CPA Exam Sections Explained: AUD, FAR, REG, and Your Discipline

A complete reference to the four CPA Exam sections under the CPA Evolution model: the three required Core sections AUD, FAR, and REG, the three Discipline options BAR, ISC, and TCP, and how each section is formatted, weighted, and scored.

What are the sections of the CPA Exam?

The CPA Exam has four sections: three required Core sections - Auditing and Attestation (AUD), Financial Accounting and Reporting (FAR), and Taxation and Regulation (REG) - plus one Discipline section you choose from BAR, ISC, or TCP. Each section runs four hours and mixes multiple-choice questions with task-based simulations. You must pass all four to be licensed.

This structure comes from the CPA Evolution model, which the AICPA and NASBA launched in January 2024 to replace the old four-fixed-section exam. The idea is a strong common Core that every CPA shares, plus one area of deeper focus that reflects how the profession has specialized around technology, analysis, and tax. You pass three Core sections and exactly one Discipline - never all three Disciplines - so the total is always four sections and 16 hours of testing.

The rest of this guide breaks down what each section covers, how it is formatted, how the exam is scored, and how long you have to finish all four. For the full backstory of why the exam changed, see our CPA Evolution 2024 explainer.

  • •Core (required, pass all three): AUD, FAR, REG.
  • •Discipline (pick one): BAR, ISC, or TCP.
  • •Total: four sections, four hours each, 16 hours of testing, 75 to pass each.

What are the three Core CPA sections?

The Core is the shared foundation every CPA candidate must pass, regardless of which Discipline they later choose. It covers the three pillars of public accounting practice: auditing, financial reporting, and taxation and regulation. Because all three are mandatory, most candidates build their study plan around the Core first and slot the Discipline in where it best complements their strongest area.

Each Core section is a self-contained four-hour exam with its own blueprint of content areas, its own mix of multiple-choice questions and task-based simulations, and its own passing bar of 75. Below is what each one tests at a glance; the detailed content-area weights follow further down this guide.

AUD - Auditing and Attestation

The full audit and attestation lifecycle: professional ethics and responsibilities, assessing risk, performing procedures and gathering evidence, and forming conclusions and reporting. Heavy on judgment and the reasoning behind audit decisions rather than rote calculation.

FAR - Financial Accounting and Reporting

Financial statements and the standards behind them: financial reporting frameworks, balance sheet accounts, and select transactions. Widely regarded as the broadest, most computation-heavy Core section, which shows in its pass rate.

REG - Taxation and Regulation

Federal taxation and business law: ethics and tax procedures, business law, property transactions, individual taxation, and entity taxation. If you enjoy REG, the TCP Discipline is a natural extension of the same material.

How do you choose a CPA Discipline section?

After the three Core sections, you sit exactly one Discipline of your choice. All three lead to the same CPA license and none restricts what you can practice once licensed, so the choice is about playing to your strengths and interests rather than locking in a specialty. Think about which body of material you already know best, which Core section you found most comfortable, and where your intended career leans.

The three options branch out from the Core in predictable directions: BAR extends FAR into deeper analysis and reporting, ISC builds on the technology and controls world, and TCP is the tax specialist's continuation of REG. Pick the one whose subject matter you would rather study for another four hours, because that alignment usually matters more than a headline pass-rate gap.

BAR - Business Analysis and Reporting

Business analysis, deeper technical accounting and reporting, and state and local government accounting. A fit for candidates who liked FAR and want an analytical, reporting-focused path. It carried the lowest 2025 cumulative pass rate of the six sections.

ISC - Information Systems and Control

Information systems and data management, security and privacy, and SOC engagements. The only section not weighted 50:50; it leans more toward multiple-choice. Suits candidates comfortable with IT, controls, and audit technology.

TCP - Tax Compliance and Planning

Individual and entity tax compliance, entity tax planning, and property transactions - a deep get into the tax world REG introduces. It posted the highest 2025 cumulative pass rate, which partly reflects the tax-focused candidates who self-select into it.

How is each CPA section formatted?

Every CPA section combines two question types: multiple-choice questions (MCQs) and task-based simulations (TBSs). MCQs test recall and applied understanding; TBSs are longer, scenario-driven tasks that ask you to work through documents, fill in schedules, or reason toward a conclusion the way you would on the job. For five of the six sections the two types split the score evenly, 50:50. ISC is the single exception, weighting MCQs more heavily at 60:40.

The table below shows the published question counts and score weighting for each section. One important caveat: these MCQ and TBS totals include unscored pretest items that the AICPA embeds to trial future questions, so not every question you answer counts toward your score, and you cannot tell which is which. The counts are stable for the 2026 to 2027 blueprint but the AICPA can revise them at blueprint updates.

What content areas does each CPA section test?

Each section has a published blueprint that divides its material into content areas, each carrying a weight range that tells you roughly how much of the exam it drives. The ranges are intentionally bands rather than fixed percentages, because the exact mix varies from one test form to the next. Use them to prioritize: the higher the weight, the more of your study time that area deserves.

Below are the blueprint content areas and their weight ranges for all six sections. Read your chosen four - the three Core sections plus your Discipline - as the skeleton of your study plan, and notice where the heaviest bands sit before you decide how to sequence your prep.

  • •AUD: Ethics and Professional Responsibilities 15-25%; Assessing Risk and Developing a Planned Response 25-35%; Performing Procedures and Obtaining Evidence 30-40%; Forming Conclusions and Reporting 10-20%.
  • •FAR: Financial Reporting 30-40%; Select Balance Sheet Accounts 30-40%; Select Transactions 25-35%.
  • •REG: Ethics, Professional Responsibilities and Federal Tax Procedures 10-20%; Business Law 15-25%; Federal Taxation of Property Transactions 5-15%; Federal Taxation of Individuals 22-32%; Federal Taxation of Entities 23-33%.
  • •BAR: Business Analysis 40-50%; Technical Accounting and Reporting 35-45%; State and Local Governments 10-20%.
  • •ISC: Information Systems and Data Management 35-45%; Security, Confidentiality and Privacy 35-45%; Considerations for SOC Engagements 15-25%.
  • •TCP: Individual Tax Compliance and Planning 30-40%; Entity Tax Compliance 30-40%; Entity Tax Planning 10-20%; Property Transactions 10-20%.

How is the CPA Exam scored?

Every section is scored on a scale from 0 to 99, and you need a 75 to pass. That 75 is a passing threshold, not a percentage of questions answered correctly. Your score is a weighted, scaled score that combines your performance on the MCQs and the TBSs according to each section's weighting - 50:50 for five sections and 60:40 for ISC - so two candidates who answer the same number of questions correctly can score differently depending on which questions those were.

The exam is not curved against other candidates. Your result reflects only your own answers measured against a fixed standard, which means there is no advantage or penalty from testing alongside a strong or weak cohort. Because the score is scaled rather than raw, you cannot reverse-engineer an exact percent-correct target; the practical goal is consistent competence across the whole blueprint, since a weak content area can quietly pull a scaled score below 75. For how these thresholds translate into results across sections, see our CPA exam pass rates breakdown.

  • •Scale: 0 to 99, with 75 as the passing mark for every section.
  • •A 75 is a scaled, weighted score, not a raw 75 percent correct.
  • •The exam is not curved - you are measured against a fixed standard, not other candidates.

How long do you have to pass all four CPA sections, and when can you sit them?

Once you pass your first section, a rolling window opens: under the rule most jurisdictions have now adopted, you have 30 months - measured from the score-release date of that first pass - to clear the remaining three sections. Miss the deadline and your oldest credit expires, forcing a retake. This 30-month window replaced the legacy 18-month rule, giving candidates meaningfully more breathing room, but adoption and the exact mechanics can vary by state board, so confirm the current policy with your own jurisdiction.

Scheduling differs between Core and Discipline. The three Core sections test year-round under continuous testing, and you can retake a failed Core section as soon as its score is released. The Discipline sections are the exception: BAR, ISC, and TCP are offered only in the first month of each calendar quarter - January, April, July, and October. That window shapes sequencing, because if you fail a Discipline you cannot retake it immediately; you wait for the next quarter's opening month. Many candidates therefore clear the Core first and time their single Discipline attempt carefully.

  • •Rolling 30-month window from your first passed section's score-release date to finish the other three (up from the old 18 months).
  • •Core sections (AUD, FAR, REG) test year-round with continuous retakes once a score is released.
  • •Discipline sections (BAR, ISC, TCP) are offered only in the first month of each quarter: January, April, July, October.

Which CPA section should you take first?

There is no mandated order, so strategy comes down to the 30-month clock, the year-round availability of the Core, and your own strengths. A common approach is to open with FAR - the broadest section and, on 2025 numbers, one of the toughest - so that the hardest material is behind you and the 30-month window starts on your terms. Others prefer to bank an early win with a section they feel strong in, then use that momentum. Either way, sit a Core section first, because Core availability is year-round while the Discipline is locked to quarter openings.

Let the pass rates inform, not dictate, your sequence. The table below shows 2025 full-year cumulative rates by section. They fluctuate quarter to quarter and reflect who self-selects into each section, so they are a planning input rather than a difficulty ranking - our how-hard-is-the-CPA guide unpacks that nuance.

Frequently Asked Questions

How many sections are on the CPA Exam? +
Four. Under the CPA Evolution model that has been live since January 2024, every candidate passes three required Core sections - AUD, FAR, and REG - plus one Discipline section chosen from BAR, ISC, or TCP. You take four sections in total, not six; the three Discipline options are alternatives, so you sit only the one you select. Each section is a separate four-hour exam scored on its own.
What is the difference between Core and Discipline sections? +
The three Core sections - Auditing (AUD), Financial Accounting and Reporting (FAR), and Taxation and Regulation (REG) - are mandatory and test the foundational knowledge every CPA needs. The Discipline section lets you go deeper in one area: business analysis and reporting (BAR), information systems and control (ISC), or tax compliance and planning (TCP). Whichever Discipline you pass, you earn the same single CPA license.
Which CPA Discipline section is easiest? +
There is no official easiest Discipline, and difficulty is personal. That said, 2025 full-year cumulative pass rates from the AICPA put TCP highest at 77.65% and ISC next at 67.79%, while BAR was lowest at 41.94%. Pass rates fluctuate quarterly and reflect who self-selects into each section, so treat them as one input alongside your own background rather than a ranking of raw difficulty.
How long is each CPA Exam section? +
Every section is four hours long, for a total of 16 hours of testing across the four sections. Each one combines multiple-choice questions (MCQs) with task-based simulations (TBSs). The four hours cover the exam content itself; you also receive a standardized break and check-in time at the test center or online, which does not count against your four hours of testing.
What score do you need to pass each CPA section? +
You need a 75 on each section. Scores run on a 0 to 99 scale, and 75 is the passing mark for all four sections. A 75 is not a raw 75 percent correct; it is a weighted, scaled score that combines your MCQ and TBS performance. The exam is not curved against other candidates, so your result depends on your own answers, not the size of the testing pool.
How long do you have to pass all four CPA sections? +
Under the rolling window most jurisdictions now use, once you pass your first section you have 30 months - measured from the score-release date - to pass the remaining three, or the oldest credit expires. This replaced the legacy 18-month window. Adoption and exact mechanics can vary slightly by state board, so confirm the current rule with your own jurisdiction before you plan your sequence.
Can you take the CPA Discipline sections any time of year? +
Not quite. The three Core sections (AUD, FAR, REG) test year-round under continuous testing. The Discipline sections (BAR, ISC, TCP) are offered only in the first month of each calendar quarter - January, April, July, and October. That scheduling limit matters when you plan your sequence, because a Discipline retake can only happen in the next quarter's opening month, not immediately.
How much does each CPA section cost? +
Fees are set by your individual state board of accountancy, not uniformly by the AICPA, so the exact figure depends on your jurisdiction. As an approximate 2025 to 2026 guide, many boards charge in the region of 350 to 400 US dollars or more per section, plus an initial application or registration fee. International testing adds surcharges. Verify the current amounts on your state board or NASBA before you register.
