CFA Standard I(E) Competence Explained

Updated 8 October 2026 · Fact-checked

Standard I(E) Competence requires you to be competent in the work you do and to maintain and improve your professional skills and knowledge. In exam cases, check whether the member has the skills for the task, take on only work they can do well, and keep learning. If not, the member should decline, get help or train.

Understand Standard I(E) Competence

Standard I(E) Competence sits under Professionalism. It requires members to act with and maintain the competence needed for their work, and to maintain and improve their professional skills and knowledge.

The standard has two parts. First, you must act with and maintain the competence needed to do your job. Second, you must maintain and improve your professional skills and knowledge. In plain words: do not take on work you cannot do well, and keep your skills current.

Competence is not perfection. The standard does not say you must know everything or never make an error. It says you must have the knowledge, skill and ability for the task, and must act to close gaps. That can mean training, supervision, hiring an expert, or declining the work.

Think of a portfolio manager who is asked to manage a client's private equity or crypto exposure with no experience in it. The manager can study first, bring in a qualified specialist, or decline. What the manager should not do is carry on and hope the client does not notice.

On the exam, name the main standard that the facts point to. Add a second standard, such as V(A) or III(C), only if the facts clearly support it.

Key rules to remember

Standard I(E) core duty
Competence = act with and maintain the competence needed for your work
Applies to the tasks you accept and the advice you give. Do not take on work beyond your skills without a fix.
Continuing development duty
Maintain and improve professional skills and knowledge
An ongoing duty. A one-time qualification does not satisfy it by itself.
Acceptable responses to a skills gap
Train, get supervision or expert help, or decline the work
These are the compliant options. Carrying on unprepared is the breach.

How to solve Standard I(E) Competence questions

Use this method for any Standard I(E) question, whether it is an item set or an essay set.

  1. 1Read the facts and identify the task the member has taken on, such as a new asset class, a new client type or a new role.
  2. 2Ask whether the member has the knowledge, skill and ability for that task right now.
  3. 3If there is a gap, check what the member did about it: trained, sought help, supervised, or declined. Or did nothing?
  4. 4Check whether the member is keeping skills current, for example through study, training or staying aware of changes.
  5. 5Decide whether there is a violation. A gap handled properly is not a violation. A gap ignored is.
  6. 6Name the standard: I(E) Competence. Add V(A) or III(C) only if the facts show poor analysis or unsuitable advice.
  7. 7State the recommended action in few words, using the command word given. Keep it to the number of answers asked for.

Quickest way: Gap, action, outcome check

When to use it: Use it for multiple-choice questions in an item set when you have under two minutes per question.

  1. Find the task and the member's relevant skill. Mark whether a gap exists.
  2. Look for what the member did about the gap.
  3. Pick the option that has the member training, getting qualified help or declining. Reject options that continue unprepared or hide the gap.
  4. If two options look right, choose the one that protects the client first.

Common mistakes in Standard I(E) Competence

  • Thinking the standard requires expertise in everything

    The word competence sounds absolute.

    Fix: Remember the standard asks for competence in the work you do. Admitting a gap and fixing it is compliant.

  • Saying any skills gap is a violation

    Students focus on the gap and skip what the member did next.

    Fix: Always check the response. Training, expert help or declining is acceptable. Ignoring the gap is the breach.

  • Treating a one-time qualification as enough

    Holding a charter feels like proof of ongoing competence.

    Fix: The standard includes a continuing duty to maintain and improve skills and knowledge.

  • Citing V(A) or III(C) instead of I(E) automatically

    Students link any weak advice to diligence or suitability without checking what the facts show.

    Fix: Cite I(E) when the issue is the member's ability to do the work. Name the main standard the facts point to, and add V(A) or III(C) only if the facts support them.

  • Assuming relying on others is a violation

    Students think the member must personally do everything.

    Fix: Using qualified specialists or supervision is an acceptable way to close a gap, provided the member still meets their own duties.

  • Giving long essay answers with several actions

    Candidates want to cover every possibility.

    Fix: Answer the command word and give only the number of responses requested. Extra answers are not evaluated.

Worked examples

Example 1

A portfolio manager at a wealth firm has only managed listed equities. A client asks her to add a large allocation to private credit. She has no experience in it and does not tell the client. She accepts and invests using a brief internet search. Identify the standard violated and state what she should have done.

Show the solution
  1. Task: managing a private credit allocation, a new asset class for her.
  2. Gap: she lacks relevant knowledge and experience.
  3. Response: she did not train, seek help or decline.
  4. Primary standard: she took on work without the needed competence, so Standard I(E) is violated. This is the main answer.
  5. Other standards: she did not tell the client about her limits and relied on a brief internet search. That may also implicate V(A) Diligence and Reasonable Basis and III(C) Suitability. Add these only as secondary points.
  6. Correct action: she should have declined, studied the asset class first, or involved a qualified specialist, and been open with the client about the limits of her experience.

Answer: The primary violation is Standard I(E) Competence. Investing on a brief internet search and not disclosing her limits may also implicate V(A) Diligence and III(C) Suitability. She should have acquired the needed skills, used qualified specialist help, or declined the mandate.

Example 2

A CFA charterholder has worked in fixed income for fifteen years. He has not attended training or reviewed new developments since qualifying, and markets and products in his area have changed a lot. His firm is satisfied with his results. Which is the most accurate statement under Standard I(E)? A. He complies because his firm is satisfied. B. He complies because he has been qualified for fifteen years. C. He may not be complying because he has not maintained and improved his skills and knowledge. D. He violates only if a client suffers a loss.

Show the solution
  1. Standard I(E) includes a continuing duty to maintain and improve skills and knowledge.
  2. Option A: employer satisfaction does not replace the duty. Reject.
  3. Option B: past qualification does not show current competence. Reject.
  4. Option D: the standard does not depend on a client loss. Reject.
  5. Option C fits the continuing duty and is worded cautiously, since the facts show no development activity.

Answer: C. He may not be complying because he has not maintained and improved his skills and knowledge.

Exam tips

  • Look for facts about a new asset class, new role, new technology or new client type. These signal Standard I(E).
  • Check the member's response to the gap. The correct answer usually involves training, qualified help or declining.
  • Do not default to V(A) or III(C). Name I(E) when competence is the core issue.
  • In essay sets, follow the command word and keep your answer concise but complete, covering the violation and the fix. Only the number of responses asked for is evaluated, in the order given, so put your best answers first.
  • Know the exact two parts of the standard: act with and maintain competence, and maintain and improve skills and knowledge. Apply them to the facts given.

You must act with and maintain the competence your work needs. You must also keep improving your professional skills and knowledge. If you lack a skill for a task, close the gap or decline the task.
