Choosing a CPA discipline is the single most underrated decision in the entire CPA Exam process. Pick the one that fits your background and the section can feel almost familiar by exam day. Pick the wrong one and you might find yourself fighting low pass rates, unfamiliar content, and a delayed license. With the 2026 CPA Exam now fully settled into its CPA Evolution structure, this guide breaks down BAR, ISC, and TCP so you can pick confidently and pass the first time.

CPA Evolution and the Three Discipline Sections
Since January 2024, every CPA candidate must pass three Core sections (Auditing and Attestation, Financial Accounting and Reporting, and Regulation) plus one Discipline section of their choice. The Discipline section earns you the same CPA license no matter which one you pick. Your license does not display the discipline you chose. The choice is entirely about playing to your strengths and matching the kind of work you want to do.
Each Discipline exam is 4 hours long with 50 percent multiple choice questions and 50 percent task based simulations. You have an 18 month rolling window to pass all four sections after passing your first one. Discipline sections are offered in quarterly testing windows, each about one month long, so missing a window can cost you three full months of progress.
BAR: Business Analysis and Reporting
BAR is the most “FAR like” of the three Disciplines, which is both its blessing and its curse. About 40 percent of the section covers financial statement analysis and reporting topics that build directly on the Core FAR section. The remaining content includes governmental accounting, employee benefit plans, lease accounting, derivatives, and revenue recognition under ASC 606. Pass rates for BAR have hovered in the low 40 percent range, similar to FAR.
Pick BAR if you are heading into: financial planning and analysis, corporate accounting, technical accounting, audit at a public accounting firm where complex SEC reporting is common, treasury, or any role where deep GAAP knowledge matters every day.
Skip BAR if: you struggled with FAR or found research and analysis questions exhausting. BAR amplifies both.
BAR Content Areas (rough weighting)
- Business Analysis: 40 to 50 percent
- Technical Accounting and Reporting: 35 to 45 percent
- State and Local Governments: 10 to 20 percent
ISC: Information Systems and Controls
ISC is the most modern of the three Disciplines and the only one that goes deep on technology, IT general controls, SOC engagements, and cybersecurity. About 60 percent of the test covers information systems concepts and SOC reporting, with the rest dedicated to data management, controls testing, and security frameworks like NIST and COBIT. Pass rates have stabilized in the low to mid 50 percent range as candidates have figured out the section, making ISC the highest pass rate option for many test takers.
Pick ISC if you are heading into: IT audit (internal or external), SOC 1 and SOC 2 reporting, cybersecurity advisory, technology consulting, ERP implementation work, data governance, or risk advisory at a Big Four firm.
Skip ISC if: you have zero comfort with IT terminology and have never worked with controls testing. The vocabulary alone can be steep if you are coming from a pure accounting background.
ISC Content Areas (rough weighting)
- Information Systems and Data Management: 35 to 45 percent
- Security, Confidentiality, and Privacy: 35 to 45 percent
- Considerations for System and Organization Controls Engagements: 15 to 25 percent
TCP: Tax Compliance and Planning
TCP is the deep tax dive that builds directly on the Core REG section. Roughly half of TCP covers individual taxation including more advanced topics like alternative minimum tax, gift tax, and personal financial planning. The other half handles entity tax compliance and planning, including partnership and S corporation taxation, C corp distributions, and consolidated returns. TCP has consistently posted the highest pass rates of the three Disciplines, often in the 75 to 80 percent range, which has made it the popular default for tax candidates.
Pick TCP if you are heading into: public accounting tax, corporate tax, private wealth advisory, estate planning, partnership taxation, or any role where tax research is core to the day to day work.
Skip TCP if: you barely survived REG, have no tax internship or job experience, and find tax code citations frustrating rather than satisfying.
TCP Content Areas (rough weighting)
- Tax Compliance and Planning for Individuals and Personal Financial Planning: 30 to 40 percent
- Entity Tax Compliance: 30 to 40 percent
- Entity Tax Planning: 10 to 20 percent
- Property Transactions (Disposition of Assets): 10 to 20 percent
How to Choose the Right Discipline
Three filters cut through the noise quickly:
- Career match. Your discipline should reflect the work you actually want to do. A future tax associate in a Big Four firm should pick TCP. A future IT auditor should pick ISC. A future financial reporting analyst should pick BAR. Recruiters do not look at which discipline you took, but the prep itself becomes useful background for the first six months on the job.
- Strength of your Core sections. Look at how you scored on FAR and REG. If FAR was your strongest Core, BAR will feel manageable. If REG felt like the easiest Core, TCP is a natural extension. If both felt brutal but you have any tech aptitude, ISC gives you a fresh start with the highest reported pass rates.
- Pass rate realism. Pass rates do not predict your individual outcome, but they do tell you how much margin you have for off days. TCP at 78 percent forgives more than BAR at 42 percent.
Best Order to Take the Four Sections
Once you choose your discipline, the order you take the four sections has a real impact on your 18 month window. The pattern most successful candidates follow:
- FAR first. It is the longest content set and the most foundational. Passing it first frees mental space and starts your 18 month clock with the hardest section out of the way.
- Your Core that pairs with your discipline next. If you chose BAR, take FAR then BAR back to back so the financial reporting content stays fresh. If you chose TCP, take REG then TCP. If you chose ISC, take AUD then ISC, since both lean on controls thinking.
- Remaining Cores last. The two leftover Core sections can be cleaned up at the end. Their content is more self contained and less interdependent.
The “pair your discipline with its closest Core” principle is the highest leverage scheduling decision. Studying for FAR and BAR within four months of each other shaves dozens of study hours off the second exam.
Building a 16 Week Discipline Study Plan
Most candidates need 120 to 180 hours per Discipline section, spread across roughly 16 weeks at 8 to 12 hours per week. The schedule below scales for any of the three Disciplines.
Weeks 1 through 4: Lecture and Reading
Cover roughly 30 percent of the syllabus per week. Use a single review course (Becker, Surgent, Roger, UWorld, or similar) and resist the urge to mix providers, which doubles your time without doubling your retention.
Weeks 5 through 10: Practice and Review
Shift to 70 percent question practice. Aim for 1,500 to 2,000 multiple choice questions during this phase. Review every wrong answer the same day, and write a one sentence note about why it was wrong. Patterns will emerge.
Weeks 11 through 14: Task Based Simulations
Task based simulations are 50 percent of your score. Most candidates undertrain them because they take longer per question. Schedule 10 to 15 simulations per week during this phase, and time yourself strictly. The Authoritative Literature research function deserves dedicated practice. Knowing where to look in FASB Codification (BAR) or the Internal Revenue Code (TCP) saves real minutes on test day.
Weeks 15 and 16: Mock Exams and Polish
Take two full length mock exams under realistic conditions. Score yourself, identify your two weakest content areas, and spend the final week doing targeted review. Avoid heavy new content in the last 5 days. Sleep, hydration, and exam day logistics matter more than one more chapter.
Common Mistakes That Sink Discipline Scores
- Picking based on pass rates alone. A 78 percent pass rate on TCP does not help if you have never touched tax. Career and Core strength filters come first.
- Letting your Core knowledge go cold. Take your discipline within 4 months of the related Core. After 6 months the related material starts to fade and you lose your foundation.
- Skipping simulations. They are half the score and the most common reason candidates fall just short of 75. If you can pass simulations consistently, you can pass the section.
- Studying part time forever. Three hours a week for 40 weeks is worse than 12 hours a week for 14 weeks. Momentum compounds; trickle studying does not.
- Ignoring the testing window calendar. Discipline sections only run during specific quarterly windows. Schedule your section during the open registration period, then build your study plan backward from that date.
Frequently Asked Questions
Does my CPA license show which discipline I picked?
No. The CPA license is identical for all three disciplines. Employers, state boards, and clients see “Certified Public Accountant” on your credential, not the discipline name.
Can I switch disciplines after I start studying?
You can change your mind any time before sitting for the exam. You only commit when you submit your Notice to Schedule. Switching wastes prep time, however, so try to lock in your pick before you start serious study.
Which discipline is the easiest?
By pass rate, TCP has been the easiest, followed by ISC, then BAR. By content load, ISC arguably has the smallest body of memorization. “Easiest” still depends on your background. A tax professional finds TCP easy. A tech focused candidate finds ISC easy. There is no universal answer.
How long should I study for a Discipline section?
Plan for 120 to 180 hours over 14 to 18 weeks. Candidates who pass on the first attempt average closer to the high end of that range, while repeat takers often skim closer to the low end and pay for it.
Are there testing window blackouts in 2026?
Discipline sections are offered in 4 quarterly testing windows, each about one month long. Outside those windows you cannot sit. Core sections are available continuously. Plan your Notice to Schedule around the discipline calendar, since that is the binding constraint.
What if I fail my discipline?
You can retake any section as soon as the next testing window opens, and your other passing scores stay valid as long as you finish all four sections within your 18 month window. Most candidates who fail by 5 points or fewer pass on the second attempt with focused remediation in the weak content areas.
