, resource requirements
- Personnel competence and authorization, facilities and environmental conditions, equipment, metrological traceability and external providers.
Sections 7 and 8
- Section 7, process requirements
- Contract review, method selection and verification, sampling, item handling, technical records, measurement uncertainty, validity of results, reporting, complaints, nonconforming work and data control.
- Section 8, management system requirements
- Your choice of Option A or Option B, documentation, document and record control, risks and opportunities, improvement, corrective action, internal audits and management review.
How the Gap Analysis Works
Every ISO 17025 gap analysis follows the same five steps. We size the effort on the first call, so you know the scope and the deliverables before any work starts.
Scoping call
We confirm your planned scope, methods, sites and deadline. You then receive a proposal and a document request list.
Document review
We review your quality manual, procedures, work instructions and forms against each clause before the visit.
Assessment visit
We sample records, interview staff and witness tests or calibrations. Document review can run remotely.
Written report
You receive ratings, evidence, findings, a document crosswalk and a phased roadmap.
Debrief and plan
We walk your team through the findings and agree on the order of work, owners and target dates.
Inside Your ISO 17025 Gap Analysis Report
Every report follows the same structure, so your team can act on it the day it arrives. The example report shows the format. We built it for a fictional ISO 9001 certified manufacturer whose in-house lab is pursuing accreditation.
- Executive summary
- Overall readiness, the Major findings that need priority action and any immediate risk to results already reported.
- Clause by clause results
- A rating and a finding reference for every clause area, summarized by section of the standard.
- Document gap analysis
- A crosswalk of your documents against the Precision ISO library, marked Adequate, Revise or Create.
- Detailed findings
- The requirement in plain language, the objective evidence, the gap, its impact and the recommended actions.
- Strengths and observations
- What already works well, so your team protects it during remediation.
- Remediation roadmap
- A phased plan with timing, owners and a readiness checklist to complete before you apply.
| Rating | What it means |
|---|---|
| Conforming | The requirement is addressed, implemented and supported by objective evidence. |
| Minor | The requirement is partly addressed, or an isolated lapse exists that does not by itself call results into question. |
| Major | The requirement is not addressed, or a systemic gap could affect results or prevent accreditation. |
| Observation | The area conforms today, but an improvement would strengthen it before assessment. |
| Not applicable | The requirement does not apply to your current activities, and the report records why. |
Gaps We Find Most Often in ISO 17025 Readiness Assessments
Every laboratory differs, yet the same gaps appear again and again. All six of these appear in the example report. They also mirror what we see most often in practice.
Impartiality in an in-house lab
The lab reports to the manager who owns production output. No impartiality risk assessment or retest criteria exist.
Traceability through unaccredited providers
A provider without accreditation calibrates critical equipment and reports no uncertainty, so the lab cannot show traceability.
No evaluated measurement uncertainty
Calibrations rely on a 4:1 accuracy ratio instead of an uncertainty budget. The ratio compares tolerances. It does not quantify uncertainty.
Methods that were never verified
Published methods have run for years with no verification record. Meanwhile, in-house procedures carry no validation at all.
Nonconforming work stops at the product
The NCR system works for product. Yet when equipment fails, nobody evaluates the results the lab already reported.
Internal audits that skip ISO 17025
The ISO 9001 audit program treats the lab as a measuring resource. As a result, nobody audits it against ISO/IEC 17025.

A free 30 minute call is enough to scope your ISO 17025 gap analysis and answer your first questions.
Who Needs an ISO 17025 Gap Analysis
An ISO 17025 gap analysis fits three situations. Each one benefits from an independent view before the work begins.
Labs seeking first accreditation
Testing and calibration laboratories that need a clear plan, a realistic timeline and a list of the documents to write.
Manufacturers adding a lab
Organizations with ISO 9001 certification and an in-house lab. They want to reuse their system under Option B and focus on the technical gaps.
Accredited labs facing change
Laboratories preparing for reassessment, expanding their scope, changing accreditation bodies or recovering from a difficult assessment.
Readiness Checklist, Gap Analysis or Internal Audit?
These three tools answer different questions. Use the readiness checklist to decide whether to start, the gap analysis to plan the work and internal audits to keep the system honest once it runs.
| Free readiness checklist | ISO 17025 gap analysis | Internal audit | |
|---|---|---|---|
| Who performs it | Your own team | An experienced Precision ISO auditor | Trained auditors independent of the work |
| Depth | 30 questions in six areas | Every clause, with records sampled and work witnessed | Every clause over a planned program |
| Basis | Your own judgment | Objective evidence from documents, records, interviews and observation | Objective evidence |
| What you get | Section scores and a readiness level | A report with findings, a document crosswalk and a roadmap | An audit report and corrective actions |
| Best time | Before you budget the project | Before implementation, reassessment or a scope change | Once your system runs, at planned intervals |
Who Performs Your Gap Analysis
Led by Dusty Williams
Dusty founded Precision ISO and leads each ISO 17025 gap analysis personally. He holds a bachelor's degree in chemistry. He also brings five years of analytical chemistry work and more than ten years in measurement uncertainty, metrology and laboratory accreditation.
He has guided laboratories through accreditation and built uncertainty budgets across a wide range of measurement disciplines. That technical depth matters most in Section 7, where the hardest gaps usually sit.
Faster evidence review, human judgment
For large document sets, our AI internal audit tool speeds up the search for evidence across your quality system. It cites the document and page for each clause.
A qualified auditor still reviews and approves every finding. The tool shortens the slow part. It never replaces the auditor's judgment.
ISO 17025 Gap Analysis FAQ
How long does an ISO 17025 gap analysis take?
It depends on your scope, the number of disciplines and sites, and how much documentation already exists. We confirm the timeline on the scoping call. Most of the effort goes into the document review and the assessment visit, and the written report follows soon after.
Can you perform the gap analysis remotely?
Yes, for most of it. We review documents and records remotely and interview staff by video. Witnessing tests and calibrations works best in person, so we usually recommend at least a short site visit.
Does a gap analysis guarantee accreditation?
No. A gap analysis shows where you stand and what to fix. Your accreditation body makes the accreditation decision. The outcome depends on how your laboratory implements, operates and maintains its management system.
Do we need ISO 9001 certification first?
No. ISO/IEC 17025 stands on its own under Option A. If you already hold ISO 9001 certification, Option B lets your existing system cover much of Section 8. The gap analysis shows exactly how much of it carries over.
How does the readiness checklist differ from a gap analysis?
The checklist is a self assessment. Your team answers 30 questions and gets a readiness level in minutes. An ISO 17025 gap analysis is an independent review of your documents, records and practices against every clause, with objective evidence behind each finding.
Will you tell us which documents to write?
Yes. The report includes a document crosswalk that matches each gap to a Precision ISO library template, marked Adequate, Revise or Create. You can keep your own document numbering.
Can Precision ISO help us close the gaps?
Yes. Many clients continue into implementation support, uncertainty budgets, internal auditor training or a readiness review before application. You can also take the report and close the gaps with your own team.
Do you offer ISO 9001 gap analysis too?
Yes. We also assess quality management systems against ISO 9001:2015 for certification readiness. Mention it on your consultation call, and we will scope it alongside your ISO/IEC 17025 review or on its own.
Is the readiness checklist really free?
Yes. Fill in the short form at the top of this page and we email you the Excel workbook. Use it with your team, share the results with leadership or bring them to your consultation.

A gap analysis is a sample based review of the evidence available at the time. It does not constitute legal, regulatory or accreditation advice, and it does not guarantee that an accreditation body will grant accreditation. Clause summaries paraphrase ISO/IEC 17025:2017 and do not reproduce the standard. Always work from your own controlled copy. The example report describes a fictional organization. The readiness checklist is a self assessment for planning purposes only.
