CAB exam next month – what topics actually show up on the written test?
I've been baking professionally for 11 years, running my own shop for the last 4, and I'm finally sitting for the Certified Artisan Baker exam. I scheduled it for late June and I'm trying to figure out where to focus my remaining prep time. I feel solid on the hands-on components but I'm less confident about the written portion covering food science and regulatory topics.
Specifically, I'm not sure how deep the food science questions go. Are we talking high-level fermentation principles, or does it get into specific enzyme chemistry and water activity calculations? I've been reviewing the RBA study materials but they're pretty dense in places and I'm not sure what's actually tested versus what's background reading.
I've been doing about 90 minutes of written prep a day for the past 5 weeks on top of my normal work schedule. Scores on the practice questions I've found have been around 71-75%, which feels a little low heading into the real thing.
Any advice on what to prioritize in the last 4 weeks would help. Especially curious if the scoring breakdown heavily weights the practical evaluation or if the written portion counts for more than I think.
71-75% on practice tests with 4 weeks to go is fine. I was at 69% with 3 weeks left and passed with a comfortable margin. The real exam questions felt more straightforward in wording than some of the harder practice sets I used.
The food safety and sanitation section caught me off guard. I'd been so focused on baking science that I underprepped HACCP and allergen labeling requirements. Those questions were surprisingly specific on the exam I took.
I passed mine 2 years ago and the written portion counted for roughly 40% of the overall score. The practical evaluation is weighted heavier, so don't let written prep eat into your hands-on practice time. Balance really matters here.
The fermentation science questions go deeper than most people expect. You need to understand preferment ratios, temperature effects on yeast activity, and how hydration levels affect crumb structure. I'd spend at least a week focused just on that section.
I just passed mine in April so hopefully this helps. The written section caught me off guard with how much it focused on fermentation science and gluten development theory rather than just process steps. I'd been doing tons of hands-on practice but hadn't really drilled the "why" behind what I was doing. Honestly the thing that shifted everything for me was running through cab artisan baker artisanal bread pastry crafting 2 the week before because it had questions phrased the way the real test does, which sounds small but it wasn't.
If you're solid on the practical side you're already ahead. Just make sure you can explain hydration ratios, preferment percentages, and what's actually happening during bulk ferment at a conceptual level. That's where I saw the most questions I wasn't expecting.
The written test caught me off guard with how much it focuses on the science behind what we do. Fermentation, gluten development, why certain hydration ratios work -- you can't just memorize answers. When I got a question wrong in practice, I'd actually go figure out why the other option was tempting but incorrect, and that's honestly what saved me. Stuff like understanding why your crust didn't develop the way you wanted tells you way more than just knowing the right baking temp.
For the written portion, I'd pay close attention to scoring, grading standards, and sanitation regs -- it's drier material but it showed up more than I expected. Don't just learn what HACCP is, understand what breaks it and why those failures matter. If you can explain to yourself why a wrong answer is wrong, you're probably ready. That mental habit of questioning the distractors is what'll carry you through.
Honestly the food safety and sanitation section tripped me up way more than I expected. I'd been in kitchens forever and thought I knew it all, but the written test asks about things in really specific ways — like the difference between sanitizing and cleaning, or exact temp ranges for holding doughs. What helped me most wasn't just memorizing right answers but actually figuring out why the wrong ones were wrong. Like if an answer seems right but it's only partially correct, that's usually the trap. I did a bunch of practice on cab/questions/cab artisan baker food safety sanitation 3 and went through every wrong choice asking myself what rule it was violating.
Also don't sleep on the fermentation science questions. It's not just "sourdough needs time," they want you to understand the chemistry behind why. With a month out you've got enough time to go deep on that stuff. Good luck, sounds like you've got the practical side locked down.
Just wanted to share a quick update since I've been following this thread -- I sat a practice run last weekend and pulled a 78, which honestly surprised me because food safety was my weakest area going in. I've been drilling with cab/questions/cab artisan baker food safety sanitation 3 and it actually clicked a lot of the HACCP stuff for me in a way the textbook didn't.
I'm scheduled for mid-July so I've got a few more weeks to tighten things up. If your test is late June you're probably fine on timing -- just don't sleep on the written portion like I almost did. Good luck!
