- CC exams are administered through Kryterion testing centers, not on fixed calendar "windows" published by ABCC.
- Since February 2026, both parts are delivered in person with no prescheduled breaks - plan your day accordingly.
- You have a three-year eligibility period to pass both Part A and Part B once approved.
- Each part can be attempted a maximum of two times, so scheduling mistakes are costly.
How CC Exam Scheduling Actually Works
Unlike credentialing programs that publish a handful of fixed testing weeks each year, the Board Certification in Clinical Chemistry exam is delivered through Kryterion testing centers under the American Board of Clinical Chemistry (ABCC). That means scheduling is candidate-driven: once your application is approved and your eligibility period opens, you work with Kryterion to select a testing center and a date that fits your availability rather than waiting for an announced "window."
This flexibility is helpful, but it also puts more responsibility on you to plan ahead. If you're still mapping out what the exam actually covers before you think about dates, start with the CC Exam Domains 2026: Complete Guide to All 7 Content Areas so you know how much runway you'll need before you lock in a testing date.
The 2026 Format Change: In-Person Testing
A significant scheduling variable for 2026 candidates: since February 2026, the CC exam has been delivered in person at Kryterion testing centers, with no prescheduled breaks during either part. This is a meaningful shift for anyone planning their test day logistics.
- Part A - Calculations and Problem Solving - runs three hours for 30 five-option multiple-choice questions.
- Part B - Analytical and Clinical Issues - runs three and one-half hours for 140 questions.
With no built-in breaks, candidates need to plan their own pacing and stamina strategy, particularly for the longer Part B session. If you're unsure how demanding this really is compared to what you've heard about other certifications, the breakdown in How Hard Is the CC Exam? Complete Difficulty Guide 2026 is worth reading before you commit to a date.
Key Takeaway
Schedule your test date on a day when you can arrive well-rested and are not sandwiched between other obligations - there's no built-in break to recover mid-exam, especially during the 3.5-hour Part B session.
Application Timeline and the Three-Year Eligibility Window
Before you can pick a testing date at all, your application has to clear ABCC's eligibility review. Standard eligibility requires:
- An accepted doctoral degree
- At least 30 semester hours of qualifying coursework
- Five years of postdoctoral professional experience in an approved clinical-laboratory setting
- Three references
Accredited-fellowship and alternate-board pathways can shorten the experience requirement, so it's worth checking your specific situation against the full breakdown in CC Requirements 2026: Eligibility, Prerequisites & How to Qualify before you submit anything.
Once you're approved, the clock starts on a three-year eligibility period during which you must pass both Part A and Part B. This is the single most important date-related fact for planning purposes: everything else - when you sit for Part A, when you retake a failed part, when you attempt Part B - has to fit inside that three-year window.
Scheduling Part A and Part B Separately
Part A and Part B are distinct exams with different lengths, question counts, and content focus, and they don't have to be scheduled back-to-back. Many candidates choose to sit for one part, review performance, and then schedule the second part once they've reinforced weaker areas.
| Detail | Part A: Calculations and Problem Solving | Part B: Analytical and Clinical Issues |
|---|---|---|
| Question count | 30 questions | 140 questions |
| Time allotted | 3 hours | 3.5 hours |
| Fee | $200 | $200 |
| Share of total question volume | 30 of 170 | 140 of 170 |
Because Part B carries the overwhelming majority of the total question volume, many candidates schedule extra preparation time before that sitting specifically. For a side-by-side look at how these two parts differ in scope and what that means for your study plan, see CC Study Guide 2026: How to Pass on Your First Attempt.
Matching Domain Prep to Your Testing Date
The exam is built around seven official knowledge areas that provide the content framework spanning both parts. When you're deciding how far out to schedule your test date, it helps to know which domains typically demand the longest lead time:
Domain 3: Analytical, Instrumentation, and Methodology
Candidates must understand instrument principles, method validation, and analytical troubleshooting well enough to apply them to scenario-based questions, not just recall definitions.
- Method comparison and validation concepts
- Instrument-specific analytical principles
Domain 4: Statistical Analysis and Mathematics
This domain overlaps heavily with Part A's calculation-heavy format, so candidates scheduling Part A soon should prioritize timed practice with formulas and unit conversions.
- Dilution and concentration calculations
- Statistical quality-control interpretation
The other five domains - Clinical Chemistry Interpretation and Problem Solving, Clinical Case Approach, Toxicology, Regulatory/Management/Quality Assurance, and Molecular and Genetics - round out Part B's broader clinical and applied focus. A full domain-by-domain breakdown, including how each area tends to show up in question phrasing, is available in the CC Exam Domains 2026: Complete Guide to All 7 Content Areas.
Fees, Deadlines, and What You're Paying For
Every scheduling decision has a cost attached, and the fee structure is straightforward but nonrefundable at the application stage:
- Application fee: $500, nonrefundable
- Each exam part: $200
- Total if both parts are taken: $900
Because the application fee is nonrefundable, it pays to be genuinely ready to begin your three-year eligibility clock before you submit - rescheduling a testing date with Kryterion is one thing, but restarting the application process is a much bigger setback. For the complete cost picture, including how these fees compare across the full path to certification, see CC Certification Cost 2026: Complete Pricing Breakdown.
Key Takeaway
Treat the $500 application fee as your commitment point - submit it only when you're confident you can realistically prepare for and schedule Part A and Part B within the three-year window.
Retake Rules and Scheduling a Second Attempt
Each part of the CC exam may be attempted no more than twice, and both attempts must still fall within your three-year eligibility period. This has direct scheduling implications: if you fail Part A on your first attempt, you can't wait indefinitely to retake it - you need to schedule your second attempt with enough buffer left to also complete Part B (or its own retake) before the window closes.
Understanding how the published average cumulative five-year pass rates (53% for Part A and 55% for Part B) play into retake planning can help you set realistic expectations rather than assuming a first-attempt pass is guaranteed. The full data discussion is in CC Pass Rate 2026: What the Data Shows, and if you want to know precisely what score you're aiming for, check CC Passing Score 2026: Exactly What You Need to Pass.
Building a Study Timeline Around Your Test Date
Once you have a testing date locked with Kryterion, work backward to structure your remaining preparation weeks around the two parts' distinct demands.
Foundation on Domains 3 & 4
- Review analytical/instrumentation principles and calculation-heavy problems that dominate Part A
- Time yourself on practice calculations to build speed for the 3-hour limit
Broaden into Part B's clinical domains
- Work through Clinical Case Approach and Clinical Chemistry Interpretation scenarios
- Layer in Toxicology and Molecular and Genetics content
Full-length practice under test-day conditions
- Simulate the no-break, in-person format so pacing feels familiar
- Run full practice sets on our practice test platform to gauge readiness across all seven domains
This kind of structured runway matters more for CC than for exams with lighter content frameworks - with 140 questions concentrated in Part B, uneven pacing on test day can leave strong candidates short on time. If you want a compressed reference to run through in your final week, the CC Cheat Sheet 2026: One-Page Review of Must-Know Facts is designed for exactly that purpose.
After You Pass: DABCC Renewal Timing
Passing both parts isn't the end of the scheduling story. Maintaining active DABCC status requires 50 continuing-education contact hours and a $350 renewal fee every two years. Mark this recurring deadline on your calendar the moment you're certified - lapses in CE tracking are far easier to prevent than to fix retroactively.

Frequently Asked Questions
No. The exam is administered through Kryterion testing centers on a rolling basis rather than fixed annual windows, so your testing date is scheduled individually once your application is approved.
Once your eligibility period opens, you have three years to pass both Part A and Part B, with a maximum of two attempts allowed per part.
Since February 2026, the exam has been delivered in person at Kryterion centers with no prescheduled breaks during either Part A or Part B, so plan your pacing and stamina accordingly.
The two parts have separate time allotments (3 hours for Part A, 3.5 hours for Part B) and separate $200 fees, and candidates often schedule them on different dates to allow focused preparation between sittings.
Each part can be attempted no more than twice within the three-year eligibility period; exceeding that limit without passing means you would need to restart the application and eligibility process.
