Training module
Third-Party Auditing
Navigate accreditation, the certification ecosystem, the audit lifecycle, impartiality boundaries and certification decision interfaces
Do you struggle to understand the unique governance and constraints of audits conducted by certification bodies?
Evaluate supplier evidence under real-world limitations using triangulation and consistency checks
Overview
What this module is about
Audits conducted by certification bodies differ fundamentally from internal audits, operating within a stringent accreditation-driven system that mandates independence and strict separation of audit activity from certification decisions.
This module provides a practical orientation to this complex ecosystem. Participants will learn how accreditation bodies and certification bodies interact, understand the full certification cycle from Stage 1 and Stage 2 through surveillance and recertification, recognise how impartiality is maintained, and clarify how lead auditors interface with review, decision, surveillance, and complaints mechanisms, enabling effective engagement without relying on proprietary procedures.
Audience
Who it is for
Management system implementers and coordinators

Agenda
What is taught
9 parts01What makes third-party audits different
How audits conducted by certification bodies differ from internal audits in purpose and constraints, including independence, impartiality, and the non-consultancy boundary
02Ecosystem and governance landscape
How accreditation bodies, certification bodies, standards, schemes, and sector regulations interact, and how accreditation expectations shape governance, oversight, and consistency in certification activities
03Roles, accountability, and decision separation
How roles are separated across audit, review, and certification decision functions, what auditors may and may not do in client interactions, and where the audit sits within the certification body's controlled process flow
04Competence and impartiality management in certification bodies (CBs)
How CBs manage auditor competence and impartiality at a system level, including qualification logic, assignment constraints, conflict handling, and behavioural expectations
05Audit lifecycle and stage logic
How Stage 1, Stage 2, surveillance, and recertification audits differ in intent, outputs, and limits, and what remains stable across the certification cycle
06Scope, boundaries, and auditability in a certification context
How scope statements, boundaries, exclusions, and multi-site structures are treated in audits conducted by certification bodies, and what “consistent coverage” means
07Impartiality in practice
How auditors recognise and manage common pressure points such as expectations of “helpfulness”, commercial sensitivities, and conflicts, while maintaining professional distance and constructive engagement
08Certification-oriented outputs
How outputs from audits conducted by certification bodies support objective, decision-ready conclusions, with clear separation between evidence, findings, and improvement opportunities, without drifting into consultancy
09Challenges, escalation paths, and complaint governance
How disagreements, complaints, and appeals are positioned at a high level, and how auditors are expected to act when constraints limit access, evidence, or time

Distinguish the intent of Stage 1, Stage 2, surveillance, and recertification at a practical level

Materials
The content and the assessment
Written module
The full content in writing, complete in itself. Videos are recorded for parts of it as an alternative way through, and the written module always carries everything.
Exercises
Graded work on the case organisation's own registers: structured answers checked against the encoded case, written answers scored against a rubric traced to it, with a trainer holding the final word on every assessed item.
On completion
The assessed exercises must be passed before the certificate is issued.
Scheduling
No public run of Third-Party Auditing is scheduled at the moment. Tell us you are interested and we will let you know when the next one opens, or discuss running it in-house.

Case organisation
All modules share one company
Each module enters the company at a particular point in its history and finds it as that history has left it.
Northstar Integrated Services AG is a group headquartered in Zurich, operating in six European countries, with about 1,350 employees at the end of 2025. It provides digital operations platforms and managed operational services to regulated organisations in healthcare, the public sector and industrial services. Founded in 2008 as a field-operations firm serving business customers, it had about twenty-five employees when its first regulated customer, a hospital group, required documented decisions, named accountability and evidence on request. It moved into the platform business in 2016 and in 2024 acquired an operating business in Poland and the Czech Republic, whose legal entity continues inside the group.
Linked registers
Organisation and people, roles, risks, objectives, policies, documents and records, communications, findings, audits and reviews, interested parties, processes
Records, not summaries
The evidence sits in the registers and documents where a real organisation would keep it.
A history
The company has a timeline from 2008, so a structure can be examined before and after it changed.
More than one legal entity
A Swiss parent company and an acquired subsidiary in Poland and the Czech Republic, with customers in several jurisdictions
Why it matters
Judgement develops on material that is incomplete and partly contradictory, as it is in practice. Northstar is built that way on purpose. Because modules enter its history at different points, a governance structure can be seen while it is built, when it is outgrown and when it is rebuilt.
