Professional Ethics and Personal Conduct in ACCA Business and Technology

Updated 11 October 2026 · Fact-checked

Professional ethics in ACCA means following five fundamental principles: integrity, objectivity, professional competence and due care, confidentiality, and professional behaviour. To answer exam questions, identify the situation, match it to the principle breached, and choose the response that keeps you honest, unbiased, competent, discreet and lawful.

Understand Professional Ethics and Personal Conduct

An accountant is trusted because others rely on their work. Investors, lenders, employers and the public cannot check everything themselves. Ethics is what makes that trust reasonable. The ACCA Code of Ethics and Conduct sets out five fundamental principles that every ACCA member and student is expected to follow.

The five principles are:

  • Integrity: being straightforward and honest in all professional and business dealings.
  • Objectivity: not letting bias, conflict of interest or the influence of others override your professional judgement.
  • Professional competence and due care: keeping your knowledge and skills up to date and acting diligently in line with technical and professional standards.
  • Confidentiality: respecting the confidentiality of information gained through work, and not disclosing it or using it for personal gain without proper authority, unless there is a legal or professional right or duty to disclose.
  • Professional behaviour: complying with relevant laws and regulations and avoiding any action that discredits the profession.

The difference between integrity and objectivity is a favourite search and a favourite exam trap. Integrity is about truthfulness: you do not lie, mislead or hide facts. Objectivity is about independence of judgement: you do not let a relationship, a favour, pressure or self-interest bend your decision. You can be honest and still biased. For example, you might truthfully report a friend's figures but go easy on them because they are a friend. That is an objectivity problem.

Personal conduct links ethics to personal effectiveness. Being punctual, prepared, honest about mistakes, respectful of colleagues and careful with information all build a professional reputation. Poor conduct damages your credibility, your team and your employer.

The ACCA Code takes a principles-based approach. It does not list a rule for every case. It expects you to use judgement, identify threats to the principles and apply safeguards. In BT objective tests you are usually asked to recognise which principle applies or which action is appropriate.

Key formulas to remember

Five fundamental principles
Integrity + Objectivity + Professional competence and due care + Confidentiality + Professional behaviour
Memory aid: I-O-P-C-P. Be able to define each in one line and match it to a scenario.
Integrity test
Integrity = honest and straightforward; no misleading or false information
Look for lying, hiding facts, or being associated with misleading reports.
Objectivity test
Objectivity = no bias, conflict of interest or undue influence on judgement
Look for gifts, family or friendship ties, pressure from a boss or a financial interest.
Competence and due care test
Competence and due care = up-to-date skills + diligent work to standards
Look for taking on work you cannot do, or careless work, or skipped CPD.
Confidentiality test
Confidentiality = no disclosure or personal use without authority, unless a legal or professional right or duty exists
Disclosure can be allowed when the law requires it or when there is a professional duty or right to disclose.
Professional behaviour test
Professional behaviour = comply with laws and regulations + avoid discrediting the profession
Look for illegal acts, exaggerated claims or conduct that harms the profession's reputation.

How to solve Professional Ethics and Personal Conduct questions

Use this method for any scenario question on ethics and personal conduct, whether multiple choice, multiple response or a short multi-task part.

  1. 1Read the last line first so you know whether you must name a principle, pick an action or select several statements.
  2. 2Identify the key facts: who is involved, what was done, and who might be affected.
  3. 3Ask which behaviour is wrong or at risk: dishonesty (integrity), bias or pressure (objectivity), lack of skill or care (competence), sharing information (confidentiality), or breaking rules or harming reputation (professional behaviour).
  4. 4If more than one principle seems to fit, choose the one the facts point to most directly, as in the main wording of the scenario.
  5. 5For action questions, prefer responses that stay within the principles: refuse to mislead, declare the conflict, get training or help, protect information, follow the law.
  6. 6Reject extreme options such as ignoring the issue entirely or immediately going public, unless the law or a duty clearly requires it.
  7. 7Check your answer against the question wording, especially words like 'most', 'first' and 'not'.

Quickest way: Keyword matching for principle questions

When to use it: Use when you have about a minute for a two-mark objective test question that asks which principle applies.

  1. Scan the scenario for a trigger word.
  2. Lying, misleading, false claims: integrity.
  3. Gift, friendship, family, pressure, financial interest: objectivity.
  4. Lacks knowledge, careless, out of date: professional competence and due care.
  5. Tells others, uses private information: confidentiality.
  6. Breaks law or damages image of profession: professional behaviour.
  7. Eliminate options that name a principle not touched by the facts, then choose from the rest.

Common mistakes in Professional Ethics and Personal Conduct

  • Treating integrity and objectivity as the same thing.

    Both sound like 'being fair and honest', so students blur them.

    Fix: Remember integrity is honesty and not misleading; objectivity is freedom from bias and influence. Ask whether the issue is a lie or a biased judgement.

  • Saying confidentiality means information can never be disclosed.

    The principle is often learned as 'keep secrets' without its exceptions.

    Fix: State that disclosure is allowed with proper authority, or where there is a legal or professional right or duty to disclose.

  • Confusing professional competence with professional behaviour.

    Both contain the word 'professional'.

    Fix: Competence is skill and care in the work. Behaviour is following laws and not harming the profession's reputation.

  • Choosing the most dramatic action, such as reporting to the authorities at once.

    Students think strict means correct.

    Fix: Choose the proportionate step first, such as raising it with the appropriate person in the organisation, unless the facts say the law requires immediate reporting.

  • Assuming ethics only applies to qualified accountants at work.

    The Code is seen as an audit or practice topic.

    Fix: Remember it applies to ACCA members and students, and to everyday conduct such as honesty with colleagues and care with information.

  • Naming a principle without linking it to the facts.

    Students recall definitions but skip application.

    Fix: Always say what happened in the scenario and why that breaches the named principle.

Worked examples

Example 1

A junior accountant is preparing a report on a supplier. The supplier's owner is her cousin. She marks the supplier as low risk without completing the usual checks. Which fundamental principle is most directly threatened? Options: A Integrity; B Objectivity; C Confidentiality; D Professional behaviour.

Show the solution
  1. Identify the facts: a family relationship with the supplier and a lighter review because of it.
  2. Ask what is wrong: she is not necessarily lying, but her judgement is influenced by a personal relationship.
  3. Match to the principle: bias or conflict of interest points to objectivity.
  4. Check the others: there is no disclosure of information (not confidentiality), no clear law broken (not professional behaviour), and no stated deliberate deception (integrity is less direct).

Answer: B Objectivity. The family tie threatens her unbiased judgement, so she should declare the relationship and have the review done properly or by someone else.

Example 2

An accountant at a company is asked by a friend at a competitor how the company's next-year pricing plans look. The accountant knows the plans from confidential board papers. He is thinking of sharing a rough idea. Explain what he should do and which principle applies.

Show the solution
  1. Identify the information: pricing plans from confidential board papers, learned through work.
  2. Name the principle: confidentiality, which forbids disclosure without proper authority.
  3. Check for exceptions: there is no legal or professional duty or right to disclose here, and no authority from the company.
  4. State the action: he must not share the information, even roughly, and should politely decline.
  5. Add the link to conduct: sharing could also discredit him and the profession, which touches professional behaviour.

Answer: He should refuse to disclose anything. This is a confidentiality issue, because the information was gained through work and there is no authority or legal or professional duty to disclose it.

Exam tips

  • Learn the five principles by heart with a one-line definition each, as many objective test questions are simply matching.
  • For multiple response questions, select exactly the stated number and make sure each choice is directly supported by the facts.
  • Read for the trigger: gift or relationship usually means objectivity; lying or misleading usually means integrity.
  • Do not overstate the rules. Confidentiality has exceptions, so avoid answers that say 'never' unless the wording clearly demands it.
  • Link this topic to threats, safeguards and whistleblowing, as scenarios often combine them.

Professional Ethics and Personal Conduct: frequently asked questions

What are the ACCA fundamental ethical principles?

There are five: integrity, objectivity, professional competence and due care, confidentiality, and professional behaviour. They apply to ACCA members and students. You should be able to define each and recognise it in a scenario.

What is the difference between integrity and objectivity?

Integrity means being honest and straightforward and not being party to misleading information. Objectivity means your judgement is not distorted by bias, conflicts of interest or pressure from others. A person can be truthful but still biased.

Can an accountant ever disclose confidential information?

Yes, in limited cases. Disclosure is allowed with proper authority, or where there is a legal or professional right or duty to disclose. Otherwise the information must stay confidential and must not be used for personal gain.

How is this topic tested in BT?

It appears in computer-based objective test questions, usually as short scenarios asking which principle is affected or what action is appropriate. It can also appear within the multi-task questions in Section B.
