- Parts 1-2 are Prometric tests with a 75% pass mark and a 2-hour limit each.
- Parts 3-4 are open-book workbook finals with a 70% pass mark and no time limit.
- Self-study runs $479 (AIPB members) or $574 (nonmembers), including both $100 Prometric fees.
- Adjusting entries, error correction, payroll, and depreciation carry the highest timed-test priority.
Exam Structure at a Glance
The Certified Bookkeeper credential is administered by the American Institute of Professional Bookkeepers (AIPB), and its national exam is split into four multiple-choice parts that don't all behave the same way. Parts 1 and 2 are delivered at Prometric testing centers, each capped at a 2-hour limit, and each requiring a 75% passing grade. These two parts test the material under real exam pressure - no notes, no open book, just recall and calculation speed.
Parts 3 and 4, by contrast, are open-book finals located in the back of the official workbooks. There's no time limit on these, and the passing grade drops slightly to 70%. This structural split matters enormously for how you should prepare: cramming for Parts 1 and 2 like a closed-book Prometric test while treating Parts 3 and 4 as a relaxed take-home exercise is exactly the right instinct. For a deeper breakdown of what's tested inside each part, the CB Exam Domains 2026: Complete Guide to All 6 Content Areas maps every content area to its corresponding exam part.
Fees and Registration Fast Facts
Budgeting for the CB credential is simple once you know the official numbers. The self-study track totals $479 for AIPB members and $574 for nonmembers. That figure includes:
- Enrollment in the self-study program
- All six official prep workbooks
- Both required $100 Prometric fees (for Parts 1 and 2)
There's no separate line-item cost for Parts 3 and 4 - they're bundled into the workbook enrollment since they're the graded finals inside those same workbooks. If you want a fully itemized comparison of member vs. nonmember pricing and what drives the cost difference, see the CB Certification Cost 2026: Complete Pricing Breakdown.
| Item | Detail |
|---|---|
| AIPB member self-study total | $479 |
| Nonmember self-study total | $574 |
| Prometric fee (Part 1) | $100 |
| Prometric fee (Part 2) | $100 |
| Failed Prometric retake fee | $60 (after 30 days) |
| Workbook final retake fee | None |
The Six Domains, Ranked by Timed-Test Weight
The CB exam content is organized into six domains, and not all of them carry equal weight when you're sitting under the 2-hour Prometric clock. Based on the structure of the official workbooks, the highest timed-test priority falls on adjusting entries, error correction, payroll, and depreciation - these four topics dominate Parts 1 and 2. Inventory and internal controls/fraud prevention still matter for certification, but they show up more heavily in the open-book, untimed portion.
Domain 1: Mastering Adjusting Entries
Candidates must understand accrual adjustments, deferrals, and how timing differences flow through the trial balance before financial statements are finalized.
- High-value point: practice converting cash-basis transactions into accrual-basis entries quickly, since this appears repeatedly under timed conditions.
Domain 2: Mastering Correction of Accounting Errors
This domain tests your ability to spot transposition errors, one-sided entries, and out-of-balance trial balances, then correct them without disturbing unrelated accounts.
- High-value point: memorize the standard correcting-entry format so you're not reconstructing logic from scratch on every question.
Domain 3: Mastering Payroll
Payroll questions cover gross-to-net calculations, employer tax liabilities, and journal entries for wages, withholdings, and employer contributions.
- High-value point: build a mental checklist of every deduction category so none get skipped mid-calculation on a timed question.
Domain 4: Mastering Depreciation
Expect questions on straight-line, units-of-production, and declining-balance methods, plus how to record disposals and adjust for partial-year assets.
- High-value point: know which method applies by default when a question doesn't specify one - this trips up unprepared candidates.
Domain 5: Mastering Inventory
Inventory costing methods (FIFO, LIFO, weighted average) and their effect on cost of goods sold and ending inventory values are the core focus here.
- High-value point: practice switching between costing methods on the same data set to see how each changes reported profit.
Domain 6: Mastering Internal Controls and Fraud Prevention
This domain covers segregation of duties, authorization controls, and common fraud schemes bookkeepers are expected to recognize.
- High-value point: focus on recognizing control weaknesses in scenario-based questions rather than memorizing textbook definitions.

Eligibility and Experience Recap
Passing all four parts isn't the finish line by itself. Certification also requires agreeing to the AIPB Code of Ethics and documenting experience: at least 2 years of full-time bookkeeping work, or 3,000 hours of part-time or freelance bookkeeping. If you haven't hit that threshold yet, you're not stuck waiting - the experience requirement can be completed within 3 years after you pass the exam parts. This flexibility is one of the more overlooked facts about the credential, and it's worth reading the full breakdown in CB Requirements 2026: Eligibility, Prerequisites & How to Qualify before you assume you're not eligible.
Key Takeaway
You can sit for and pass all four exam parts before your experience hours are finished - just don't let more than 3 years pass between finishing the exam and completing your hours.
Calculator Rules and the Code of Ethics
Prometric has specific equipment rules: only nonprinting, nonprogrammable, self-powered calculators are allowed in the testing room. Bringing a graphing calculator, a phone-based calculator, or anything with printing capability will get flagged at check-in, so verify your device the week before your appointment, not the morning of.
On the ethics side, candidates must formally agree to the AIPB Code of Ethics as part of certification. This isn't a test you study for in the traditional sense, but you should read it closely before you submit your application - it governs your ongoing conduct as a Certified Bookkeeper, not just your exam performance.
Retake Math You Need to Know
Nobody wants to think about failing, but the fee structure is worth knowing upfront. If you fail a Prometric part (Part 1 or Part 2), you can retake it after a mandatory 30-day wait for a $60 fee. That's significantly cheaper than the original $100 Prometric fee, so a retake isn't a financial disaster - it's an inconvenience with a defined cost.
Workbook finals (Parts 3 and 4) work differently: retakes carry no fee at all. Since these are open-book and untimed to begin with, a failed attempt usually points to a gap in understanding rather than exam-day pressure, so use the retake as a genuine study checkpoint rather than a guessing exercise.
One-Week Cram Plan
If you already know the material broadly and just need a final structured review before Prometric day, a short weighted schedule works better than re-reading every workbook page equally. Spend early days on the highest-weighted timed-test domains, then shift to lighter review and open-book domains later in the week.
Adjusting Entries + Error Correction
- Redo every practice problem in these two workbooks from memory, timing yourself against a 2-hour benchmark.
- Flag any correcting-entry format you hesitate on and drill it in isolation.
Payroll + Depreciation
- Rebuild gross-to-net payroll calculations without looking at the answer key first.
- Practice all three depreciation methods on the same asset to compare outcomes quickly.
Inventory + Internal Controls
- Since these lean into the open-book portion, focus on comprehension over memorization.
- Skim scenario-based fraud questions to sharpen pattern recognition.
Full Timed Simulation
- Run a full practice session under real Prometric time limits using our practice test platform.
- Review every missed question by domain, not just by score.
This compressed plan works best as a final review layer, not a first pass at the material. If you're building your study plan from scratch rather than cramming, the CB Study Guide 2026: How to Pass on Your First Attempt lays out a fuller multi-week approach.
CPEC Renewal Cheat Notes
Passing the exam and meeting the experience requirement earns you the designation, but keeping it active is an ongoing obligation. Certified Bookkeepers must complete 60 CPECs (continuing professional education credits) every 3 years to maintain the credential. Treat this like a recurring calendar reminder rather than something to scramble for near the deadline - spreading CPECs across the 3-year cycle is far less stressful than trying to bank 60 credits in the final months.
Key Takeaway
Log CPEC-eligible activities as you complete them rather than reconstructing your history right before a renewal deadline.
Who Actually Hires for This Credential
The CB designation tends to matter most in small-business and outsourced bookkeeping contexts - public accounting firms with bookkeeping divisions, small-business CFO service providers, and companies hiring in-house bookkeepers who want proof of technical competency beyond a resume claim. Because the credential is heavily weighted toward the practical mechanics covered in the six domains above, employers reading a CB line on a resume generally assume solid command of adjusting entries, payroll processing, and error correction without needing to re-test the candidate on fundamentals. If you're weighing whether the credential translates into better job prospects or pay, the CB Salary Guide 2026: Complete Earnings Analysis and Is the CB Certification Worth It? Complete ROI Analysis 2026 both dig into that question in more depth, and CB Jobs covers the kinds of roles that specifically list the credential.
Terminology Quick Hits
If you're brand new to the space or explaining the credential to someone else, a handful of companion pages answer the most basic naming questions in plain language: What Is CB?, CB Meaning, What Does CB Stand For?, What Is A CB?, and What Does CB Mean?.
