Which CPA discipline should you choose?
TCP has the highest CPA discipline pass rate at 79.53% and BAR the lowest at 43.64%, a spread of 35.89 points on the AICPA 2026 rates through Q2.
All three lead to the same unrestricted CPA license. The discipline is a section of the exam, not a specialization recorded on the credential, so the choice is about which exam you are most likely to pass and which material you would rather spend months in.
The three disciplines
| Section | Name | Pass rate | Covers |
|---|---|---|---|
| TCP | Tax Compliance and Planning | 79.53% | Discipline: advanced individual and entity tax compliance and planning. Pairs well with a tax career. |
| ISC | Information Systems and Controls | 67.45% | Discipline: IT governance, SOC engagements, security, and controls. Pairs well with an advisory or IT-audit path. |
| BAR | Business Analysis and Reporting | 43.64% | Discipline: advanced financial reporting, data analysis, and financial management. Pairs well with an assurance or reporting path. |
The part worth pausing on
BAR passes at 43.64%, within 0.69 points of FAR, the hardest core section. Choosing BAR means sitting two of the three hardest sections on the exam. That can still be the correct choice if the material matches your work, because familiarity is worth more than a headline rate, but it should be a decision rather than a default.
What the choice commits you to
Can a discipline section replace one of the core sections?
No. A discipline is a fourth section, not an alternative to a core. NASBA states that candidates "will be required to pass AUD, FAR and REG", so every candidate sits all three cores whichever discipline they pick.
Can you take more than one CPA discipline section?
You may sit more than one, but you keep credit for only one. NASBA's rule is that candidates "are allowed to pass and retain credit for only one Discipline section". Passing a second does not add anything to your record, so there is no reason to sit one you do not need.
Can you change your CPA discipline after failing one?
Yes. If you fail a discipline you may select a different one to test in instead, and you may also change if a discipline credit expires. Failing BAR does not commit you to BAR. That matters more than it sounds, because the discipline is the only section you choose, and a first attempt that goes badly is information about the fit rather than a door closing.
The disciplines are also the sections with the tightest calendar: they are administered in the first month of each quarter only, so a failed discipline waits for the next quarterly sitting. Scheduling, the NTS and retakes covers what that does to a retake.
