AICPA CPA Exam in 2026: Core Sections, Disciplines and the CPA Evolution Model

The Uniform CPA Examination now operates under the CPA Evolution Core-and-Discipline model. Every candidate must pass three Core sections—Auditing and Attestation (AUD), Financial Accounting and Reporting (FAR), and Taxation and Regulation (REG)—and then pass one of three Discipline sections: Business Analysis and Reporting (BAR), Information Systems and Controls (ISC), or Tax Compliance and Planning (TCP).

The Discipline choice does not create a restricted form of CPA license. AICPA states that candidates reach the same CPA licensure outcome regardless of which Discipline they pass. The choice is therefore a preparation and professional-interest decision, not a permanent legal specialization.

The three Core sections define knowledge every new CPA needs

AUD evaluates auditing and attestation knowledge, professional responsibilities, evidence, risk assessment, internal control, and the reasoning needed to perform or support assurance work. FAR focuses on financial accounting and reporting across business, not-for-profit, and governmental contexts. REG covers U.S. federal taxation, ethics and professional responsibilities related to tax practice, and business-law concepts. Candidates who understand audit readiness and evidence as a connected process are better able to see why control design, testing, documentation, and conclusions must agree.

For broad CPA Exam preparation, candidates should use the current AICPA blueprint to determine what is testable in their planned window because the examination is updated through blueprints and policies on new pronouncements.

These Core sections are intentionally broad. A candidate may eventually work in audit, tax, advisory, industry, or government, but the CPA Exam still requires a common foundation before the Discipline choice adds depth.

BAR, ISC and TCP let candidates choose an area of additional depth

BAR is aligned with business analysis, financial statement analysis, advanced reporting topics, and related accounting and performance decisions. It is a logical option for candidates whose study and work are already strong in financial reporting, analysis, and technical accounting.

ISC focuses on information systems, business controls, security, confidentiality, privacy, processing integrity, and technology-related assurance. Candidates considering ISC should be comfortable with how systems support financial processes and how controls are designed and tested. Broader IT auditing context can help connect control terminology with the work performed in technology and assurance roles. The underlying data security and privacy controls matter because access, retention, encryption, masking, and auditability are part of the evidence environment that technology assurance examines.

TCP extends tax knowledge into more complex compliance and planning for individuals and entities. It suits candidates who are already strong in taxation and want deeper work with nonroutine transactions, entity planning, and personal financial-planning considerations.

Do not choose a Discipline by pass rate alone

AICPA’s published pass-rate data can look very different across BAR, ISC, and TCP, but AICPA explicitly cautions that the numbers reflect candidate preparedness and self-selection rather than providing a simple ranking of exam difficulty. Candidates should not assume that the section with the highest recent pass rate is automatically the safest choice for them.

A better decision uses coursework, work experience, and genuine subject strength. A tax professional may have a strong base for TCP. Someone working with systems, SOC engagements, security, or technology controls may find ISC more natural. A candidate with advanced financial-reporting and analysis experience may prefer BAR. Choosing the Discipline that aligns with existing knowledge reduces the amount of entirely new material that must be built under exam pressure.

Scoring and preparation reward applied reasoning

AICPA reports CPA Exam scores on a 0–99 scale, with 75 required to pass a section. A score of 75 is not the same thing as answering 75 percent of questions correctly. Scores combine performance across multiple-choice questions and task-based simulations using the examination’s scoring methodology.

That makes simulation practice essential. Candidates should be able to research within provided authoritative material where applicable, organize exhibits, identify relevant facts, perform calculations, and document a conclusion. The challenge is often not knowing one rule in isolation but applying several rules to a messy set of facts while ignoring irrelevant information.

• Build the study plan from the current AICPA blueprint for the exact testing period.
• Use cumulative review so earlier Core topics remain available when simulations combine subjects.
• Practice task-based simulations under time limits, including document-heavy scenarios.
• Choose the Discipline using background and career interest rather than pass-rate headlines.
• Track state-board eligibility and licensure requirements separately from AICPA exam-content requirements.

The CPA Exam is only one part of licensure

The AICPA develops and scores the Uniform CPA Examination, while eligibility and licensure are governed through U.S. boards of accountancy and related state or jurisdictional requirements. Education, experience, ethics, application procedures, and credit-retention rules can therefore differ by jurisdiction.

Candidates should keep two checklists: one for the exam and one for licensure. The exam checklist covers AUD, FAR, REG, the chosen Discipline, scheduling, and score progress. The licensure checklist covers the rules of the jurisdiction where the candidate intends to qualify. Keeping those processes separate prevents a common mistake—finishing the examination only to discover an unmet education or experience requirement afterward.

Use the Core-and-Discipline model to build one coherent study system

The CPA Exam’s structure encourages candidates to think in layers. AUD, FAR, and REG establish the common foundation expected of newly licensed CPAs, while BAR, ISC, or TCP adds depth in an area that can align with education, experience, or professional interest. The Discipline is not a separate license, and the CPA’s professional practice is not legally confined to the Discipline passed. The choice should therefore improve preparation fit rather than be treated as a permanent career label.

Core knowledge overlaps more than section names suggest. An audit simulation may require the candidate to understand the accounting behind a balance before evaluating evidence. A tax issue can affect financial reporting. An internal-control question can involve systems, authorization, data, and documentation. Candidates who study each section in isolation may know individual rules but struggle when a task-based simulation requires several of them at once.

BAR extends that integration toward analysis, reporting, technical accounting, state and local government accounting, and data-driven business decisions. ISC deepens technology assurance, information systems, SOC engagements, data management, security, and privacy. TCP deepens tax compliance and planning for individuals and entities. The best Discipline is usually the one for which the candidate already has a foundation strong enough to support advanced application.

Section sequencing can also be strategic. Candidates may choose to take a Core section while related coursework or work experience is fresh, then move into the Discipline that benefits most from that foundation. The important point is to preserve cumulative knowledge: FAR concepts can support BAR, control and audit knowledge can support ISC, and REG can support TCP. A study sequence should exploit those relationships instead of treating each new section as a complete reset.

Blueprints, simulations, and licensure rules create three separate planning tracks

The first track is content. Candidates should build their plan from the current AICPA blueprints for the testing period, because the blueprints define the skills and representative tasks that can be assessed. As new accounting, auditing, tax, and technology guidance enters the profession, AICPA uses its policies and blueprint updates to determine when material becomes testable. Old notes should therefore be mapped to the current blueprint rather than assumed to remain complete.

The second track is exam execution. Task-based simulations require candidates to navigate exhibits, determine which facts are relevant, perform calculations or research where appropriate, and produce an answer that matches the exact requirement. Preparation should therefore include document-heavy practice, not just question banks. Candidates should rehearse a consistent workflow: read the task first, inventory the exhibits, mark assumptions, complete the work, and reserve time to check whether every response field has been addressed.

The third track is jurisdictional licensure. State and other U.S. boards of accountancy determine eligibility, education, experience, ethics, and related licensure rules. A candidate can be academically ready for the CPA Exam while still needing to resolve a jurisdiction-specific education or application issue. Keeping a separate licensure checklist prevents the exam plan from hiding requirements that AICPA itself does not control.

Technology should be treated as part of accounting practice rather than an ISC-only subject. Systems produce the records used in reporting, tax, and audit; access controls affect who can change data; automated processes can create both efficiency and risk; and analytical tools can change how evidence is evaluated. Even candidates who choose BAR or TCP benefit from understanding how data is created, controlled, transformed, and relied upon.

A durable CPA study strategy therefore alternates depth with integration. Learn one blueprint area well, practice questions until the reasoning is stable, then revisit it inside cumulative mixed sets and simulations. The final goal is not merely to recognize a rule but to decide which rule matters, apply it to incomplete facts, document the reasoning, and move on under time pressure—the same shift from knowledge to judgment that the Core-and-Discipline model is designed to measure.

Error analysis can make the final weeks of CPA preparation much more efficient. Candidates should classify missed questions by cause: knowledge gap, misread requirement, calculation error, failure to use an exhibit, weak time management, or uncertainty between two plausible rules. A notebook full of correct explanations is less useful than a record that shows why errors repeat. The goal is to remove the process failures that continue costing points even after technical knowledge improves.

It is also useful to practice stopping rules. In a timed exam, one difficult simulation can consume enough time to damage performance elsewhere. Candidates should learn when to make a defensible assumption, document the work completed, and move forward. That discipline does not mean guessing carelessly; it means managing limited time while preserving accuracy where it matters most. Professional examinations reward both judgment and execution, and the CPA Exam is no exception.
