CFA Level 1 Ethics: Weightage, Syllabus and the Ethics Adjustment Explained

Last Updated: September 2026

The CFA level 1 ethics topic tests more than your ability to remember professional standards. Questions require you to apply the Code and Standards to situations involving clients, employers, colleagues and investment decisions.

Ethics also has a specific role in the final result. When a candidate's overall score is close to the Minimum Passing Score (MPS), Ethics performance may affect the final pass or fail outcome. However, Ethics does not have a separate passing score. Your overall performance is evaluated against the MPS.

CFA Level 1 Ethics Weightage: 2026 vs 2027

The CFA ethical and professional standards weightage changes with the curriculum year. Your exam window determines which figure applies.

November 2026 is the last Level I exam window using the 2026 curriculum. Candidates sitting from February 2027 onward should prepare using the revised 2027 curriculum.

CFA Level 1 Topic-wise Weightage

The CFA Level 1 topic weights also change in some areas from 2026 to 2027.

From 2027, some topic names also change. Corporate Issuers becomes Corporate Finance, Equity Investments becomes Equities, Derivatives becomes Derivatives and Risk Management, and Portfolio Management becomes Portfolio Construction.

How Many Ethics Questions Are There in CFA Level 1?

The Level I exam contains 180 multiple-choice questions, divided into two 135-minute sessions of 90 questions each. Since topic weights are published as ranges rather than fixed question counts, the number of Ethics questions can only be estimated.

For the 2026 curriculum, this gives an estimated 27–36 Ethics questions. From February 2027, the 10–15% range gives an estimated 18–27 questions.

These figures are estimates, not a fixed number for every exam. The exact topic mix can vary between exam forms.

Where Ethics Sits in the CFA Level 1 Exam Pattern

The CFA Level 1 exam pattern consists of 180 MCQs across two sessions. Each session contains 90 questions and lasts 135 minutes, giving candidates 4.5 hours of testing time in total.

Ethical and Professional Standards is part of Session 1, alongside Quantitative Methods, Economics, Financial Statement Analysis and Corporate Issuers under the 2026 curriculum. From 2027, the Session 1 grouping continues with Corporate Finance replacing Corporate Issuers.

Ethics questions generally present a professional situation and ask you to determine whether conduct complies with the applicable Standard, identify a violation or select the most appropriate action. This makes application practice important alongside reading and revision.

CFA Level 1 Syllabus Ethics: Learning Modules

The CFA Level 1 syllabus ethics content changes between the 2026 and 2027 curricula.

The 2026 curriculum contains five main learning modules. The 2027 curriculum reorganises the topic into more modules, with dedicated treatment of the individual Standards.

2026 CFA Level 1 Ethics Structure

The focus is not simply on memorising the names of the Standards. You need to understand the responsibilities associated with them and apply those requirements to different situations.

2027 CFA Level 1 Ethics Changes

The 2027 curriculum updates Ethics across all three CFA levels. At Level I, the topic is reorganised to separately cover the Code and Standards, Guidance for Standards I through VII and the application of those Standards.

The updated curriculum also reflects the Standards of Practice Handbook, 12th edition. Each Standard receives dedicated treatment with targeted practice opportunities.

What Is an LOS in CFA Ethics?

A Learning Outcome Statement (LOS) describes what you should be able to understand or do after completing a learning module. Ethics LOSs include applying the Code and Standards, identifying violations and recognising practices that can help prevent violations.

This means reading the Standards once is not enough. Your preparation should include questions that require you to apply the rules to different situations.

What Is the CFA Ethics Adjustment?

The ethics adjustment CFA candidates often ask about refers to the role of Ethics performance in borderline results.

When your overall score is very close to the Minimum Passing Score, Ethics performance may influence which side of the passing boundary your result falls on. The exact methodology used for this adjustment is not publicly specified.

How the Ethics Adjustment Works

The key points are:

• Ethics does not have its own passing score.

• The adjustment is relevant to candidates close to the MPS.

• Strong Ethics performance may support a borderline result.

• Weaker Ethics performance may work in the opposite direction.

• The exact adjustment methodology is not published.

Can a Weak Ethics Score Fail You?

There is no separate minimum score for Ethics. A candidate can perform better in some topics and weaker in others because candidates are evaluated on their overall exam performance.

Therefore, a low Ethics performance does not automatically mean that you fail Level I. However, Ethics can become particularly important when your overall result is close to the MPS.

What Is the CFA Minimum Passing Score?

The CFA minimum passing score (MPS) is the overall score required to pass a particular exam administration. It is not a permanent percentage that applies to every CFA exam.

The MPS can be established or maintained through the exam-setting and equating process. Your result includes an overall scale score that allows you to compare your performance with the MPS.

What Does the Score Report Show?

The topic-performance section of the score report presents estimated performance for individual topics with a confidence interval. It also displays 70% and 50% reference lines based on the available points for each topic.

These are not individual topic passing scores. You cannot fail a particular topic and automatically fail the exam. Strong performance in one area can offset weaker performance in another.

Ethics Weightage Across CFA Level 2 and Level 3

Ethical and Professional Standards remains a topic at all three levels of the CFA Program.

The Code and Standards remain central throughout the program, but their application becomes more advanced as you move through the levels. Level II uses item sets, while Level III combines item sets with constructed-response questions.

The 2027 curriculum also updates Ethics across all three levels, so candidates should always prepare from the curriculum applicable to their exam year.

CFA 2027 Curriculum Changes: What Is Different in Ethics?

The CFA 2027 curriculum changes ethics at all three levels. For Level I candidates, the main changes include:

• Ethics weightage moves from 15–20% in 2026 to 10–15% from February 2027.

• The Ethics content is reorganised into more learning modules.

• Standards I through VII receive dedicated treatment.

• Practice is more closely connected to individual Standards.

• Ethics content has been updated across the CFA Program.

• Candidates taking the exam from February 2027 should use the 2027 curriculum rather than relying entirely on 2026 material.

The wider 2027 Level I curriculum also introduces changes in areas such as Quantitative Methods and Equities, so candidates should check the complete curriculum rather than assuming that only the Ethics weightage has changed.

How Much Study Time Should You Give Ethics?

The time you need for Ethics depends on your familiarity with professional standards and how comfortable you are with scenario-based questions. As a practical planning estimate, you can allocate around 35–45 hours across your preparation.

Divide this time into three stages:

• First reading: Understand the Code, Standards and key terminology.

• Application practice: Solve scenario-based questions and identify why conduct is compliant or non-compliant.

• Final revision: Revisit the Standards, common traps and questions you previously found difficult.

Do not complete Ethics once and leave it until the exam. Short revision sessions during your preparation can help you retain the material before moving into intensive final-month practice.

When Should You Study CFA Level 1 Ethics?

Ethics appears near the end of the traditional topic sequence, but that does not mean you should ignore it until the final week.

1. Read Ethics Early

Go through the topic once near the beginning of your preparation. Focus on understanding the Code, Standards and terminology.

2. Keep It Active

Revisit the Standards periodically during your preparation. Short sessions are enough to keep the key rules familiar.

3. Practise More in the Final Month

Use the final three to four weeks for focused scenario-based questions, revision and review of confusing Standards.

4. Revisit the Standards Before the Exam

Close to the exam, pay attention to similar-looking answer choices and situations where a small factual difference changes the correct response.

Why Is CFA Level 1 Ethics Difficult?

Ethics does not rely on the formulas used in topics such as Quantitative Methods or Fixed Income, but it still requires careful application.

1. Similar-Looking Answer Choices

Two options may appear reasonable, but one may better match the specific requirement of a Standard.

2. Scenario-Based Questions

You need to identify the important facts in a situation before deciding whether the conduct is compliant.

3. Broad Coverage

The topic covers the Code, seven Standards, guidance and their practical application.

4. Small Details Matter

Changes in disclosure, client relationships, employer requirements or information available to a professional can affect the correct answer.

5. Practice Is Essential

Reading the Standards helps you learn the rules, while practice questions help you apply them under exam conditions.

The CFA level 1 ethics topic carries substantial weight and can also matter at the borderline through the Ethics adjustment. Check your exam window, use the applicable 2026 or 2027 curriculum, and combine Standards revision with regular scenario-based question practice.
