The 2024 CPA Exam Evolution: What Changed and Why It Matters in 2026
The CPA exam structure changed in 2024. Two years in, the patterns of who passes, who struggles, and how the new disciplines play out are clearer. Here's what 2026 candidates need to know.
The CPA Evolution model launched in January 2024 and is now two years into production. The structural change matters because it shapes how candidates choose to specialize, which content gets emphasized, and where the difficulty has settled. Here's the 2026 read.

What changed
| Pre-2024 | 2024+ |
|---|---|
| 4 sections, all candidates | 3 cores + 1 discipline (chosen) |
| AUD, FAR, REG, BEC | AUD, FAR, REG cores + BAR, ISC, or TCP discipline |
| BEC tested broad business | BEC eliminated; content redistributed |
| Equal weighting | Cores still 4 hours; disciplines 4 hours |
Where the BEC content went
- Cost/managerial and financial management moved primarily to BAR.
- IT general controls and information systems moved primarily to ISC.
- Economics and corporate governance distributed across cores.
- Written communication tasks were eliminated entirely (no more BEC essays).
The three disciplines, in plain language
- BAR (Business Analysis and Reporting): Deeper dive into financial management, cost accounting, data analytics, and complex financial reporting. Closest in spirit to the more advanced FAR topics. Common pick for candidates targeting industry FP&A or technical accounting roles.
- ISC (Information Systems and Controls): IT general controls, SOC engagements, IT audit. Common pick for candidates targeting audit-tech, IT advisory, or risk-and-controls work.
- TCP (Tax Compliance and Planning): Federal tax, individual and entity-level. Closest to traditional REG-but-deeper. Common pick for candidates targeting tax practice.
Two-year retrospective: what we know in 2026
Pass rates settled in
Pass rates fluctuated heavily through 2024 as candidates and review courses calibrated. By 2026 the rates have stabilized. Cores remain the more challenging sections; FAR is still the most-failed.
Discipline choice patterns
BAR and TCP have drawn the largest discipline candidate populations. ISC has remained smaller, partly because of perceived difficulty and partly because it doesn't map onto a traditional career track for candidates outside of audit-tech or IT advisory.
Review course adaptation
All major review courses (Becker, Surgent, Wiley, Gleim, UWorld) had rough first-year coverage of the disciplines, especially ISC and BAR. By 2026 the content has matured. If you're studying with material released before mid-2024, replace it.
What this means for 2026 candidates
- Pick your discipline based on career fit, not perceived difficulty. The pass-rate gap has narrowed; the long-term career signal of "I'm the BAR specialist" vs "I'm the ISC specialist" matters more than scoring optimization.
- Plan for the FAR/REG/AUD trio first. All candidates take all three; treat them as the foundation.
- Take the discipline last. It's the section where you can lean most heavily on whatever specialization you're moving toward.
- Don't buy old materials. Pre-2024 content covers BEC, which doesn't exist anymore.
The 18-month credit window
You must pass all four sections within 18 months of passing your first. Several states have proposed extending this to 24 or 30 months in 2026; check your state's current rule. The window applies uniformly across cores and discipline.
Continuous testing
Continuous testing remains in effect — you can sit for any section nearly any business day. Retakes after a fail are allowed in the next testing window, typically within weeks rather than months as it was pre-2020.
Frequently asked questions
What did the 2024 CPA Evolution change?
The exam moved from four equally-weighted sections (AUD, FAR, REG, BEC) to three core sections (AUD, FAR, REG) plus one chosen discipline (BAR, ISC, or TCP). BEC was eliminated; its content was redistributed across cores and disciplines. The new structure took effect January 2024.
Which discipline is easiest?
Pass rates and difficulty perception varied significantly through 2024-2025. ISC was widely seen as having the highest pass rate; BAR had the lowest. By 2026 the gap has narrowed as study materials matured. Pick based on career fit and your existing strengths, not perceived difficulty.
Is the discipline permanent on my CPA record?
Yes. Whichever discipline you pass becomes part of your CPA designation. It does not legally restrict the type of work you can do as a CPA, but it does signal a specialization. Most candidates pick the discipline that matches their first-job track.
