What each Discipline covers

Every candidate passes one Discipline. Per the January 2026 Blueprints:

Business Analysis and Reporting (BAR): Area I Business Analysis 40-50%; Area II Technical Accounting and Reporting 35-45%; Area III State and Local Governments 10-20%. BAR goes deeper into financial statement analysis, technical accounting and governmental reporting than FAR.

Information Systems and Controls (ISC): Area I Information Systems and Data Management 35-45%; Area II Security, Confidentiality and Privacy 35-45%; Area III Considerations for System and Organization Controls (SOC) Engagements 15-25%.

Tax Compliance and Planning (TCP): Area I Tax Compliance and Planning for Individuals and Personal Financial Planning 30-40%; Area II Entity Tax Compliance 30-40%; Area III Entity Tax Planning 10-20%; Area IV Property Transactions (disposition of assets) 10-20%.

Skill mix and format differ

Discipline	MCQs / TBSs	Remembering and Understanding	Application	Analysis
BAR	50 / 7	10-20%	45-55%	30-40%
ISC	82 / 6	55-65%	20-30%	10-20%
TCP	68 / 7	5-15%	55-65%	25-35%

ISC leans on knowledge of systems, security and SOC concepts, with more MCQs and a 60% MCQ score weight. BAR and TCP lean on application and analysis, with MCQs and TBSs weighted 50/50.

The choice does not limit your license

ThisWayToCPA, the AICPA's candidate site, states it plainly: the license says CPA and does not name the Discipline you passed, and passing one Discipline does not restrict future practice. You can pass TCP and build an audit career. The Discipline choice is a study decision, not a career contract.

Testing windows shape the calendar

Core sections can be scheduled year-round. NASBA's FAQ states that Discipline sections can be scheduled only in the first month of each quarter, and the AICPA reports Discipline scores about six weeks after each window closes. A failed Discipline attempt costs at least one quarter before the retake. Factor that into the credit window.

A decision method that holds up

Start with your work. Tax staff who prepare entity returns already practice most of TCP Area II. IT audit and SOC staff see ISC content daily. Staff in financial reporting, advisory or governmental audit find BAR closest to their files.
Look at Core overlap. BAR builds on FAR. TCP builds on REG. ISC builds on the information technology and data content in AUD.
Check the timing. Sit the Discipline right after the Core section it overlaps with, and pick a window that does not collide with busy season.
Read the Blueprint tasks. ThisWayToCPA recommends starting with coursework, experience and interests, using the Blueprints when unsure, and choosing on fit rather than on which section looks easiest.

Mistakes to avoid

Choosing by published pass rate alone. Pass rates reflect who sits for a section as much as its difficulty.
Missing the window. Booking a Discipline for the second month of a quarter is not possible.
Picking BAR without strong FAR fundamentals; its Application and Analysis share is 75-95%.

The section guide compares the sections side by side, and the credential comparison helps staff who are weighing other certifications.

Worked example

Two staff members, two Disciplines

Marcus Lee works on SOC 2 examinations at Northgate Assurance LLP. Elena Ruiz prepares partnership and S corporation returns at the same firm. Both passed REG and FAR in the spring.

Marcus compares ISC Area III (SOC engagements, 15-25%) and Area II (security, confidentiality and privacy, 35-45%) with his engagements. At the midpoints, 20% + 40% = 60% of ISC overlaps his daily work. He picks ISC and books the first month of the next quarter.

Elena compares TCP Area II (entity tax compliance, 30-40%) and Area III (entity tax planning, 10-20%). Midpoints: 35% + 15% = 50% of TCP overlaps her work, and the rest builds on the individual and property tax content she just studied for REG. She picks TCP.

Timing check for both: Discipline windows fall in the first month of each quarter, and scores come about six weeks after the window closes. If either fails a January attempt, the earliest retake window is April. Conclusion: both choose the Discipline with the greatest work overlap and sit it in the first available window after their last Core section.

Self-check

Answer each question before you open the answer.

Does a CPA who passed ISC have any limit on providing tax services after licensure?
Show answer
No. The license says CPA and does not specify the Discipline; the AICPA states that passing one Discipline does not restrict future practice.
Which Discipline has the highest share of Remembering and Understanding questions?
Show answer
ISC, at 55-65% of the section. BAR and TCP place most of their weight on Application and Analysis.
A candidate fails BAR in a January window. When is the earliest retake month, and why?
Show answer
April. Discipline sections are scheduled only in the first month of each quarter, and the candidate also must receive the January score before retaking under the board’s rules.
Which Core section does BAR build on most directly?
Show answer
FAR. BAR’s technical accounting and state and local government areas extend the financial reporting content tested in FAR.
