- The CB exam has no fixed annual "testing windows" - Prometric appointments for Parts 1 and 2 are booked year-round.
- Parts 1 and 2 are timed (2 hours each, 75% to pass); Parts 3 and 4 are untimed, open-book workbook finals (70% to pass).
- A failed Prometric part can be retaken after a mandatory 30-day wait for a $60 fee; workbook retakes cost nothing.
- Once you pass all four parts, you have 3 years to document 2 years full-time or 3,000 part-time/freelance hours of experience.
Why "Testing Windows" Work Differently for the CB Exam
If you're used to certification exams with fixed quarterly testing windows and hard application deadlines, the Certified Bookkeeper (CB) exam works differently. The American Institute of Professional Bookkeepers (AIPB) does not run seasonal testing cycles. Instead, Parts 1 and 2 of the national certification exam are delivered on demand through Prometric testing centers, meaning you schedule your own appointment whenever you're ready - there's no application deadline to miss and no "next window" to wait for in 2026.
Parts 3 and 4 remove the scheduling question entirely. These are open-book, back-of-the-workbook final exams that you complete on your own time, with no proctor and no time limit. That structure changes how you should think about "exam dates" for the CB: instead of circling a single test day on the calendar, you're really planning a sequence of four milestones spread across your own self-study pace.
Scheduling Parts 1-4: Prometric vs. Workbook Finals
Understanding the four-part structure is essential before you touch a calendar. Parts 1 (Adjusting Entries) and 2 (Error Correction) are administered at Prometric centers, each with a strict 2-hour time limit and a 75% passing grade. Parts 3 (Payroll) and 4 (Depreciation, plus Inventory and Internal Controls content folded into the later workbooks) are completed as open-book finals at the back of your workbooks, with a 70% passing threshold and no clock running.
Practically, this means your scheduling decisions split into two categories:
- Prometric appointments (Parts 1 & 2): Require advance booking, photo ID, and a testing-center visit. Build in buffer time for availability at your local center.
- Workbook finals (Parts 3 & 4): Submitted whenever you finish the corresponding workbook - no appointment needed, so these can flex around your work and life schedule.

Building Your 2026 Registration-to-Certification Timeline
Because there's no external deadline forcing your hand, most candidates who stall out do so from a lack of self-imposed structure - not from missing a registration window. A realistic 2026 timeline usually looks like this:
Enroll and Order Workbooks
- Enroll through AIPB and receive all six workbooks
- Review the Code of Ethics requirement early - it's mandatory for certification
Master Adjusting Entries and Error Correction
- Work through Domain 1 and Domain 2 workbooks in depth
- Schedule your first Prometric appointment for Part 1 once practice scores are consistently above 75%
Sit Part 2 and Begin Payroll
- Book Part 2 (Error Correction) at Prometric
- Start the Payroll workbook, the largest of the six
Complete Workbook Finals
- Submit Part 3 (Payroll) final once workbook exercises are solid
- Move into Depreciation, Inventory, and Internal Controls content, then submit Part 4
This pacing isn't mandatory - some candidates move faster, others slower - but it illustrates the point: your 2026 "exam dates" are self-scheduled milestones, not AIPB-imposed deadlines. For a more granular week-by-week approach, see the CB Study Guide 2026: How to Pass on Your First Attempt.
Retake Deadlines If You Fail a Part
The one place where a real deadline-style rule does apply is retakes. If you fail Part 1 or Part 2 at Prometric, AIPB requires a mandatory 30-day waiting period before you can retest, along with a $60 retake fee. This waiting period is the closest thing the CB exam has to an official "cooldown" date - mark it on your calendar the moment you get a failing score so you know exactly when you're eligible to rebook.
Workbook final retakes (Parts 3 and 4) work differently and more forgivingly: there is no fee and, unlike Prometric, no mandatory 30-day wait - you resubmit once you've reviewed the material. This asymmetry is a strong argument for tackling the timed Prometric parts only when you're truly ready, since a slip-up there costs both time and money.
Key Takeaway
If you fail Part 1 or Part 2, immediately note the date - you're locked out of retesting for 30 days and will owe $60 to rebook. Use that mandatory wait productively by drilling weak spots identified in How Hard Is the CB Exam? Complete Difficulty Guide 2026.
Fees, Deadlines, and What Each Dollar Covers
Budgeting matters as much as scheduling. The official self-study path totals $479 for AIPB members and $574 for nonmembers. That price includes enrollment, all six workbooks, and two $100 Prometric fees (one for each timed part). There's no expiration date attached to this initial fee - you don't lose your investment if your personal timeline stretches across most of 2026.
| Cost Item | AIPB Members | Nonmembers |
|---|---|---|
| Total self-study package | $479 | $574 |
| Includes | Enrollment, six workbooks, two $100 Prometric fees (Parts 1 & 2) | |
| Prometric retake fee (after 30-day wait) | $60 per attempt | |
| Workbook final retake fee (Parts 3 & 4) | None | |

The 3-Year Experience Clock After You Pass
Here's a scheduling detail many candidates overlook: passing all four exam parts is not the finish line. Certification also requires signing the AIPB Code of Ethics and documenting at least 2 years of full-time bookkeeping experience, or 3,000 hours of part-time/freelance experience. If you haven't already met that experience threshold when you pass, AIPB gives you 3 years after your passing date to complete it.
This means your real "final deadline" isn't a test date at all - it's the 3-year window to accumulate qualifying hours. If you're a newer bookkeeper studying for the exam in 2026 without much on-the-job history yet, you can technically pass the exam now and spend the next few years building experience toward final certification. Full eligibility mechanics, including how hours are verified, are covered in CB Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Scheduling Study Time Around the Six CB Domains
Since the exam itself has no fixed date pressure, the smarter question for 2026 candidates is: in what order should you schedule mastery of the six CB domains? The workbooks are structured around these areas, and AIPB's own timed-test priority - adjusting entries, error correction, payroll, and depreciation - should dictate your sequence.
Domain 1: Mastering Adjusting Entries
Tested on Part 1 at Prometric under a strict 2-hour clock. Candidates must be fast and accurate with accruals, deferrals, and end-of-period adjustments.
- Highest scheduling priority - book this Prometric slot only after timed practice consistently clears 75%
Domain 2: Mastering Correction of Accounting Errors
Also timed on Part 1's companion section. Requires quick identification of error types and correcting entries under pressure.
- Pair study sessions with Domain 1 since both appear on the same timed Prometric part
Domain 3: Mastering Payroll
Covered on Part 3, an untimed, open-book workbook final. Still demands deep familiarity with wage calculations, deductions, and tax deposits.
- Schedule generous time here - it's the largest content area of the six workbooks
Domain 4: Mastering Depreciation
Tested on Part 4. Untimed but conceptually dense, covering depreciation methods and asset schedules.
- Study alongside Inventory since both roll into the same final workbook
Domain 5: Mastering Inventory
Costing methods and inventory valuation appear throughout the later workbooks feeding into Part 4.
- Lower timed-test priority, but still required for full workbook completion
Domain 6: Mastering Internal Controls and Fraud Prevention
Rounds out the workbook curriculum with fraud-prevention concepts and control procedures.
- Schedule last - reinforces material from all prior domains

Ongoing Deadlines: CPECs and Recertification
Your scheduling responsibilities don't end once you're certified. AIPB requires 60 CPECs (Continuing Professional Education Credits) every 3 years to maintain the CB designation. Unlike your original exam dates, this is a recurring, rolling deadline - mark your certification anniversary on a calendar now so 2026's momentum doesn't get lost three years down the road.
Employers evaluating candidates for bookkeeping, accounts payable/receivable, or full-charge bookkeeper roles often check that CPEC status is current, since a lapsed designation signals inattention to maintenance requirements. If you're weighing how the credential affects hiring and pay over time, CB Salary Guide 2026: Complete Earnings Analysis and CB Jobs both cover how employers use the credential in practice.
Key Takeaway
Set two calendar reminders once you pass: one for the 3-year experience documentation window, and one for your first 60-CPEC recertification deadline three years after certification.
What to Expect on Prometric Test Day
Since Parts 1 and 2 are the only proctored, date-and-time-specific portions of the CB exam, day-of logistics matter. Prometric centers allow nonprinting, nonprogrammable, self-powered calculators - confirm yours qualifies before your appointment, since anything programmable or with printing capability will be turned away at check-in. Arrive with valid photo ID matching your registration exactly, and plan to arrive early; Prometric centers often run multiple certification exams simultaneously, and check-in queues can eat into your buffer time before your 2-hour clock starts.
Because there's no way to "reschedule for the next window" the way you might with a quarterly-cycle exam, missing or rescheduling a Prometric appointment simply means booking a new slot - subject to center availability, which can vary seasonally near local college terms or busy accounting periods (like January-April tax season, when many test-takers also work in accounting). Booking a few weeks ahead of your target date, rather than the week before, gives you more flexibility in 2026.
FAQ: CB Exam Dates and Scheduling
No. Parts 1 and 2 are scheduled individually through Prometric on a rolling, on-demand basis - there are no quarterly or annual testing windows. Parts 3 and 4 have no scheduling requirement at all since they're untimed workbook finals.
AIPB does not impose a fixed deadline for completing all four parts. Your workbooks and enrollment don't expire on a set date, so your personal pace determines your timeline.
You must wait 30 days after a failed attempt on Part 1 or Part 2 before retesting, and you'll pay a $60 retake fee. Workbook final retakes for Parts 3 and 4 have no waiting period and no fee.
You have 3 years from your passing date to document 2 years of full-time bookkeeping experience, or 3,000 hours of part-time/freelance experience, along with signing the AIPB Code of Ethics.
Yes - maintaining the CB designation requires earning 60 CPECs every 3 years. This is a recurring deadline tied to your certification anniversary, not your original exam dates.
Whatever pace you set for 2026, the absence of fixed testing windows is actually an advantage: it lets you schedule Prometric appointments around when your domain mastery is genuinely ready, rather than a calendar forcing your hand.
