What this subject is really about
Assurance builds on the core Audit and Risk subject, which is its prerequisite. Where the audit looks at historical financial statements, this elective covers the wider family of engagements a chartered accountant is asked to perform: agreed-upon procedures, assurance over non-financial information, sustainability assurance, compliance work and reports on controls.
It is a judgement subject. The marks reward recommending the right engagement, applying the relevant standard to the facts, and holding professional scepticism throughout. The notes are built for that: the framework and the wording first, then how to use them on a case.

The standards you'll use
Almost every question turns on choosing the right engagement, then the standard that governs it. You apply one set throughout, either International, Australian or New Zealand.
Assurance engagements other than audits or reviews of historical financial information. The backbone standard for the subject.
Agreed-upon procedures engagements. You report factual findings, not an assurance conclusion.
Performance engagements, on economy, efficiency and effectiveness.
Sustainability assurance and the phasing of limited and reasonable assurance over climate disclosures in Australia.
Compliance engagements, providing assurance against a set of requirements.
Controls at a service organisation, and assurance on controls more broadly.
These references reflect the subject as at the start of 2026. Standards change, so confirm the current set against your subject materials before you rely on it, and apply one framework consistently.
How it's assessed
This subject has no invigilated exam. It is assessed by one submission in two parts, a written response and a recorded presentation, submitted together in the final week.
Written submission
Apply the relevant standards and practical skills to a case study, documenting how you would plan, perform and complete the engagements.
Recorded presentation
A short video responding to an assurance scenario, marked on clarity and judgement.
Case based
Because the marks are in your analysis and delivery, the pack is built around worked cases, not a timed paper.
The traps worth knowing before the assessment
These are the mistakes markers see most often in assurance answers. The judgement is what earns the marks.
Choosing the wrong engagement before you write a word. Match the subject matter and the level of assurance the client needs to the right engagement first.
Confusing agreed-upon procedures with assurance. Agreed-upon procedures report factual findings and give no conclusion, so do not write one in.
Blurring reasonable and limited assurance. Reasonable assurance is expressed as a positive opinion, limited assurance in the negative form, and the difference reflects the evidence gathered.
Scattering standard references through an answer. Reference the governing standard once, correctly, rather than naming several.
Treating sustainability assurance as optional reading. It is a full chapter and a live commercial skill, so give it real weight.
Losing professional scepticism. An explanation that does not sit with the evidence is the moment to dig in, not to move on.
The kind of question you'll face
A short scenario of the kind the subject uses, so you can see what assurance judgement looks like on paper.
Banksia Foods Ltd asks your firm to provide assurance over the greenhouse gas figures in its first voluntary sustainability report, ahead of the year it will be required to report. The board wants credibility with lenders but is wary of cost in year one. What engagement do you recommend, and at what level of assurance?
Reading the client's real need, choosing between reasonable and limited assurance under ISAE 3000 and the sustainability assurance standards, and scoping the engagement so the report says what the client can defend.
The worked case sets out the engagement choice, the standard, the level of assurance and the scope, with the reasoning laid out so you can see how a strong answer is built.
How to study it around a full-time job
The subject runs over a 7-week study period, six teaching weeks then the assessment. Here is a plan that fits it around work.
Framework and AUP
The assurance concepts and agreed-upon procedures. Get the difference between an assurance conclusion and factual findings solid, because it underlies everything.
ISAE 3000 and sustainability
Assurance engagements beyond the audit, and sustainability assurance. This is where the current commercial work sits.
Compliance and controls
Compliance engagements and controls at a service organisation. Practise scoping each from a short brief.
Build the decision map
Draft a one-page engagement-type map, then run past cases through it until the choice is automatic.
Write and record
Draft the written response, then rehearse the presentation until it is clear and short. Delivery carries real marks.

Plain English, assessment ready
The whole subject rewritten to be read fast. Here is the assurance-level distinction, as it appears in the notes.
Reasonable and limited assurance
Reasonable assurance is a high, but not absolute, level of assurance, expressed as a positive opinion. Limited assurance is lower and expressed in the negative form, that nothing has come to the practitioner's attention to suggest a material misstatement. The difference reflects the amount of evidence gathered.
The engagement map on one page
- Factual findings, no conclusion -> agreed-upon procedures (ASRS 4400)
- Assurance over other information -> ISAE 3000 / ASAE 3000
- Assurance against requirements -> compliance (ASAE 3100)
- Controls at a service organisation -> ASAE 3402
- Reasonable assurance is a positive opinion; limited assurance is the negative form
Cases marked like the real thing
Scenario-led cases that mirror the written submission, each with a model response to learn from.
Common questions
How is Assurance different from Audit and Risk?
Audit and Risk is the audit of historical financial statements. Assurance covers everything else a firm is asked to sign: agreed-upon procedures, assurance over non-financial information, sustainability assurance, compliance and controls. It assumes the audit knowledge and builds sideways from it.
Is there an exam?
No. The subject is assessed by a single submission with a written part and a recorded presentation, submitted together in the final week. There is no invigilated exam.
What do I need before I start?
Audit and Risk is the prerequisite. The subject assumes you are comfortable with assurance concepts and the ethical principles that apply to professional accountants.
Which standards should I use?
You pick one set, International, Australian or New Zealand, and apply it throughout. Our notes are written so the reasoning holds whichever set you choose.
Does it cover sustainability assurance?
Yes. A full chapter covers sustainability assurance, which is one of the fastest growing areas of assurance work in Australia as mandatory climate reporting phases in.
