To earn the Certified Baker (CB) designation you must be an active RBA member, document four years of full-time experience (or CJB plus three years), verify ServSafe or a 30-hour sanitation course, then pass an online written exam and a one-day practical at 75% or higher. Written preparation centers on the RBA study guide and reading list; practical preparation centers on the site-specific guidebook and formulas sent before your test date.

What the Certified Baker credential verifies

The CB credential verifies professional baking competency through a written and a practical exam, positioned above entry level and below Master Baker.

The Retail Bakers of America (RBA), a trade association founded in 1918, runs a certification program that verifies professional competency through peer-evaluated written and practical exams. Certification is a member benefit, so an active RBA membership is required to apply and must stay active through both exam components.

Certified Baker sits in the middle of RBA's three baking levels, between Certified Journey Baker and Certified Master Baker. RBA describes the CB as a baker who prepares and produces baked goods while assisting with general bakery operations, with enough responsibility to supervise staff and allocate resources.

There are two separate hurdles: an online written test and a one-day practical test, each scored independently. Both must reach 75%.

Eligibility for the CB designation

You qualify with active RBA membership, ServSafe or a 30-hour sanitation course, and four years of full-time experience or CJB plus three years.

Before you can sit either exam, you must meet three qualifying conditions. All are verified from RBA's published criteria on the Levels of Certification page.

First, membership. Certification is available exclusively to RBA members, and the requirement applies from application through the end of testing, so keep your membership current for the whole process.

Second, education. You must verify ServSafe certification or completion of a 30-hour sanitation course offered by a school, government agency or association.

Third, experience. You need a minimum of four years of verifiable full-time commercial or retail baking experience, or Certified Journey Baker certification plus three additional years. Verifiable means documented, so gather employer records early.

  • Active RBA membership (maintained through certification)
  • ServSafe verification or a 30-hour sanitation course
  • Four years of verifiable full-time commercial/retail baking experience, or CJB plus three years

Fees, applications and the two-year window

Budget $25 for the application, $500 for the CB exam fee and $50 for practical site registration, and finish both tests within two years of acceptance.

The application carries a non-refundable $25 fee paid by check, money order or card. Once RBA approves your application and verifies membership, you are charged the exam fee: $500 for Certified Baker. A separate $50 registration fee is due when you book a practical test site.

Timing matters because of a hard rule: approved candidates must complete both the online and performance tests within two years of RBA accepting the application. Miss the window and you lose approved status, must reapply, and forfeit prior fees.

The online exam is delivered through ExamBuilder. RBA schedules it and emails a link with your username and password. You get one click: once you open the link you cannot stop and return, so block out the full allotted time in a quiet space before you start.

The online written exam and how to study for it

Pass a timed multiple-choice online exam across twelve board-approved knowledge domains before you can book the practical; study the RBA guide plus the recommended reading list.

The written exam is a timed, multiple-choice test covering general baking knowledge. Questions come from knowledge domains approved by the Certification Board: ingredients, terms, math, tools, equipment, systems, doughs, merchandising, labeling, nutrition, personnel and management.

For Certified Baker candidates, RBA provides a written exam study guide. RBA frames it as a foundation, not a substitute for broader reading, and pairs it with a recommended list that includes titles such as Professional Baking by Wayne Gisslen, How Baking Works by Paula Figoni and On Food and Cooking by Harold McGee.

You must pass the written exam before taking the practical. RBA states that a candidate who fails the written or practical test in full must wait a year from the second failed test before reapplying. Confirm the applicable retest arrangements with RBA if you do not pass.

RBA confirms that online exams are timed, with the allotted time set for each certification level, but the question count and the exact time amounts are not stated in RBA's retrieved pages. If those specifics matter to your scheduling, ask RBA directly when it arranges your exam link.

The one-day practical exam

Expect a one-day, judge-scored practical at a scheduled test site, scored 75% per segment and overall, with a site-specific guidebook and formulas sent in advance.

CB candidates take a one-day practical test, typically held on a weekend at a school or facility with adequate workstations. RBA uses three to five judges plus a test administrator, and results are given at the test site immediately afterward.

Scoring is segmented: you need 75% on each product segment and 75% for the test overall. Each graded product has a detailed rubric that candidates can review before the exam, and study guides plus recipes are provided.

Your practical study guide is unique to your test site because categories, products and formulas can change by location. You may use RBA's recommended recipes or your own, but if you choose your own recipes, you must notify the RBA Coordinator or a judge at least 30 days before the practical. Candidates will not have access to ingredients outside the provided formulas unless specified before arrival.

Practical exams run several times a year at locations across the country and require a minimum of three candidates. On the schedule published as of September 2026, the March and July 2026 sessions in Chicago and Palm Beach have already passed; the listed upcoming session is February 5-7, 2027 at Johnson & Wales in Charlotte, NC, for CB and CMB candidates. Check RBA's site for the current schedule rather than assuming these dates still stand.

A note on scope: passing a graded practical demonstrates competency under exam conditions, but hands-on production skill is built in your own kitchen. Paper preparation cannot substitute for practice bakes.

  • Review the grading rubric before the exam
  • Study the site-specific practical guidebook and RBA formulas
  • Submit candidate-choice items and extra ingredient lists to the judges 30 days out
  • Connect with your assigned judges beforehand; they accept questions

Worked example: scaling with baker's percentages

In this original scaling exercise, each ingredient is a stated percentage of flour weight. Multiply that percentage by the given flour weight, then add the ingredients.

RBA lists math among the written exam topics, and its practical retest rules also refer to a math/baker’s percentage component. The following original arithmetic exercise defines each ingredient percentage relative to flour weight, with flour set to 100%.

For this exercise, convert the stated percentage to a decimal and multiply by the given flour weight. Add all ingredient weights, including flour, to find the total dough weight.

Practice exercise

Original arithmetic practice: define every ingredient percentage relative to flour weight, with flour as 100%. A formula lists flour 100%, water 62%, salt 2.0% and instant yeast 1.2%. Given 2,500 g of flour, calculate the water, salt and yeast weights and the total dough weight.

Show answer

Water 1,550 g; salt 50 g; yeast 30 g; total dough weight 4,130 g.

Multiply each percentage by the flour weight: water = 0.62 × 2,500 = 1,550 g; salt = 0.02 × 2,500 = 50 g; yeast = 0.012 × 2,500 = 30 g. Total = 2,500 + 1,550 + 50 + 30 = 4,130 g. Two common errors to avoid: reading percentages as shares of total dough rather than of flour, and forgetting that the batch total includes the flour itself.

What happens if you need to retest

The number of failed practical segments determines whether you retest selected items or the entire practical. RBA separately specifies a one-year waiting period from a second whole-test failure.

Retest rules differ by how much you miss. If you fail one or two product segments, you retest only those segments, plus two additional products added so judges can still score time management. The retest fee is $50 per item for CB candidates. You must wait three months, submit documentation of three practice rounds of the product, including emailed pictures of the process and final products, before retesting.

If you fail three or more product segments, you must retake the entire practical exam; the math and baker's percentage portion counts as one of the failed items in that calculation. Retesting happens at a regularly scheduled test, or when judges are available, and off-schedule retests can make you responsible for judge travel and lodging costs routed through RBA.

For whole-test failure, RBA states that the one-year waiting period runs from the date of the second failed written or practical test. Confirm your retest arrangements directly with RBA; this statement does not establish an additional first-failure waiting period.
