““Clear questions that strengthened my data analytics knowledge.””

Business Analyst
The IIBA-CBDA doesn't certify that you can run a regression or write a clean SQL query. It certifies that you can take a vague business ask, turn it into an answerable question, get the right data behind it, and then walk a skeptical stakeholder through what the numbers actually mean. IIBA built the exam around six domains that follow that lifecycle end to end, and it's explicitly vendor-neutral — Power BI, Tableau, and SQL show up in scenario language, but you're never tested on a specific menu path or function.
That distinction matters because CBDA sits in an unusual spot: it's not a data-science credential and it's not a generic BI-tool certificate. It's a business analysis credential that happens to be about analytics, which is why the domains most candidates underestimate — interpreting results and influencing decisions — carry as much weight as the technical analysis domain.
There's no mandatory eligibility requirement, but IIBA recommends 2–3 years of experience in business analysis or data analytics before attempting it. In practice, two very different groups sit this exam: business analysts who are strong on stakeholder work but light on hands-on data analysis, and data analysts who are comfortable with the numbers but haven't had to defend a recommendation to an executive. Neither group has an obvious edge — the exam is built to test the seam between those two skill sets, not just one side of it.
It's a poor fit for someone starting from zero in both business analysis and analytics, and it's not the right credential if what you actually want is a technical, tool-specific certification (Microsoft's PL-300 or a Tableau credential would serve that goal better).
Seventy-five multiple-choice questions in 120 minutes works out to about 96 seconds per question — but the constraint isn't arithmetic speed, it's reading speed. Each question opens with a short business scenario, and the four answer options are usually all technically defensible; the one that's correct is the one that fits the specific situation described, not the most sophisticated-sounding technique. The exam is delivered entirely online through remote proctoring, so you'll need a private room, valid photo ID, and a stable webcam/microphone setup that meets IIBA's remote-exam requirements before test day.
IIBA doesn't publish a flat passing percentage. Scoring uses a scaled, psychometric cut-score method, and your result comes back as pass/fail along with a domain-by-domain performance breakdown — which means a strong showing in one domain can't fully offset a weak one spread across all six.
The blueprint follows the Guide to Business Data Analytics, IIBA's companion reference (members-only access). These are the current official weights:
Domain | Weight | Approx. Questions |
|---|---|---|
Identify the Research Questions | 20% | 15 |
Source Data | 15% | 11 |
Analyze Data | 16% | 12 |
Interpret and Report Results | 20% | 15 |
Use Results to Influence Business Decision-Making | 20% | 15 |
Guide Organization-Level Strategy for Business Analytics | 9% | 7 |
Domain 6 is the one candidates most often shortchange in self-study, because it feels the least hands-on — it covers analytics maturity and governance at an organizational level rather than a project level. With only 7 questions tied to it, missing several is a bigger proportional hit than the 9% label suggests.
There's no separate application fee for CBDA. The exam fee itself depends on membership status:
Fee Type | IIBA Members | Non-Members |
|---|---|---|
Exam Fee | $250 (includes first year of IIBA membership) | $405 |
Retake (Rewrite) Fee | $195 | $350 |
Recertification Fee (annual) | $30 | $50 |
Because the member exam fee already includes a first year of membership, paying $250 as a new candidate is usually cheaper overall than paying the $405 non-member rate outright — and it also drops your future retake fee if you need one. Prices are set in USD and subject to change without notice.
There's no application review, no required coursework, and no formal eligibility gate — anyone can register. The 2–3 years of recommended experience is guidance, not a checkpoint IIBA verifies before you're allowed to sit the exam.
Because IIBA won't publish a target percentage, most exam-prep providers estimate somewhere in the 65–70% range based on candidate reports — but treat that as an informed estimate, not an official number. What is confirmed is that you get a pass/fail result plus a breakdown across all six domains, which is useful for retake planning even though it doesn't tell you your raw score.
This is where CBDA differs sharply from IIBA's core certifications, and it's a detail a lot of candidates miss until it's too late: CBDA is not a lifetime credential. It expires one year after you pass, and to keep it active you need to earn 20 Continuing Development Units (CDUs) during that year — with a minimum of 10 CDUs coming from each of two required activity streams — and pay the $30 (member) or $50 (non-member) recertification fee. There's a four-month grace period after your certification date if you fall behind, and up to 5 excess CDUs can roll into your next cycle. Compare that to CBAP or CCBA, which recertify every three years with 60 CDUs; CBDA's annual cycle is much tighter.
The closest direct competitor is the Certified Analytics Professional (CAP) from INFORMS, which also sits in the "business-facing analytics" space rather than pure data science — but CAP leans more heavily on quantitative methods and requires documented analytics experience or education to even apply, where CBDA has no such gate. For someone choosing between the two, CBDA is the better fit if your background is business analysis first and analytics second; CAP suits someone already doing applied analytics work who wants a credential that leans more technical. Google's Data Analytics Professional Certificate is a different category entirely — an entry-level training program with no exam gate, aimed at people breaking into analytics from scratch rather than validating existing BA experience.

Because the six domains function as a connected cycle rather than six standalone topics — sourcing constraints often force you to reframe the original research question, for instance — a 5–6 week study plan structured around the Guide to Business Data Analytics tends to work better than cramming domain by domain in isolation. Candidates with solid BA experience but limited hands-on data work often need to spend extra time specifically on Domains 2 and 3 (sourcing and analysis); the reverse is true for data-heavy candidates who are light on stakeholder-facing domains 1, 4, and 5.
