How Hard Is the CPA Exam? Pass Rates by Section, Difficulty & What Candidates Say

The CPA Exam is widely considered the most difficult professional licensing exam in accounting. A roughly 50% first-attempt pass rate per section means that even well-prepared candidates frequently fail at least one section before completing all four. Understanding the specific nature of the difficulty — and how it varies by section — helps you prepare appropriately and maintain realistic expectations.

Key Facts

• Overall pass rate per section: ~40–50% (varies by section and exam window)
• FAR pass rate: ~40–45% (consistently lowest)
• AUD pass rate: ~47–52%
• REG pass rate: ~45–50%
• BAR pass rate: ~48–53% (newer section; limited historical data)
• Passing score: 75 (scaled, not percentage correct)
• Total study time for all 4 sections: 300–500 hours typical

Pass Rate Data: The Full Picture

Historical Pass Rates by Section

The AICPA and NASBA release pass rate data quarterly. The following ranges reflect recent years under both the pre-Evolution and Evolution formats:

| Section | Recent Average Pass Rate | |---------|--------------------------| | FAR (Financial Accounting and Reporting) | 40–45% | | AUD (Auditing and Attestation) | 47–52% | | REG (Regulation) | 45–50% | | BAR (Business Analysis and Reporting) | 48–53% | | ISC (Information Systems and Controls) | 50–55% | | TCP (Tax Compliance and Planning) | 47–52% |

BAR, ISC, and TCP were introduced in January 2024 and have limited historical data. Ranges are approximate.

What These Rates Mean

A 40–50% pass rate means that over any given exam window, more candidates fail each section than pass it. This is higher than many licensing exams in other fields but lower than professional exams like the Bar Exam (national average approximately 55–60% [from training data, may be outdated]).

The multi-section structure amplifies the difficulty: even if you have a 60% chance of passing each section on any given attempt, the probability of passing all four sections on first attempts is 0.60^4 = approximately 13%. Most candidates should plan for multiple attempts across sections.

The "75" Passing Score Context

The passing score is 75 on a 0–99 scaled score. This is not 75% correct — it is a scaled score that adjusts for item difficulty. The AICPA's research has determined that 75 on this scale represents the minimum competency level for a newly licensed CPA.

What this means practically: focusing on score accuracy (how many questions you get right) rather than the raw percentage is the right approach. Reviewing wrong answers and understanding why you missed them is more important than tracking a raw percentage.

Section-by-Section Difficulty Analysis

FAR: The Hardest Section

FAR is universally recognized as the hardest CPA Exam section. The reasons:

Breadth: FAR covers U.S. GAAP for public companies (ASC standards), governmental accounting (GASB standards), not-for-profit accounting (ASC 958), SEC reporting requirements, and IFRS comparisons. Each of these is a significant body of knowledge on its own.

Depth within each area: The GAAP coverage includes complex topics like business combinations (ASC 805), leases (ASC 842), revenue recognition (ASC 606), derivatives and hedging (ASC 815), and many others. Each has specific measurement and disclosure requirements.

Technical complexity: FAR requires more computation than other sections. Earnings per share, bond amortization, goodwill impairment testing, and government fund accounting all involve multi-step calculations.

Time pressure: A 4-hour FAR exam that covers this breadth creates meaningful time pressure, especially given the TBS tasks.

Recommendation: Allocate the most study hours to FAR (120–150 hours is common) and take it early in your testing window when your accounting knowledge is freshest.

AUD: Conceptual but Demanding

AUD is often described as more conceptual than computational — you need to understand professional standards, risk assessment frameworks, and audit evidence principles rather than calculate precise answers.

What makes AUD hard:

• Professional standards memorization: PCAOB AS and AICPA AU-C sections have specific requirements that must be known
• Conceptual ambiguity: Many AUD questions have answers that depend on subtle distinctions in professional judgment
• Simulation complexity: AUD TBSs often involve evaluating audit documentation, assessing whether procedures are appropriate, or drafting sections of audit reports

AUD rewards candidates who have actual audit experience — the real-world context makes the professional judgment calls more intuitive. For candidates without audit experience, the conceptual framework must be built from scratch through study.

REG: Memorization Marathon

REG is the most memorization-intensive section. Tax law is specific and rule-bound: phase-out thresholds, character of income distinctions, entity-specific rules, and timing of recognition all have precise answers that must be known, not estimated.

What makes REG hard:

• Volume of tax rules: Individual, corporate, S-corp, partnership, estate and gift, exempt organizations — each has different rules that must be kept separate
• Specificity: The correct answer to a tax question often depends on a specific threshold or rule that has no intuitive logic
• Business law: The business law component adds another knowledge domain (contracts, agency, bankruptcy, commercial paper) to an already dense section

REG benefits most from spaced repetition practice — doing questions, reviewing rules, and returning to the same rules multiple times across your study period.

BAR: The New Broad Section

BAR (Business Analysis and Reporting) is the most commonly chosen discipline section and covers a blend of financial analysis, technical accounting, and managerial accounting topics.

What makes BAR distinctive:

• Data analytics tasks: BAR includes scenarios requiring analysis of business data, financial ratios, and performance metrics in more complex ways than other sections
• Technical accounting breadth: Business combinations, variable interest entities, and other advanced topics tested in BAR are challenging
• Breadth without equivalent depth: BAR covers many topics at moderate depth rather than few topics at great depth

BAR's pass rates have been somewhat higher than FAR since the Evolution format launched, suggesting it may be moderately less difficult on average — though limited historical data makes this comparison preliminary.

The CPA Evolution Format: How It Changed Difficulty

What Changed for Task-Based Simulations

The CPA Evolution format increased the complexity of task-based simulations to better reflect the skills required in modern accounting practice. Notable changes:

• TBSs now include more realistic workplace scenarios requiring professional judgment
• Data analytics tasks appear in BAR requiring interpretation of structured data
• Document review tasks (analyzing contracts, financial documents, client communication) are common in AUD and REG TBSs
• Research tasks using the authoritative literature (FASB Codification, IRC, PCAOB standards) continue to be important

Net effect: TBSs are harder in the Evolution format and are weighted more significantly in the scoring. Candidates who prepare primarily by practicing MCQs are less prepared for the actual exam than those who specifically practice TBSs.

What Changed for MCQs

MCQs in the Evolution format continue to emphasize higher-order thinking skills (analysis, evaluation) rather than pure recall. This reflects the AICPA's stated goal of testing whether candidates can apply knowledge to realistic situations, not just memorize facts.

The Unique Challenges of the CPA Exam

The 18-Month Window Pressure

No other major professional exam has a comparable testing window requirement. The CPA's 18-month window — pass all four sections within 18 months of passing the first — creates scheduling and strategic pressure that adds to the perceived difficulty.

Failing any section requires retaking it before the window closes or risk losing earlier credits. This pressure is psychological as well as logistical.

The Education and Experience Requirements

The CPA requires 150 semester credit hours and (in most states) 1–2 years of qualifying work experience. For candidates who are simultaneously working toward these requirements while studying for the exam, the total life management challenge is significant.

Exam Security and Environment

CPA Exam sections are delivered at Prometric testing centers under strict conditions. The exam environment (multiple sections of candidates in the same room, headphones, restricted materials) is more controlled and potentially more stressful than academic testing environments most candidates are familiar with.

Who Takes the CPA Exam (and Why It Matters for Pass Rates)

The Candidate Pool

CPA Exam candidates are primarily:

• Recent accounting graduates (Bachelor's or Master's)
• Working accounting professionals seeking the license
• Candidates returning from study breaks

Unlike the CFA Level II (where everyone has already passed Level I), the CPA candidate pool includes first-time takers who may be less prepared than average.

The pool also includes significant numbers of retakers at each exam window. NASBA data suggests that retakers constitute approximately 40–50% of candidates at some sections. Retakers who have not changed their preparation strategy often fail again — contributing to the reported pass rate.

The Advantage of Relevant Work Experience

Candidates who work in roles directly related to the exam content consistently outperform those without relevant experience. An auditor at a Big Four firm studying for AUD has daily reinforcement of the exam content. A corporate accountant studying for FAR works with the accounting standards every day.

If your work is directly relevant to one or more sections, expect to study fewer hours for those sections than the average estimates suggest.

What Candidates Consistently Report

Across forums (r/CPA, another71, CPAREVIEWFORUM), candidate experiences show consistent patterns:

"FAR is a marathon, not a sprint." The most common description of the FAR experience. The breadth of content and the time required to master it exceeds what most candidates initially expect.

"I failed AUD because I didn't take the TBSs seriously." A recurring theme in AUD failures. Candidates who score well on MCQs but neglect TBS practice often fail. AUD TBSs require specific document and evidence evaluation skills.

"REG is rule after rule after rule." The memorization load of tax law is the most frequently cited challenge. Candidates who work in tax find it significantly more manageable.

"I felt better about my chances after my first attempt, even though I failed." The exam experience itself is educational. Many candidates who fail a section report that the next attempt benefits from knowing exactly what the exam demands.

"The TBSs took longer than I expected." Time management on TBSs is a consistent challenge. Practice with actual TBS tasks before the exam is essential.

How Does the CPA Compare to Other Professional Exams?

| Exam | Pass Rate (Approx.) | Study Hours (Typical) | Unique Challenge | |------|--------------------|-----------------------|-----------------| | CPA (per section) | 40–52% | 70–150/section | 18-month window; 4 sections | | Bar Exam (MBE) | 55–65% | 400–600 total | Written essays; multi-day | | CFA Level I | 40–45% | 300+ total | 10 topics in one sitting | | CFA Level II | 40–45% | 300+ (after L1) | Vignette format; deep content | | FRM Part I | 45–50% | 200+ | Quantitative emphasis | | Series 65 | ~70–75% | 100–150 | Lower threshold |

The CPA is competitive with the most difficult professional licensing exams in other fields. The multi-section structure with a time window is a unique challenge that has no direct equivalent in the other major credentialing programs.

FAQ

Q: Is failing a CPA Exam section common? A: Very common. With pass rates of 40–52%, most candidates fail at least one section on their first attempt. Many candidates fail multiple sections before completing all four. This is normal and expected, not a sign of inability.

Q: Which section should I take first to maximize my chances? A: Most prep providers recommend FAR first because it is the hardest and benefits from being taken when accounting knowledge is freshest (close to your accounting education). However, this is a general recommendation — if you work in tax, starting with REG may be more natural.

Q: How much do pass rates vary between exam windows? A: Pass rates fluctuate by 3–7 percentage points across quarters and years. There is no consistent evidence that specific quarters (Q1 vs. Q3) are systematically easier. Schedule based on your readiness, not on trying to time an "easier" window.

Q: Does having a Master of Accountancy help compared to just a Bachelor's? A: Candidates with a Master of Accountancy (MAcc) or Master of Taxation typically have deeper content knowledge in specific areas and often pass on fewer total attempts. However, a well-prepared Bachelor's-level candidate with good study materials passes just as effectively.

Q: Is the CPA Exam harder for international candidates? A: International candidates who earned their accounting education outside the U.S. may find REG and FAR harder due to U.S.-specific regulations and standards. Language proficiency is an additional challenge for candidates whose primary language is not English. Some state boards accept international accounting credits; check your specific state board's requirements.
