ACT501 Chap.4 Auditing Standards and the Shape of an Audit
Auditing Standards and the Shape of an Audit
Two structural things at once
This part of the course settles which body of rules an engagement is performed under, and the order in which an audit happens. Neither is conceptually difficult, and both are easy to lose marks on by being approximately right.
The sequence also happens to be the order of the teaching schedule, so knowing where a topic sits tells you roughly when it is taught and what it assumes.
The Hong Kong family
The umbrella phrase covers the territory's standards on quality management, on auditing, on assurance and on related services, and it names several distinct families rather than one document: the quality management standards; the framework for assurance engagements; the auditing standards themselves; a separate set written for audits of less complex entities; the standards on review engagements; those on assurance engagements; those on investment circular reporting; and those on related services.
Practice notes and guidelines sit alongside them to help apply the engagement standards to particular circumstances and industries.
The lecture also flags the general requirements for sustainability assurance engagements as new for 2026.
Why a separate small-entity standard exists
Applying rules written with large listed groups in mind to a four-person importer produces work that costs more than it is worth to anybody.
The profession answered that with a different standard rather than with informal tolerance, and that is the answer to any question asking whether a small audit may be a lighter version of a large one.
Scale changes which standard applies, never how much of a standard is performed.
Quality management sits above the engagement
The quality management standards apply to the firm rather than to any one audit: how engagements are accepted, how staff are trained and supervised, how work is reviewed, and how the firm monitors itself.
That is why an inspection of an audit firm reviews a sample of engagements alongside an overall evaluation of the firm-wide system, and why a deficiency found in one file is often written up as a system finding.
The distinction matters for the group project, which is built on published inspection reports.
The other two systems, and the fork inside one of them
The mainland system is organised into practice standards covering auditing, firm quality management, review engagements, other assurance engagements and related services, together with a code of professional ethics and practice guidance.
The international layer is the body of auditing standards issued by the board that sets assurance standards internationally. The American arrangement forks on whether the entity is publicly listed: statements on auditing standards govern audits of non-public companies, while auditing standards issued by the public company oversight board govern audits of listed ones.
Government entities fall under the standards of the national audit office and foreign entities under the international standards.
The engagement in order
The lecture maps the audit onto stages: preliminary engagement activities, then planning activities, then understanding the entity, then identifying and assessing risks of material misstatement, then designing and implementing responses to the assessed risks, then completing the audit and forming an opinion and issuing the report.
Two properties of that sequence are examinable and neither is visible in the diagram. Evidence accumulates across the whole engagement rather than in one phase, from preliminary activities through to completion.
And the stages iterate: a risk assessment is revised when a response turns up something unexpected, and a completion review can send the team back for more work.
Naming the right body
The organisations that affect the profession are not all rule writers. A securities regulator supervises markets.
An accounting standards board writes the financial reporting framework the statements are prepared under, not the standards the audit is performed under. A professional institute admits and disciplines members and, in Hong Kong, also issues the engagement standards. Confusing supervision with standard setting is a cheap error to avoid.

The stages of an engagement, and why evidence accumulates across all of them
Three engagements in one week, and the rule family each one sits in
- 3Place each engagement by jurisdiction and by subject matter.
- 3Say what the size of the second entity changes, and what it does not.
- 3Locate the third engagement outside the auditing standards and say what governs it.
Key terms
- Quality Management Standards
- Standards applying to the firm rather than to a single engagement, covering acceptance, training, supervision, review and the firm's monitoring of its own system.
- Practice Note
- Guidance that assists practitioners in applying an engagement standard to particular circumstances or industries, without displacing the standard it interprets.
- Preliminary Engagement Activities
- The stage before planning, in which acceptance and continuance, ethical requirements, competence and the terms of the engagement are settled.
- Risk Response
- The stage at which the auditor designs and implements procedures answering the risks of material misstatement already assessed.
- Issuer
- A company whose securities are publicly listed, which in the American system determines that the listed-company oversight board's standards and inspection regime apply.
Auditing Standards and the Shape of an Audit FAQ
Which standards apply to a small audit?
In Hong Kong an eligible entity may be audited under a separate set of standards written for audits of the financial statements of less complex entities, which exists precisely because applying rules designed for large listed groups to a very small business produces disproportionate work. What size never does is license a reduced version of the main standards.
If the smaller standard applies, it is applied in full; if it does not, the ordinary standards are applied in full.
Who writes the rules for an audit of a company listed in the United States?
The public company oversight board in the United States, whose auditing standards govern audits of listed issuers and whose inspection programme reviews the firms that perform them. Audits of non-listed American companies are governed instead by statements on auditing standards issued by the auditing standards board.
The fork is the listing rather than the size of the company, which is why the group project on inspection reports is working with listed-company standards throughout.
Is evidence only collected during the testing phase?
No, and saying so is a common way to lose a mark in a question about planning. Evidence is gathered across the entire engagement, starting with the acceptance work and ending only at completion. Work done to understand a business produces evidence, and so does the final analytical review.
The stages also iterate rather than running once each: a response that turns up something unexpected sends the team back to revise the risk assessment it was designed from.
Exam move
Take the six stages and write, beside each, the single question it answers and one document it produces. Then check your list against the teaching schedule week by week. Doing that once converts an abstract sequence into a calendar you already have, and it makes the opening clause of a longer answer, naming the stage a problem belongs to, almost automatic.
