The CPA Evolution Reality: Divergent Pass Rates Across the Six Papers

Official data following the CPA Evolution overhaul reveals a stark divide in cpa pass rates by section. Candidates are no longer navigating four standardised exams with relatively balanced pass rates; instead, the curriculum bifurcation into three Core papers and three Discipline tracks has created historic swings in performance benchmarks.

Tax Compliance and Planning (TCP) has delivered peak pass rates reaching 76–79%, representing the highest pass rate recorded on any section in modern CPA testing history. At the opposite extreme, Discipline section Business Analysis and Reporting (BAR) and Core section Financial Accounting and Reporting (FAR) have hovered near historic troughs of 39–43%. Meanwhile, Auditing and Attestation (AUD) maintains a challenging 45–50% band, Information Systems and Controls (ISC) settles around 48–52%, and Regulation (REG) tracks reliably at 58–62%.

For UK-based professionals sitting the US CPA at Prometric test centres in London or Manchester—often alongside commitments in the City, Big 4 audit rotations, or prior study for credentials like the ACA or ACCA—these figures are critical. They dictate not only which Discipline paper you should elect, but also how you must sequence your sittings to protect your rolling 30-month credit expiration clock against window constraints.

Official CPA Pass Rates by Section: Core vs Discipline

Under the revised structure, every candidate must clear all three Core exams and select exactly one Discipline. The statistical divide between these papers reflects differences in syllabus depth, candidate self-selection, and examiner scoring dynamics.

Core Exam Benchmarks (Continuous Testing)

The Core papers establish foundational baseline competence across reporting, assurance, and domestic US taxation. Because they operate under continuous testing, scores are processed relatively rapidly, allowing candidates to book retakes with minimal administrative downtime.

  • Financial Accounting and Reporting (FAR): 39–43%
    Historically the primary gateway barrier, FAR continues to record the lowest pass rate among Core papers. Although state boards stripped out advanced consolidations and governmental topics to create the BAR discipline, the sheer volume of US GAAP mechanics, revenue recognition (ASC 606), leases (ASC 842), and complex journal entries continues to depress candidate marks.
  • Auditing and Attestation (AUD): 45–50%
    AUD does not suffer from excessive calculation burdens, but rather from semantic precision and procedural nuance. Evaluated heavily on AICPA Statements on Auditing Standards (SAS), PCAOB standards, and analytical evidence, AUD traps candidates who rely on memorisation rather than audit risk judgements.
  • Regulation (REG): 58–62%
    Covering individual, corporate, and flow-through taxation alongside business law, REG maintains the highest pass rate of the Core papers. Its rules are prescriptive and calculation-driven, rewarding structured question drill repetition.

Discipline Exam Benchmarks (Quarterly Testing Windows)

Unlike Core papers, Discipline exams are administered exclusively during fixed monthly windows: January, April, July, and October. Extended score turnaround lags mean a failed Discipline sitting can consume up to six months of your 30-month credit window.

  • Tax Compliance and Planning (TCP): 76–79%
    TCP represents a hyper-focused extension of REG, drilling deeper into US federal tax compliance, entity restructuring, gift and estate taxes, and international tax provisions. Its elevated pass rate stems from strong syllabus overlap with REG and a high degree of candidate self-selection by corporate tax specialists.
  • Information Systems and Controls (ISC): 48–52%
    Focusing on IT infrastructure, SOC 1/2/3 attestation reporting, cybersecurity frameworks, and data governance, ISC appeals to candidates seeking to avoid heavy computational testing. However, the conceptual and technical definitions in System and Organization Controls make it challenging for those lacking IT audit experience.
  • Business Analysis and Reporting (BAR): 39–43%
    The statistical graveyard of CPA Evolution. Inheriting the most punishing topics pruned from the legacy FAR paper—such as complex derivatives, hedge accounting, state and local government accounting (GASB), and advanced business combinations—BAR features a pass rate lower than any other paper, demanding extreme quantitative stamina.

Difficulty Tier List: Categorising the Six Papers

When mapping your exam plan, viewing papers through a difficulty matrix provides clearer operational insight than looking at raw syllabus volume alone.

Tier 1: High-Attrition Bottlenecks (FAR and BAR)

Both papers feature historical pass rates hovering between 39% and 43%. Candidates fail FAR primarily due to time pressure across multi-tab Task-Based Simulations (TBSs) and cognitive fatigue across 50 detailed computational modules. BAR, by contrast, fails candidates through technical depth: calculating fair value measurements, defined benefit pensions, and fund-accounting conversions under severe time limits. For candidates working long hours in London finance, attempting BAR without substantial pre-existing US GAAP reporting exposure carries disproportionately high failure risk.

Tier 2: The Qualitative Filters (AUD and ISC)

Hovering between 45% and 52%, AUD and ISC test professional judgement and regulatory terminology. In AUD, questions often hinge on a single qualifying word (such as may, should, or must). In ISC, success requires dissecting trust services criteria and internal IT controls without the benefit of calculation work to cross-check answers.

Tier 3: The Predictable Systems (REG and TCP)

With REG at 58–62% and TCP commanding 76–79%, tax-aligned papers offer the most predictable statistical returns. The US Internal Revenue Code is rules-based: once deductions, basis calculations (outside vs inside basis in partnerships), and loss limitation ceilings are mastered, the exam offers fewer subjective traps than AUD or ISC.

The Discipline Decision Matrix: Career Relevance vs Statistical Odds

Selecting your Discipline paper requires balancing immediate passing probability against long-term career positioning.

Choose TCP if: You want the highest statistical probability of clearing your four-part requirement on the first attempt, or you work in corporate tax, private client wealth, or international expatriate planning. If you sit REG first and transition immediately to TCP while tax basis rules remain fresh, you maximise efficiency.

Choose ISC if: You work in internal audit, IT advisory, risk assurance, or tech consulting. ISC avoids advanced mathematical calculations, making it attractive to professionals who struggle with financial accounting mechanics. However, you must be comfortable memorising extensive NIST, COSO, and SOC assurance frameworks.

Choose BAR if: You are an equity research analyst, technical accounting specialist, or transaction advisory consultant whose day-to-day work demands sophisticated mastery of complex financial reporting. Unless you possess this specific career mandate, electing BAR represents an unforced tactical error given its sub-43% pass rate and quarterly window restrictions.

Sequencing Strategy: Protecting Your 30-Month Credit Window

Under revised NASBA and state board policies, candidates generally have 30 months from the date their first passed exam score is released to complete all remaining sections. A poor sequencing strategy risks timing out your earliest credits while you wait for Discipline score releases.

The Recommended Sequence: FAR → AUD → REG → TCP

  1. Start with FAR (Core): Sit FAR first while your mental energy is at its highest. Because the 30-month clock does not activate until you achieve a passing score, absorbing FAR's comprehensive syllabus carries zero downside risk to other credits. Clearing FAR first removes the most formidable cognitive barrier.
  2. Move to AUD (Core): AUD shares conceptual crossover with FAR regarding audit adjustments, internal control assessments, and subsequent events. Continuous testing schedules mean you can sit AUD shortly after completing FAR without waiting for quarterly testing windows.
  3. Transition to REG (Core): REG introduces US tax foundations. Plan this sitting during the quarter preceding a Discipline testing window.
  4. Finish with TCP (Discipline): Schedule TCP in the very next available Discipline window (January, April, July, or October). Because TCP expands directly on REG basis computations and entity tax rules, your required preparation time drops from the standard 120 hours down to roughly 60–80 hours, closing out your qualification with a paper boasting a near-80% pass probability.

If you prefer an advisory or assurance pathway, alternate by sequencing: FAR → AUD → ISC → REG. Schedule ISC immediately following AUD to leverage your understanding of SOC engagements and internal controls, then finish with REG via continuous testing.

Adapting for the UK Market: Overcoming the US GAAP and Tax Gap

Professionals in the UK face two distinct curriculum hurdles not shared by domestic US candidates:

  • IFRS to US GAAP Conversion: UK accounting trainees are trained on IFRS (or FRS 102). In FAR, you must retrain your instincts on key divergences, including LIFO inventory valuation (permitted under US GAAP, prohibited under IFRS), development cost capitalization (strictly expensed under US GAAP), and impairment reversal rules.
  • US Internal Revenue Code (IRC): Unlike general accounting principles, US tax mechanics (S-Corporations, C-Corporations, passive activity loss rules, and 1031 exchanges) have no UK direct equivalent. Attempting to deduce tax law through logic rather than structured retrieval will result in failure.

To master these nuances while working demanding corporate hours, exploring insights on professional exam preparation can help you balance high-volume multiple-choice questions (MCQs) alongside work deliverables.

Executing an AI-Driven Diagnostic Revision Plan

Passing sections with sub-45% clearance rates like FAR and BAR requires moving beyond passive video lectures and uncurated question banks. You need targeted error diagnostics that identify whether your score deficit stems from calculation mechanics, time allocation, or misreading complex TBS exhibits.

You can discover how adaptive learning methods optimise study routines by diagnosing knowledge gaps in real time. Rather than repeating entire chapters, modern preparation focuses on weak-area diagnostic runs: isolating specific sub-topics—such as calculating non-monetary asset exchanges with commercial substance or unravelling lease amortisation schedules under ASC 842.

To build targeted exam endurance for multi-part simulations, engage with adaptive diagnostic question sets that mirror the Prometric interface. Daily active recall and rigorous TBS analysis represent the definitive difference between falling into the 40% failure cohort and securing a comfortable 75+ scaled score across every section.
