What exactly is the Certified Bookkeeper?

AIPB's four-part national bookkeeping credential — the experience-based benchmark for full-charge bookkeepers.

The Certified Bookkeeper (CB) is the national bookkeeping credential from the American Institute of Professional Bookkeepers (AIPB), established as the benchmark for full-charge bookkeepers. It is earned through a four-part exam: two closed-book tests at Prometric — Adjustments & Error Correction and Payroll & Depreciation — plus two open-book workbook finals on Inventory and Internal Controls & Fraud Prevention. Candidates also need about two years of bookkeeping experience (or 3,000 part-time hours) within three years of passing and must agree to the AIPB Code of Ethics. With a 75% pass mark on the Prometric parts and 70% on the workbook finals, the CB signals professional competence in the adjustments and controls that separate a bookkeeper from a data-entry clerk.

The path in brief

1. Confirm you have (or will earn) ~2 years of bookkeeping experience
2. File the paper application and pay the registration fee
3. Wait for AIPB to issue your testing ID number
4. Schedule and pass Prometric Parts 1 & 2 (2 hours each)
5. Complete the open-book Inventory and Internal Controls workbook finals
6. Submit experience proof and sign the Code of Ethics to receive the CB

Before you book

Who is eligible to sit the Certified Bookkeeper?

The CB is open to working bookkeepers without a degree. You may take the exam before finishing the experience requirement, but you must accumulate at least two years of full-time bookkeeping experience (or 3,000 hours of part-time/freelance work) within three years of passing the exam. Undergraduates may count internships and accounting-related volunteer work such as VITA. You apply by mailing a signed paper application to AIPB, which then issues a testing ID number.

Who it is for: Working bookkeepers, full-charge bookkeepers, and accounting assistants seeking a nationally recognized professional designation.

The test itself

What is the format of the Certified Bookkeeper?

The Certified Bookkeeper is administered by American Institute of Professional Bookkeepers (AIPB); Prometric delivers Parts 1–2 and runs 2 hours each for Prometric Parts 1 & 2; Parts 3–4 are untimed open-book finals and requires 75% on Prometric Parts 1 & 2; 70% on workbook Parts 3 & 4 to pass.

The fine print

What are the retake and renewal rules for the Certified Bookkeeper?

Proctoring & delivery

Parts 1 and 2 are closed-book, computerized tests delivered at Prometric Test Centers (300+ U.S. locations) with live center proctoring. Parts 3 and 4 are open-book workbook finals completed at home and submitted to AIPB.

Retake policy

If you fail a Prometric part, you may retake just that test after a 30-day waiting period for a $60 fee (you keep credit for any part you passed). The open-book workbook finals (Parts 3–4) may be retaken at no cost.

Score reporting

Prometric prints your score at the center immediately after Parts 1 and 2. Workbook finals (Parts 3–4) are graded by AIPB after submission; results are reported to you and reflected in your AIPB record.

Recertification

Certified Bookkeepers must complete 60 continuing professional education (CPE) hours every three years, measured from the anniversary of the last certification test passed. CPE must come from AIPB-recognized providers; failure to meet the requirement can result in revocation of the designation.

Refunds & rescheduling

The registration fee is nonrefundable. Prometric test fees are generally nonrefundable once scheduled, though you can cancel or reschedule without penalty if you contact Prometric at least two days before the appointment.

What it pays

How much does this credential pay?

$49,210 median for bookkeeping clerks (BLS, May 2024) — in an occupation BLS projects to shrink 6%

There is no federal wage series for "Certified Bookkeeper," so the honest anchor is the occupational group the CB sits inside: Bookkeeping, Accounting, and Auditing Clerks (SOC 43-3031). BLS puts the median annual wage at $49,210, or $23.66 an hour, in May 2024. The band is real but compressed — the lowest 10 percent earned less than $34,600 and the highest 10 percent more than $72,660 — which tells you something important before you spend a dollar on workbooks: this credential will not, by itself, move you from the middle of that band to the top of it. Now the part most certification pages bury. BLS projects employment in this group to DECLINE 6 percent between 2024 and 2034, a loss of about 94,300 jobs, as bank feeds, OCR receipt capture and cloud ledgers absorb the transaction-entry work that used to fill a bookkeeper's week. That is a genuine headwind and you should price it into your decision. Two things make the picture less bleak than the headline. First, scale: even while shrinking, the occupation still employs roughly 1.6 million people and BLS still projects about 170,000 openings a year, essentially all of them replacement demand from retirements and career changes. Second, composition: the work being automated is not the work the CB tests. Nothing in a bank feed decides whether a December invoice is an accrual or a deferral, reconstructs a botched prior-period entry, determines whether a worker is a contractor or an employee, or designs a segregation-of-duties control that survives an owner who wants to sign his own cheques. The CB is deliberately aimed at that judgment layer — AIPB states plainly that the programme "is not basic bookkeeping" and assumes you are already working or have a year of college accounting. Read the credential, then, as a defensive and differentiating move within a shrinking occupation rather than as a wage escalator: it is evidence that you belong to the part of the profession that survives automation. Industry choice moves the number more than the letters do. BLS reports May 2024 medians of $51,670 in construction, $50,180 in professional, scientific and technical services, and $48,810 in both healthcare and wholesale trade, against $45,030 in retail. AIPB's own member survey data — self-reported and promotional, so weigh it accordingly — claims 59 percent of CBs received a raise after certifying and 48 percent of freelance CBs raised their rates. Treat those as directional marketing figures, not as BLS-grade evidence.

Job growth.Projected -6% decline, 2024-34 (BLS OOH, 2024-34 projections). We are not going to spin this: the occupation is shrinking. The hedge is that the CB certifies adjustment, error-correction, payroll-compliance and internal-control judgment — the work least exposed to automation — and that ~170,000 replacement openings a year still exist.

Your schedule

How long should I study for it?

80-120 hours total, roughly 70% weighted to the four closed-book Prometric tests of focused study

Budget 80-120 hours across the six scored tests, but do not spread them evenly — that is the single most common planning error on this credential. Roughly 70 percent of your hours belong to the four Prometric tests, because those are closed-book, timed at two hours per part, and marked at 75 percent. The two workbook exams are open-book, untimed and marked at 70 percent; they reward knowing where a method lives in the book far more than remembering it. The schedule below assumes 8-10 hours a week and lands in 12-14 weeks. It also assumes you meet AIPB's stated baseline: the CB programme is explicitly "not basic bookkeeping" and expects you to be a working bookkeeper or to have a year of college accounting. If that is not you, add four to six weeks of foundational work before week 1 or the workbooks will read as a wall of unfamiliar notation. Sequence matters more here than on most exams because of how credit and clocks interact. AIPB lets you take the parts in any order and keeps credit test by test, but it also recommends sitting Part 1 before scheduling Part 2 — sensible, because adjusting entries and the adjusted trial balance underpin how depreciation and payroll accruals land in the ledger. Meanwhile the calendar is doing two things at once: you have one year from application processing to complete any one part, and three years to pass everything or start over from zero. So book your first Prometric appointment during week 1, before you feel ready. A date on the calendar is the only reliable defence against the three-year reset. Run the experience requirement in parallel rather than after. AIPB accepts two years of full-time bookkeeping or 3,000 hours part-time/freelance, and — this is widely misreported — the experience may be earned before OR after you pass, with three years from your pass date to document it. If you are already working, you may well have satisfied it before you open a workbook; start collecting the Evidence of Experience signatures early so the certificate is not held up by an ex-employer who takes six weeks to answer email.

1. Weeks 1-4 — Part 1 (both Prometric tests)8-10 hrs/week

   Test 1: accruals, deferrals, unearned revenue, prepaid expenses, unadjusted-to-adjusted trial balance. Test 2: locating errors, the bank reconciliation, correcting current-period accrual and deferral errors

   • Work Mastering Adjusting Entries and Mastering Correction of Accounting Errors, writing quiz answers on separate paper so you can re-do them
   • Drill accrual vs deferral classification cold, with the book shut
   • Automate the out-of-balance divisibility checks (÷2, ÷9) until diagnosis is reflexive
   • Book your Prometric appointment for Part 1 now, not later
2. Weeks 5-8 — Part 2 (both Prometric tests)8-10 hrs/week

   Test 1: employee vs non-employee, federal vs state rules, withholding, deposits, W-4/941/940/W-2/W-3, who gets overtime. Test 2: GAAP depreciation (straight-line, units-of-production, declining balance, sum-of-the-years'-digits) and tax depreciation

   • Work Mastering Payroll and Mastering Depreciation end to end
   • Build one deadline sheet covering deposit frequencies and every form due date, then reproduce it from memory
   • Compute a full depreciation schedule under each GAAP method, then redo it for tax purposes
   • Sit Part 1 at Prometric during this block if not already done
3. Weeks 9-11 — Part 3, Inventory (open-book, at home)6-8 hrs/week

   Perpetual vs periodic recording, weighted and moving average, FIFO, LIFO, and lower of cost or net realisable value (LCNRV)

   • Work Mastering Inventory and tab every cost-flow method for fast lookup
   • Compute FIFO / LIFO / weighted average by hand on the same fact pattern to see the COGS divergence
   • Take the back-of-the-workbook exam — untimed, open-book, no fee, 70% to pass
4. Weeks 12-14 — Part 4, Internal Controls & Fraud (open-book) + close-out6-8 hrs/week

   Employee theft, cheque fraud, credit-card fraud, vendor fraud, computer and internet fraud, and the red flags and dos/don'ts for each

   • Work Mastering Internal Controls and Fraud Prevention and take its back-of-the-workbook exam
   • Sit Part 2 at Prometric
   • Submit the Evidence of Experience form and sign the AIPB Code of Ethics so the certificate is not delayed

What to buy

Which study resources are worth paying for?

The CB has an unusually closed prep market: AIPB writes the workbooks, sets the exam, and hosts the open-book exams in the back of two of those same workbooks, so third-party material is thin and largely unnecessary. The practical decision is not "which publisher" but "self-study or tutored," plus whether the $60 annual membership pays for itself. It does, comfortably, if you are buying the full set — membership costs $60 and saves $35 on registration plus $60 on the workbooks, so it is roughly $35 to the good on the workbook bundle alone before any of the member benefits. The all-in figures are worth stating plainly because they are frequently quoted wrong: registration ($25 member / $60 non-member) plus the two Prometric parts at $100 each plus the six workbooks ($254 member / $314 non-member) comes to $479 for a member and $574 for a non-member. Parts 3 and 4 carry no exam fee at all, and their retakes are free, which is why the total is lower than candidates expect. Budget separately for maintenance: 60 CPECs every three years, registered at $3 per credit. Prices below are AIPB list, checked 2026-08.

What you'll face

What question types will I see?

Everything on the CB is multiple choice — at Prometric you simply select a, b, c or d — but the exam is built from six separately scored tests grouped into four parts, delivered through two entirely different channels, and that shapes how the questions behave. The four Prometric tests (Part 1: Accruals/Deferrals/Adjusted Trial Balance, and Error Correction/Bank Reconciliation; Part 2: Payroll, and Depreciation) are closed-book on a PC, two hours per part, 75% to pass, with an optional tutorial first and your score printed out the moment you finish. AIPB does not publish item counts for them. Because they are closed-book and timed, they test recall and speed of computation as much as understanding: you are expected to know that a difference divisible by nine implicates a transposition or a slide, to remember which form is due 31 January, and to run a declining-balance schedule without looking up the convention. The two remaining tests are printed in the back of the Mastering Inventory and Mastering Internal Controls and Fraud Prevention workbooks, taken at home with the book open, with no time limit and no fee, at 70% to pass. AIPB also offers a paper or online format for these. Their character is different: with the reference in front of you, the questions test whether you can select and apply the correct method — which cost-flow assumption, which control for which fraud scheme — rather than whether you memorised it. Content is stable and published. Part 1 runs from accrual-versus-cash basis through accrued revenue and expenses, unearned revenue, prepaid expenses, other adjustments such as depreciation and bad debt, and the walk from unadjusted trial balance to financial statements; its second test covers where errors occur and how to find them, the bank reconciliation, using the trial balance to find errors, and correcting current-period accrual and deferral errors. Part 2 covers payroll from employee-versus-non-employee classification through federal and state rules, overtime eligibility, deposit timing and the 941/940/W-2/W-3 cycle, then depreciation under GAAP (straight-line, units-of-production, declining balance, sum-of-the-years'-digits) and for tax, including the equipment-versus-buildings and business-versus-personal-use distinctions. Part 3 covers perpetual and periodic inventory, weighted and moving average, FIFO, LIFO and LCNRV. Part 4 covers employee theft, cheque, credit-card, vendor, computer and internet fraud with their red flags. The three samples below are written by our editors against that published outline to show the style and the arithmetic depth; they are not live exam items and never reproduce them.
