Certification comparison
CMGB vs. Governance and Oversight Credentials
The Certified Marketing Governance Board (CMGB) credential doesn't have a single obvious counterpart the way MAI's practitioner credentials do. It's built for a specific kind of role, someone who evaluates governance work critically without necessarily having practiced it themselves, and no other credentialing body has built something that matches that exact shape for marketing specifically. Two established credentials come closest, each matching CMGB on a different dimension. The National Association of Corporate Directors' Directorship Certification (NACD.DC) matches CMGB's subject matter: governance at the top of an organization. ISACA's Certified in the Governance of Enterprise IT (CGEIT) matches CMGB's eligibility model: experience-based oversight competency rather than a board seat. Neither is a clean substitute, and understanding where each one actually lines up is more useful here than picking one and calling it the comparison.
Note: CMGB is a newer credential within MAI's system, and several of its programmatic details, noted below, are still being finalized.
Side by side
| NACD Directorship Certification (NACD.DC) | ISACA CGEIT | Certified Marketing Governance Board (CMGB) | |
|---|---|---|---|
| Governing body | National Association of Corporate Directors | ISACA | Marketing Architecture Institute |
| What it certifies | Board-level governance: fiduciary duty, strategy oversight, risk | Enterprise IT governance: strategic alignment, IT resources, benefits realization, risk optimization | Evaluating architectural reporting, governing architectural investment, and independent oversight judgment for marketing architecture specifically |
| Eligibility | Must currently serve as a director on a public, private, and/or nonprofit board; active NACD membership required | Five or more years in an advisory, management, or oversight role supporting IT governance; no ISACA membership required to sit the exam | No practitioner prerequisite; relevant governance, board, or executive oversight experience evaluated during application review rather than a fixed year requirement |
| Assessment format | Two-part exam: 50 multiple-choice questions in 60 minutes, then 16 case-study questions in 150 minutes, paired with a required foundation course | Single exam, 150 questions across four domains | 40-item written exam across five domains, followed by a scenario-based take-home assessment, followed by a panel assessment; [passing score and time allowed still being finalized] |
| Beyond the exam | Foundation course included in the exam package; no portfolio | None; exam plus application and experience verification | Scenario-based take-home assessment evaluating integrated governance judgment, then a panel assessment evaluating independence and professional conduct directly |
| Cost | $3,995 for the exam package (course and exam); $5,600 bundled with membership | $575 exam fee for members / $760 for non-members, plus a $50 application processing fee | $2,999 |
| Retake policy | Up to three attempts within a two-year window; $250 fee for the second and third | Not published on ISACA's own credentialing or maintenance pages | [still being finalized] |
| Renewal | Every two years: 32 credits, $195 fee | 20 CPE hours annually, 120 total over a three-year cycle, plus a $45 (members) or $85 (non-members) annual maintenance fee due each January 1 | Three-year cycle, consistent with the other MAI credentials; [specific credit count and any fee still being finalized] |
Why two comparisons instead of one
NACD.DC is the closer match on what's actually being governed. Both NACD.DC and CMGB certify oversight judgment at the top of an organization rather than execution within it, and both are built for people who sit in judgment of work other people produce. Where they diverge is eligibility: NACD.DC requires a candidate to currently hold a board seat, a formal governance role. CMGB doesn't. Its handbook evaluates relevant governance, board, or executive oversight experience case by case, without requiring that a candidate already sit on a board.
CGEIT is the closer match on how a candidate qualifies. Its eligibility model, years of relevant advisory or oversight experience rather than a formal board or committee seat, is structurally closer to how CMGB actually admits candidates. What CGEIT doesn't share with CMGB is the subject matter. CGEIT governs IT specifically, not marketing and not governance broadly, and its assessment is a single exam with no take-home component and no panel, considerably lighter than CMGB's three-part structure.
Neither comparison is complete on its own, which is exactly why this page uses both rather than forcing a single winner.
What CMGB actually adds beyond either
CMGB's three-part structure, a 40-item written exam, a scenario-based take-home assessment, and a panel assessment before MAI-trained reviewers, is more elaborate than both alternatives. NACD.DC pairs an exam with a foundation course but no take-home or panel component. CGEIT is exam-only, with a clearly defined but comparatively lighter renewal burden of 20 CPE hours a year against a modest annual fee. CMGB's take-home component specifically evaluates integrated judgment across evidence adequacy, investment conditions, conflicts of interest, and escalation decisions addressed together, and the panel assessment evaluates a candidate's independence and professional conduct directly rather than through written responses alone. That combination, subject-matter specificity to marketing architecture plus a three-part assessment more rigorous than either external benchmark, is the actual differentiator here, more than price or any single structural feature borrowed from one comparison or the other.
Who CMGB is built for
CMGB is explicitly lateral rather than a capstone. It sits alongside the CMAA-CMA-CMAO practitioner ladder, not above CMAO, and it carries no practitioner prerequisite, meaning a board member or executive with governance-relevant experience can pursue it without having held CMAA, CMA, or CMAO first. For many board-level professionals, holding CMGB alongside a practitioner credential like CMA or CMAO is a natural pairing rather than a progression from one to the other, the same way a director might reasonably hold both NACD.DC and a functional governance credential like CGEIT if their oversight responsibilities span both domains.
Frequently Asked Questions
Is CMGB the marketing equivalent of NACD.DC?
Partially. They certify a similar kind of judgment, oversight rather than execution, but NACD.DC requires an active board seat, and CMGB doesn't, so CMGB is reachable by a broader range of oversight professionals than NACD.DC's eligibility bar allows.
Is CMGB the marketing equivalent of CGEIT?
Partially, and for a different reason. CGEIT's experience-based eligibility model is close to CMGB's, but CGEIT governs IT, not marketing, and its assessment is lighter: one exam, no take-home component, no panel review.
Do I need a CMA or CMAO before pursuing CMGB?
No. CMGB carries no practitioner prerequisite. It's a lateral credential, not a rung on the CMAA-CMA-CMAO ladder, so it's open to board members, executives, and oversight professionals without requiring any of MAI's practitioner credentials first.
Can someone hold CMGB alongside a practitioner credential like CMA or CMAO?
Yes, and MAI's own handbook describes this as a natural pairing for many board-level professionals rather than an unusual combination.
