Moving into tech, you get hit with confident numbers — pass rates, salary boosts, job guarantees. Most aren’t what they look like, and the site quoting them is often selling the prep. Pick what you saw and we’ll show you how to tell, and what the cited sources actually say. The example claims below are illustrative of patterns we’ve logged — not quotations of any one site.
Pass rates
Is a certification exam pass rate like “70–80%” real?
How to spot it
The tell is source quality, not the shape of the number. A blog estimate, training-provider guarantee, passing score, and personal story can all get repeated online as if they were the same thing: a public candidate pass-rate statistic.
The cited truth
In the current RoleMath pass-rate ledger, reviewed official rows for CompTIA, Cisco, AWS, Microsoft, and ISC2 publish exam facts, passing scores or grades, domains, or scheduling details — not public candidate pass-rate percentages. Third-party numbers stay debunking or recheck context unless the source proves the denominator, method, date, and official provenance.
What RoleMath shows instead
RoleMath never turns a third-party percentage into a pass-rate fact. Instead we publish a source-labeled Difficulty Score where enough official exam evidence exists, and we say pending or source-limited when the evidence is not strong enough.
Does a certification really add a specific amount to your salary?
How to spot it
Watch for an exact per-cert dollar figure with no “compared to what,” and notice the identical “+$15–20K” appearing on unrelated sites with no shared source — a circulated number, not a measured one. Many of these pages sell practice tests for the same cert.
The cited truth
A certification is not a salary. Per-cert “earn $X more” claims typically have no counterfactual (what you would earn without it) and no primary source, and often mix a few real government figures with crowd-sourced numbers to look authoritative.
What RoleMath shows instead
RoleMath shows occupation-level pay from the U.S. Bureau of Labor Statistics and O*NET for the roles a certification maps to — labeled as occupation context for planning, never “this cert pays X.”
Are certification “ROI” and “payback period” claims trustworthy?
How to spot it
An ROI percentage or a “payback in two weeks” needs a salary increase the source cannot honestly know. If there is no cited, counterfactual salary delta, the ROI is built on an invented number.
The cited truth
ROI and payback claims treat an unsourced salary premium as if it were guaranteed and immediate. It is marketing math — and it usually appears on a page selling the prep for that exam.
What RoleMath shows instead
RoleMath shows the real, cited cost of a certification — exam fee, renewal, and materials — with no ROI claim attached. You do the math with honest inputs.
Are bootcamp job-placement rates and guarantees real?
How to spot it
Look for a third-party auditor (like CIRR) and a defined denominator. Often there is neither — and some pages state a high placement rate AND “we do not guarantee placement” on the same site. “Money-back” guarantees are commonly gated behind heavy fine print.
The cited truth
Placement and salary-outcome rates are usually self-reported, with no auditor and no clear “out of how many.” In 2024, U.S. regulators brought public enforcement actions against training providers over inflated or unsupported placement and outcome claims.
What RoleMath shows instead
RoleMath never publishes a placement rate, a job guarantee, or an outcome promise — because none of those can be sourced honestly.
Is a stat like “47,000+ jobs require this certification” sourced?
How to spot it
A precise demand count or “X% of postings require it” should link to a dataset and a date. Often it does not — and the same round numbers recur across affiliate pages.
The cited truth
Precise demand counts and posting-percentages frequently have no traceable dataset, timestamp, or per-stat source. The false precision is the point — it sounds measured.
What RoleMath shows instead
RoleMath won’t publish an unsourced demand count or an “X% of postings” figure. Where we describe employer demand, it stays a small, dated sample of public job-posting language — counts of what employers named, with the sample dated — never an invented percentage.
Is there a single “best certification” to start with?
How to spot it
A universal “best cert” or one fixed ordering ignores your background, budget, and goals — and the page that publishes it often sells the courses in that exact order.
The cited truth
There is no “best cert for everyone.” The right starting point depends on what you already do, what you can spend, and where you want to go.
What RoleMath shows instead
RoleMath does not crown a winner. The planner runs cited data against your situation and shows a personalized path — with the reasoning and the sources.
We hold ourselves to the same line: every pay, outlook, and exam-fact figure on RoleMath traces to an official source, and where the evidence doesn’t support a claim, we say so instead of guessing.
