The certification industry runs on numbers with no source: invented pass rates, cert-specific salaries, ROI multiples, placement promises, and precise employer-demand percentages. RoleMath publishes only what it can cite: vendor exam objectives, a transparent stated experience requirement, occupation-level BLS pay, and dated source notes. If a stat has no source you can check, that is the tell.
Key takeaways
- No major IT certification vendor publishes official pass rates, so specific pass-rate percentages online are not primary-source facts.
- A certificate does not have a salary; an occupation does, so RoleMath uses BLS occupation-level pay rather than cert-keyed salary claims.
- Placement and hiring promises need a denominator, an audit trail, and fine-print review before they deserve trust.
- Employer-demand percentages need a dataset, date, query, and track-specific context; otherwise they are false precision.
- There is no single best certification for everyone; the right credential depends on the role, background, budget, and time available.
The quick test: can you trace the number?
A useful certification statistic should answer four questions: who measured it, what population it covers, when it was measured, and where you can verify it. If those answers are missing, treat the number as marketing.
| The stat you will see | Why it does not hold up | What an honest source does |
|---|---|---|
| "An online page gives an 85% exam percentage" | No major IT certification vendor publishes an official pass rate, so the number has no primary source. | Judges difficulty from published exam objectives and a traceable score. |
| "Certification holders earn $15,000-$20,000 more" | A certificate doesn't have a salary - an occupation does. | Publishes dated BLS occupation-level wage context. |
| "Hired in 9 months or your money back" | The denominator and fine print usually matter more than the headline. | Explains how to read outcome claims and makes no placement promise. |
| "X% of postings require this certification" | Precise percentages need a dataset, query, date, and track. | Reports dated, track-specific employer-language signals. |
| "Best cert for beginners" | There is no single best certification for everyone. | Matches the credential to the role, budget, and starting point. |
1. Certification pass-rate claims
What you will see: confident pass-rate numbers attributed to industry consensus, forum chatter, or a provider's own graduates. Why it does not hold up: No major IT certification vendor (CompTIA, Cisco, Microsoft, AWS) publishes an official exam pass rate. Two tells are easy to check: figures for the same exam disagree widely across sites, and a training provider's own graduate result is not the exam-taking population. What RoleMath does: we do not publish a pass rate because we cannot cite one. We judge difficulty from the vendor's published exam objectives, level, recommended experience, prerequisites, format, and exam length.
2. Cert salaries, ROI, and payback claims
What you will see: certification-holder salary lifts, first-year ROI multiples, and payback timelines. Why it does not hold up: a certificate doesn't have a salary - an occupation does. These claims usually lack a primary source, lack a counterfactual, and blur the effect of the credential with the prior experience of the people who earned it. What RoleMath does: we publish occupation-level BLS wage context for the role a credential may support, dated and framed as context rather than a guarantee.
3. Placement promises and outcome claims
What you will see: high placement percentages, fast hired-by timelines, and refund promises. Why it does not hold up: self-reported outcomes can use favorable denominators, exclude hard cases, or define employment too broadly. No honest certification or program can promise a job. What RoleMath does: we run no training program, sell no course, and make no placement promise. We explain how to read outcome claims, ask for the denominator, and keep pay and outlook at the occupation level.
4. Employer-demand percentages
What you will see: exact percentages of postings that supposedly require one credential. Why it does not hold up: Treat precise "X% of postings require Y" stats skeptically unless the page gives the dataset, query, date, geography, role track, and method. Requirement language is track-specific, not universal. What RoleMath does: we treat employer language as a dated skills signal from public postings, never as a universal mandate and never as a personal guarantee.
5. Universal best-cert rankings
What you will see: one ranked list that tells every beginner to follow the same sequence. Why it does not hold up: There is no single best certification for everyone. A retail worker trying to reach help desk, a veteran targeting security, and a support tech moving toward cloud need different steps. What RoleMath does: we start from the target occupation and the person's background, then compare cited difficulty, cost, eligibility, study time, and labor-market context.
Frequently asked questions
Are certification pass rates real?
No major IT certification vendor publishes an official exam pass rate, so any specific pass-rate number online has no primary source. The honest alternative is a transparent stated experience requirement based on published exam facts.
Is a certification pass rate accurate?
There is no accurate certification pass rate to cite when the vendor does not publish one. Numbers online have no primary source and often disagree. Judge difficulty from published exam objectives, recommended experience, format, and a traceable score.
Can an IT certification promise employment?
No. A certification is a signal, not a placement. No honest certification or program can promise a job, so treat hired-by timelines, refund promises, and placement claims as marketing until the denominator and fine print are clear.
Is "X% of jobs require this certification" true?
Treat precise "X% of postings require Y" stats skeptically unless they include a dataset, query, date, geography, and role track. Certification requirements are track-specific, not universal.
How much more do you earn with a certification?
A certificate does not have a salary; an occupation does. Salary-lift claims rarely include a counterfactual. The honest number is occupation-level BLS pay for the role the certification may help you pursue, dated and never guaranteed.
