ExploreAbout this exam
The ICAEW ACA is the chartered accountancy qualification offered by the Institute of Chartered Accountants in England and Wales, described on ICAEW.com as "one of the most advanced learning and professional development programmes available" and valued "around the world in business, practice and the public sector". Sustainability and Ethics is one of the ACA's specialist learning areas: ICAEW's own subject structure on ICAEW.com presents "Sustainability and climate change" and "Trust & Ethics" as two distinct areas of guidance and resources, and the ACA training pages list "Ethics and professional scepticism" as a named element of student training. This page is an independent study resource for candidates preparing in those two areas. It is not an official ICAEW product and makes no claim of affiliation, endorsement or accreditation. The two areas are examined together because they share a mindset rather than a body of arithmetic: recognising a judgement problem, identifying the stakeholders and standards engaged, and reaching a defensible conclusion you can explain. Preparation should combine ICAEW's published Code of Ethics and its supporting guidance with ICAEW's sustainability and climate change resources, then be tested through scenario-based practice. Candidates should confirm current syllabus, exam format, sittings, fees and results arrangements directly with ICAEW before booking, because ICAEW publishes and revises those details itself and they are not reproduced here.
What you'll study
About ICAEW ACA Sustainability and Ethics preparation
Is this an official ICAEW exam page?
No. It is an independent study resource written for candidates searching for this exam. It is not produced, endorsed or accredited by ICAEW and does not claim any affiliation. Always treat ICAEW.com as the authoritative source for syllabus content, exam administration, fees and regulations, and verify anything here against it before you rely on it.
What does the exam cover?
Two areas. Sustainability and climate change covers how sustainability is defined and how it connects to accountability, climate reporting and modern slavery. Trust and Ethics covers the ICAEW Code of Ethics, help with ethical problems, economic crime, anti-money laundering, data protection and business law. Expect scenario-based judgement questions rather than pure computation.
How should I sequence my study?
Build ethics first, because the Code of Ethics framework gives you the vocabulary for everything else. Work through threats, safeguards and the conceptual approach until you can apply them without prompting. Then move to sustainability and climate change, where the challenge is linking reporting and accountability concepts to a scenario. Finish with mixed practice so you switch between the two mindsets under time pressure.
How difficult is it?
Difficulty is not the main obstacle; precision is. Most content is understandable on a first read, but questions test whether you can identify the specific threat or issue and justify a conclusion. Candidates who memorise lists without practising application tend to underperform. ICAEW describes the ACA overall as an advanced learning and professional development programme, so expect professional-level reasoning.
Where do I find the exam format, dates and fees?
Only on ICAEW.com. ICAEW publishes exam booking, exam resources, dates and deadlines, credit for prior learning, results and its CPD and training regulations through its student pages. This page deliberately does not state a format, duration, question count, pass mark, fee or retake policy, because those details change and must be confirmed directly with ICAEW.
What is the most common failure mode?
Answering the question you expected rather than the one asked. Candidates spot a familiar topic, such as a conflict of interest or a climate disclosure, and write everything they know about it instead of addressing the specific facts and the specific requirement. Read the scenario twice, identify exactly who is affected and what decision is needed, then answer only that.
How much does professional scepticism matter?
Considerably. ICAEW lists ethics and professional scepticism as a specialised learning area within ACA training and produces training films focused on professional scepticism, ethics and everyday business challenges. Treat scepticism as an examinable behaviour: question the evidence, notice what is missing from the scenario, and say so explicitly rather than accepting assertions at face value.
Are there official resources I can use?
Yes, on ICAEW.com. ICAEW publishes its Code of Ethics and supporting information under Trust & Ethics, together with guidance on ethical problems, anti-money laundering, economic crime, data protection and business law. Under Sustainability and climate change it publishes a climate hub, material on the Sustainable Development Goals, accountability and modern slavery. All ACA learning materials are digital only, accessed via BibliU.
Does this count towards CPD?
ICAEW states that Continuing Professional Development is an integral part of being a successful ICAEW Chartered Accountant and provides a CPD record, guidance and FAQs. Whether any particular study activity counts depends on the CPD requirements that apply to you, so check ICAEW's CPD guidance and record activity there rather than assuming private study automatically qualifies.
