One of the most consequential decisions a CPA candidate makes under the CPA Evolution model is which discipline section to sit for. Unlike the three core sections, which every candidate must pass, the discipline section gives candidates a choice between Business Analysis and Reporting (BAR), Information Systems and Controls (ISC), and Tax Compliance and Planning (TCP).
The decision matters more than most candidates initially realize. Pass rates vary significantly across the three options, the content tested is genuinely different, and the right choice depends heavily on a candidate’s professional background, career direction, and comfort with specific subject matter.
This guide covers what each discipline section actually tests, how pass rates compare, and how to make the decision in a way that gives the best chance of passing efficiently.

Key Takeaways
| Point | Details |
|---|---|
| Every CPA candidate chooses one discipline | Under CPA Evolution, candidates pass FAR, AUD, and REG as core sections, then choose one of BAR, ISC, or TCP as their discipline. |
| Pass rates vary significantly | BAR sits at approximately 42%, ISC at 68%, and TCP at 78%, making the choice a meaningful factor in overall exam efficiency. |
| Background alignment matters | Candidates in audit, advisory, or financial reporting tend to fit BAR. Those in IT or internal controls lean toward ISC. Tax professionals are naturally suited for TCP. |
| The CPA license is identical regardless of discipline | Choosing ISC or TCP does not produce a lesser credential. All three lead to the same CPA license. |
| The hardest section is not always the wrong choice | For candidates with strong BAR-aligned backgrounds, BAR may be faster to pass than a lower-stakes section in unfamiliar territory. |
What Is the CPA Discipline Section Under CPA Evolution?
The CPA Evolution initiative, launched by the AICPA and NASBA, restructured the CPA exam starting in January 2024. The previous four-section model, which included BEC as a standalone section, was replaced with a model built around three core sections and one candidate-chosen discipline.
Every CPA candidate must pass the three core sections:
- FAR (Financial Accounting and Reporting)
- AUD (Auditing and Attestation)
- REG (Taxation and Regulation)
After passing all three core sections, candidates must also pass one discipline section from the following options:
- BAR (Business Analysis and Reporting)
- ISC (Information Systems and Controls)
- TCP (Tax Compliance and Planning)
The discipline section counts toward the same 18-month rolling window as the core sections. Candidates choose their discipline at registration and cannot switch without starting a new exam attempt for that section.
Importantly, the CPA license itself does not differ based on which discipline section a candidate chooses. A candidate who passes TCP receives the same credential as one who passes BAR. The choice is about fit, preparation efficiency, and pass probability rather than the credential value.
BAR Overview: What It Tests and Who It Is For
BAR is the most content-intensive of the three discipline sections. It builds directly on FAR and covers advanced financial reporting, business analysis, and technical accounting topics that go beyond what the core sections require.
What BAR tests:
- Financial statement analysis and interpretation
- Advanced financial reporting topics including segment reporting and interim reporting
- Business combinations and consolidations beyond core FAR coverage
- Financial risk management and derivative instruments
- Managerial and cost accounting
- Economic concepts relevant to business analysis
- Technical research using authoritative accounting literature
BAR simulations are known to be demanding. Many of the task-based simulations require candidates to apply financial analysis skills to realistic scenarios rather than simply recall accounting rules. Candidates who struggle with FAR simulations often find BAR similarly challenging.
Who BAR suits best:
BAR aligns most naturally with candidates working in public accounting audit or advisory roles, financial reporting positions, investment analysis, transaction advisory services, or any role involving deep interaction with financial statements. Candidates with a strong FAR foundation who understand financial statement structure and analysis tend to perform well in BAR even given its difficulty.
ISC Overview: What It Tests and Who It Is For
ISC is a genuinely different section from both BAR and the core sections. Rather than focusing on financial accounting or tax, it tests a candidate’s understanding of information technology systems, internal controls, cybersecurity, and data governance as they relate to the accounting and auditing function.
What ISC tests:
- IT governance and IT general controls
- Information systems and application controls
- Cybersecurity risk and controls
- Data management and analytics
- System and Organization Controls (SOC) engagements
- Business continuity and disaster recovery
- Regulatory frameworks related to data and information security
ISC does have overlap with AUD in areas like internal controls and SOC reporting, which can work in a candidate’s favor if the AUD material is still fresh. However, a significant portion of ISC content covers technology-specific topics that are not addressed in any core section.
Who ISC suits best:
ISC fits candidates working in IT audit, internal audit with a technology focus, advisory services related to controls and compliance, or accounting roles within technology companies. Candidates who have exposure to SOC engagements, IT risk assessments, or cybersecurity frameworks in their professional work often find the material more familiar than expected.
For candidates without any technology background, ISC can feel like studying a foreign subject. The higher pass rate reflects both the section’s structure and the fact that many candidates who choose ISC have relevant professional experience.
TCP Overview: What It Tests and Who It Is For
TCP is the discipline section with the highest pass rate and the most direct overlap with REG, the core section that already covers federal taxation. Candidates who perform well in REG often find TCP to be a manageable extension of material they have already studied.
What TCP tests:
- Advanced individual taxation including complex returns and tax planning strategies
- Tax research and authoritative literature analysis
- Entity taxation including S corporations, partnerships, C corporations, and trusts
- Tax compliance procedures and professional responsibilities
- Multi-jurisdictional taxation concepts
- Tax planning strategies for transactions and investments
TCP goes deeper into tax planning and strategy than REG does. Where REG tests the ability to apply tax rules, TCP emphasizes the ability to analyze situations and recommend tax-efficient approaches. The simulation component often involves tax research using the Internal Revenue Code.
Who TCP suits best:
TCP is the natural choice for candidates working in tax, whether in public accounting, corporate tax departments, or tax advisory roles. Candidates who genuinely enjoy tax and who performed well in REG typically find TCP to be the most straightforward path through the discipline section requirement.
Even for candidates not currently in a tax role, TCP’s strong overlap with REG material means preparation can be efficient if the REG content is still reasonably fresh.
Pass Rates Compared
Pass rate differences across the three discipline sections are substantial and worth factoring into the decision alongside content fit.
| Discipline Section | 2026 Pass Rate | Primary Content Focus | Overlap with Core Sections |
|---|---|---|---|
| BAR | ~42% | Financial reporting, business analysis, advanced accounting | High overlap with FAR |
| ISC | ~68% | IT systems, controls, cybersecurity, data governance | Moderate overlap with AUD |
| TCP | ~78% | Advanced taxation, tax planning, tax research | High overlap with REG |
A few important points about interpreting these numbers:
Pass rate reflects both difficulty and candidate fit. TCP’s high pass rate is partly because most candidates who choose it have a tax background. BAR’s low pass rate is partly because its content is genuinely challenging, and partly because it attracts candidates from audit and advisory backgrounds who may be less prepared for its analytical simulation demands.
A lower pass rate section is not automatically the wrong choice. A candidate with deep financial reporting experience may pass BAR more efficiently than they would pass TCP, even accounting for the pass rate difference. Fit matters as much as raw difficulty.
The 18-month window applies to discipline sections as well. A failed discipline attempt consumes time that affects the entire exam timeline. Pass rate should be a real input into the decision, not an afterthought.
How to Choose Based on Your Career and Background
The most reliable framework for choosing a discipline section is to start with professional experience and then layer in pass rate considerations.
Choose BAR if:
- Your work involves financial statement analysis, audit, transaction advisory, or advanced financial reporting
- You have a strong FAR foundation and feel comfortable with financial analysis
- Your career direction points toward public accounting, investment banking, or corporate finance roles
Choose ISC if:
- Your work involves IT audit, internal audit with technology components, or SOC engagements
- You have exposure to IT general controls, cybersecurity frameworks, or data governance in a professional context
- You are working toward a role in IT advisory, controls consulting, or technology-focused accounting
Choose TCP if:
- You work in tax, whether in public accounting, corporate tax, or advisory
- You performed well in REG and still have that material reasonably accessible
- Your career direction involves tax planning, compliance, or advisory work at any level
For candidates who do not clearly fit any of the three categories, pass rate becomes a more significant factor. In that scenario, TCP’s preparation overlap with REG and its higher pass rate make it a reasonable default for many candidates.
Candidates who want a personalized recommendation before registering can explore the one-on-one tutoring services at Andrew Katz Tutoring, where discipline section selection is part of the initial consultation process. Tutoring is available for all three discipline sections, and candidates who want to understand what BAR tutoring involves specifically can request a session focused on that section.
What If You Are Still Not Sure?
Choosing a discipline section without a clear professional fit is genuinely difficult, and it is worth taking time to think through the decision rather than defaulting to whichever option seems easiest at first glance.
A few practical steps that help:
Review the AICPA blueprints for each section. The CPA Exam Blueprints published by the AICPA provide a detailed breakdown of what each discipline section tests and at what skill level. Reading through the BAR, ISC, and TCP blueprints side by side gives a clearer picture of which content feels most familiar.
Look at sample questions. Most review course providers offer sample questions for each discipline section. Spending an hour on sample questions for each option is more informative than reading descriptions alone.
Consider your timeline. If the 18-month window is tight, the section with the highest pass rate given your background should carry more weight. A failed discipline attempt at the end of an otherwise completed exam can be particularly costly.
Talk to someone who has taken your preferred section. Candidates who have recently passed BAR, ISC, or TCP can provide perspective on preparation time, difficulty relative to the core sections, and what actually showed up on their exam.
Candidates who want structured guidance on both the discipline selection decision and the preparation plan can review the tutoring packages and rates at Andrew Katz Tutoring before scheduling a consultation.
Key Takeaways
The discipline section decision is one that every CPA candidate under CPA Evolution will face, and it is worth approaching carefully. BAR demands the most from candidates but suits those with strong financial reporting backgrounds. ISC is the right fit for candidates with technology and controls experience. TCP offers the clearest overlap with existing core section material and the highest pass rate, making it a strong choice for tax professionals and a reasonable option for candidates without a strong fit in the other two.
No discipline section leads to a stronger or weaker CPA license. The credential is the same regardless of which path is chosen. The goal is to choose the option that aligns with professional background, maximizes preparation efficiency, and fits within the exam timeline.

FAQ
Can I switch my discipline section after registering?
No. Once a candidate registers for a discipline section, they cannot switch without completing or forfeiting that attempt. The decision should be made before registration, not after.
Does the discipline section I choose affect my CPA license?
No. The CPA license is identical regardless of which discipline section a candidate passes. BAR, ISC, and TCP all lead to the same credential.
Which discipline section is the easiest to pass?
Based on 2026 pass rates, TCP has the highest pass rate at approximately 78%, followed by ISC at 68% and BAR at 42%. However, ease depends heavily on a candidate’s background. A tax professional may find TCP straightforward, while a candidate with no tax background could find it harder than BAR despite the pass rate difference.
Does the discipline section have to be passed within the 18-month window?
Yes. The discipline section is subject to the same 18-month rolling window as the three core sections. All four sections must be passed within 18 months of passing the first one.
What happens if I fail my discipline section?
A failed discipline section attempt does not void any previously passed core sections, but it does consume time within the 18-month window. Candidates can retake the discipline section as soon as the next testing window opens after their score is released.
