Training module
Audit Principles
Apply evidence-based audit reasoning, materiality-focused prioritisation and structured audit test planning
Are your audits lacking focus, leading to inconsistent findings and wasted effort?
Develop a robust audit mindset and master the principles of evidence and judgement to conduct highly effective audits from the outset.
Overview
What this module is about
Many audits become mere checklist exercises, resulting in unfocused effort and findings that are difficult to substantiate.
This training module addresses this challenge by equipping auditors with the core skills to think critically about evidence, sufficiency, professional judgement, and principled conduct. Participants will learn to translate audit criteria and materiality into a clear, defensible audit approach and test plan, while keeping impartiality, confidentiality, and professional discipline visible in how audit conclusions are formed.
Audience
Who it is for
Management system implementers and coordinators
Executives and department heads accountable for management system performance
Those responsible for processes, policies, assets, risks and controls
Auditors seeking insight into management-side practice, not audit technique
Consultants working on management system design, governance or improvement
Decision supportIs this module for you?
It is a good fit if you…
want to focus audits using criteria, significance, and criticality instead of checklist coverage alone.
need to decide where deeper testing matters most and where proportionate coverage is enough.
want to use sampling deliberately rather than mechanically.
need to build audit plans and test plans that connect criteria, evidence, and lines of inquiry.
want to strengthen audit judgement, impartiality, and defensible findings from source to conclusion.
It may not be the best fit if you…
already plan audits with clear, judgement-led sampling and test logic.
expect fixed sampling rules or checklist-based audit test plans.
are primarily looking for interviewing, reporting, or audit writing skills.
want shortcuts or heuristics without revisiting audit judgement fundamentals.
What to bring
This module assumes participants have basic familiarity with management systems and organisational processes, and are able to read and interpret audit criteria (policies, procedures, requirements, obligations).
Helpful background includes:
General understanding of process-based working and documented system information
Exposure to internal audit purpose and governance (helpful but not required)
Agenda
What is taught
6 parts01What audit judgement means in practice
How audit judgement balances evidence, sufficiency, defensibility, and principled conduct, and where common failure modes such as checklist drift, bias, and scope creep undermine audit quality
02Criteria and materiality as the audit focus mechanism
How to move from criteria to what actually matters using a materiality or significance lens, and define audit depth without turning the module into a risk assessment course
03Evidence logic: what would count, and why
How to reason about evidence sources, triangulation, and contradictions, and determine what constitutes sufficient and appropriate evidence in real audits
04Sampling intent and coverage decisions
How to use sampling as a judgement tool rather than a statistical exercise, and document rationale and limits in a proportionate way
05Audit planning at audit level
How to translate audit focus into a concrete audit approach covering structure, sequencing, and constraints, and distinguish what belongs in the audit plan versus elsewhere
06Designing audit test plans
How to design audit trails or lines of inquiry by mapping criteria to questions, evidence, and sampling intent, and apply quality checks for coherence, completeness, and practical usability
Outcomes
Learning outcomes
01
Apply audit judgement to determine sufficient and defensible evidence requirements while maintaining impartiality and professional discipline
02
Utilise criteria and materiality to define audit focus and depth, moving beyond checklist reliance
03
Design audit test plans that effectively link criteria to inquiries, planned evidence, and sampling intent
Select and justify evidence sources and triangulation strategies for diverse audit scenarios
Define sampling intent and document a clear rationale appropriate to audit objectives
Recognise and rectify common preparation shortcomings that lead to weak findings
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 Audit Principles 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.
