1.1 CPA Evolution Model

The 2026 Core Plus Discipline Model

The Uniform CPA Examination now uses the CPA Evolution model, launched in January 2024 and unchanged in form for 2026. The exam is no longer the four-section AUD, BEC, FAR, and REG battery. Instead, every candidate passes three required Core sections and one self-selected Discipline section, for four passed sections total.

The three Core sections are Auditing and Attestation (AUD), Financial Accounting and Reporting (FAR), and Taxation and Regulation (REG). Every candidate sits all three. The Discipline choices are Business Analysis and Reporting (BAR), Information Systems and Controls (ISC), and Tax Compliance and Planning (TCP). You pick exactly one.

This matters for planning: your study calendar covers four sections, not six. A common rookie error is budgeting time for all three Disciplines. You choose one, prepare it deeply, and pair it with the three Core passes.

Section Format

Every section uses five testlets in a fixed order: the first two are multiple-choice question (MCQ) testlets, and the final three are task-based simulation (TBS) testlets. Within each section a subset of items is pretest (unscored). REG, for example, presents 72 MCQs of which 60 are operational and 12 are pretest, plus 8 TBSs of which 7 are operational. You cannot tell which items are pretest, so answer every one as if it counts.

What Changed From The Old Exam

The old Business Environment and Concepts (BEC) section no longer exists. Its content did not vanish; it was redistributed. Advanced business analysis, financial-statement metrics, and governmental accounting moved into BAR. Internal control, IT general controls, cybersecurity, privacy, and System and Organization Controls (SOC) engagements moved into ISC. Higher-complexity tax compliance and planning moved into TCP. The written-communication tasks BEC once used were retired entirely.

The deeper shift is conceptual: the exam now tests a common baseline every newly licensed CPA needs (the three Core sections) plus one area of deeper competence (the Discipline). Data and technology concepts are woven across all sections, not quarantined in ISC.

Choosing A Discipline

Discipline choice should be practical, not emotional. Anchor it to your strongest Core base, your work experience, and the unfamiliar-content burden you are willing to absorb.

1. Strong in FAR, comfortable with ratios, financial analysis, and governmental accounting? Lean BAR.
2. Strong in AUD, internal controls, IT, or SOC reporting? Lean ISC.
3. Strong in REG and tax-return logic, especially nonroutine planning? Lean TCP.
4. Employer preference matters, but remember the Discipline does not create a limited license.
5. Use pass-rate data carefully: rates reflect the candidate pool and prep level, not raw difficulty.

Worked Example: Building A Four-Section Plan

Suppose a candidate works in a tax department, finds REG concepts intuitive, but struggles with the breadth of FAR. A sound plan sequences sections to ride momentum and protect the credit window. One disciplined approach:

1. Sit FAR first while motivation and study stamina are highest, because FAR is the broadest Core section and feeds BAR concepts.
2. Sit AUD second, leveraging the financial-reporting foundation FAR builds.
3. Sit REG third, the candidate's strongest area, as a confidence builder.
4. Sit TCP last as the Discipline, because REG study primes the advanced individual, entity, and property-transaction tax content TCP demands.

This ordering also limits credit-window exposure: passing your hardest section first starts the clock when you are freshest, rather than risking expiration on FAR after three other passes. A candidate strong in audit and IT might instead run AUD, then ISC, then FAR, then REG. The point is that section order is a strategic lever, not an afterthought.

Common Traps

• Treating the Discipline as a career cage. It is not. All four passes yield one identical CPA license; the Discipline never limits future practice areas.
• Assuming fewer MCQs means an easier section. FAR and BAR each have only 50 MCQs but carry dense, computation-heavy content and the lowest pass rates.
• Forgetting BEC content did not disappear. Economics, internal control, and IT concepts migrated into BAR and ISC and still appear in Core sections; do not skip them because "BEC is gone."
• Studying content before architecture. Candidates who open FAR chapters before knowing which Discipline they will take often waste weeks reviewing material outside their four-section plan.

One CPA License

The Discipline section is an exam requirement, not a license label. Passing BAR does not make you a "BAR CPA," and passing TCP does not confine you to tax practice. After licensure all CPAs hold the identical credential and may practice in any area where they maintain competence and due care under professional standards. Treat Chapter 1 as orientation: know the four sections you must pass and how each is built before you open a single content chapter.
