The CPA Evolution model introduced one of the biggest changes in CPA exam history: the choice of a discipline section. Instead of the old BEC section, candidates now choose one of three disciplines, BAR (Business Analysis and Reporting), ISC (Information Systems and Controls), or TCP (Tax Compliance and Planning). This choice has real implications for your exam preparation, your pass probability, and potentially your career trajectory. In this guide we break down all three disciplines so you can make an informed decision.
What Each Discipline Covers
BAR: Business Analysis and Reporting
BAR is the most closely related discipline to the old BEC section and to FAR. It covers advanced financial reporting, data analytics, and financial planning topics. Key content areas include:
- Financial statement analysis and ratio analysis
- Technical accounting topics (consolidations, derivatives, fair value)
- Data analytics and data management concepts
- Financial planning and budgeting
- Prospective financial information
- Economic concepts and analysis
BAR is the default choice for many candidates because it feels most "traditional." If you enjoyed FAR or have a strong financial reporting background, BAR extends that knowledge into analysis and planning.
ISC: Information Systems and Controls
ISC is the most distinctive of the three disciplines. It focuses on technology, cybersecurity, and information systems as they relate to accounting and auditing. Key content areas include:
- Information technology governance and frameworks
- Data security, confidentiality, and privacy
- System and organization controls (SOC engagements)
- Network security and cloud computing
- IT audit and assurance procedures
- Data management and business intelligence
ISC is ideal for candidates interested in IT audit, cybersecurity advisory, or technology consulting. It reflects the growing importance of technology in the accounting profession.
TCP: Tax Compliance and Planning
TCP extends the tax content tested on REG into more advanced planning and compliance topics. Key content areas include:
- Advanced individual tax planning
- Entity tax compliance (partnerships, corporations)
- Property transactions and disposition planning
- Tax-advantaged transactions and tax credits
- Compensation and benefits planning
- Estate, gift, and trust taxation
TCP is the natural choice for candidates pursuing careers in tax. If you enjoyed REG or work in a tax practice, TCP allows you to deepen your expertise in an area you will use every day.
Pass Rate Comparison
Since the discipline sections launched in January 2024, initial pass rate data has become available. Here is what we know so far:
- BAR: Approximately 42 to 47 percent. BAR has the lowest pass rate among the three disciplines, likely because of its breadth and overlap with the already-difficult FAR content.
- ISC: Approximately 52 to 58 percent. ISC has shown the strongest pass rates, which may reflect that candidates choosing ISC tend to have specialized IT knowledge.
- TCP: Approximately 55 to 60 percent. TCP pass rates are strong, benefiting from significant content overlap with REG.
It is important to note that these pass rates are still stabilizing. As more candidates take each discipline and review courses continue to improve their coverage, the pass rates may shift. That said, the early trends are meaningful and consistent with what we would expect based on content difficulty and candidate self-selection.
Difficulty Comparison
Difficulty is subjective, but we can compare the three disciplines across several dimensions:
Conceptual Complexity
BAR ranks highest in conceptual complexity. It includes advanced financial reporting topics like derivatives and hedging, consolidation adjustments, and financial analysis. Candidates who struggled with FAR often find BAR similarly challenging. ISC is conceptually unique but not as computationally demanding. TCP is rule-heavy but builds on familiar REG content.
Calculation Load
BAR and TCP both have significant calculation components. BAR requires financial analysis computations, while TCP involves advanced tax calculations. ISC has the lightest calculation load of the three, focusing more on frameworks, controls, and analysis.
Memorization Requirements
ISC requires memorization of IT frameworks, control types, and security concepts. TCP requires memorization of advanced tax rules and thresholds. BAR requires memorization of accounting standards and analytical formulas. All three demand substantial memorization, but the type of content you are memorizing varies significantly.
Career Alignment: Which Discipline Matches Your Path?
While your discipline choice does not restrict your career options (all CPA licenses are equivalent regardless of which discipline you pass), choosing a discipline that aligns with your career goals has practical benefits:
- BAR: Best for candidates pursuing careers in financial reporting, FP&A, corporate accounting, or advisory roles focused on financial analysis.
- ISC: Best for candidates pursuing careers in IT audit, technology consulting, cybersecurity advisory, or internal audit with a technology focus.
- TCP: Best for candidates pursuing careers in tax compliance, tax planning, estate planning, or any role in a tax practice.
If your career goals are not clearly defined, consider which discipline aligns with your strongest academic background. Playing to your strengths maximizes your pass probability.
How to Make the Right Choice
Here is a decision framework:
- Consider your career goals. If you know you want to work in tax, choose TCP. If you want to work in IT audit, choose ISC. If you want to stay in traditional accounting, choose BAR.
- Assess your academic strengths. Which courses did you excel in? If you loved your IT classes, ISC might be natural. If tax was your strongest subject, TCP is a strong fit.
- Look at content overlap. If you found FAR manageable, BAR extends that content. If you performed well on REG, TCP builds on it. If AUD was your strongest core section, ISC connects to AUD's internal controls content.
- Consider pass rates. All else being equal, choosing a discipline with a higher pass rate gives you a statistical advantage. But do not choose a discipline you are unsuited for just because of the pass rate.
- Talk to your employer or mentors. If you are working in public accounting, your firm may have a preference or may offer additional study support for a particular discipline.
Can You Change Your Discipline Choice?
Yes. If you start studying for one discipline and realize it is not the right fit, you can switch. However, any study time you invested in the original discipline is effectively lost, so it is better to make a thoughtful decision upfront than to switch midstream.
Think CPA Covers All Three Disciplines
At Think CPA, we offer comprehensive preparation for BAR, ISC, and TCP. Our materials are designed to match the AICPA blueprint for each discipline, with practice questions and simulations that reflect the actual exam format. Whether you choose the discipline that aligns with your career or the one that plays to your strengths, we have you covered.
Making Your Decision
The discipline choice is less daunting than it seems. Most candidates have a natural lean based on their background and career goals. Trust that instinct, validate it against the data, and commit. The worst thing you can do is delay your exam timeline because you cannot decide. Pick the discipline that fits, start studying, and focus your energy on passing.
