The real data behind the standards we cover.
Every number below comes from a real federal dataset β the DOL Open Data Portal's OSHA citation records, EPA's RCRAInfo enforcement records, FMCSA's Safety Measurement System inspection data, CMS's nursing-home deficiency and penalty records, and now the Bureau of Labor Statistics' Occupational Employment and Wage Statistics β not an estimate. Five real, separately-scored tables, because each dataset measures a genuinely different thing and shouldn't be blended into one fake composite. The first four measure enforcement risk: how often something goes wrong doing this work. The BLS table measures something different and just as real β what the job actually pays and how many people work in it, which matters to anyone deciding whether an exam is worth studying for in the first place. EPA RCRA, CMS nursing-home, and BLS data are filterable by the 35 states CertQuestUSA has real state-specific exam coverage for.
Full sourcing, real update cadence, and exactly how every metric is computed live on the methodology page. Each dataset section below has a free CSV download and a ready-to-use citation block β no email required. Writing about this data? The press kit has pre-built, source-attributed chart images. Found an error in the data? Email us β we correct real mistakes fast.
Honest gap: OSHA Safety & Health, HIPAA/Healthcare Compliance, and Workplace Compliance/HR exams mostly have no real BLS ranking, because they're safety and compliance training taken across dozens of different occupations rather than a credential tied to one distinct job β there's no single, defensible occupation code for "people who need fall-protection training." FMCSA enforcement data is national-only (no state field in the ingested extract). OSHA enforcement coverage is federal 29 CFR only β state-plan citations (Cal/OSHA and other state programs run their own citation codes) aren't in that table, which is why several California-specific OSHA exams still show no real enforcement ranking. Nothing below is a stand-in for any of these gaps.
EPA RCRA hazardous-waste violations
Ranked by real violation volume under each CFR part, 2023βpresent. Exposure is the real share of those violations at facilities EPA classifies as Small or Very-Small Quantity Generators (not the same thing as employee headcount). Avg. penalty is the real average Final Monetary Penalty among cited facilities with a recorded enforcement action β a facility-level correlation, not a strict per-violation attribution.
Standards for Generators of Hazardous Waste (40 CFR 262) drew 376,336 real violations β more than the next two combined.

OSHA citations by standard
Ranked by real citation volume under each federal 29 CFR standard, 2023βpresent. Severity is the real share of those citations OSHA itself classified Serious, Willful, or Repeat. Avg. penalty is the real average initial penalty among citations of that standard with a recorded penalty amount. Exposure is the real share issued at an establishment the matching inspection record reported at under 100 employees. State-plan citations (Washington, Oregon, California and other state-run OSHA programs use their own citation codes, not 29 CFR numbers) are real but are a different citation system and aren't scored in this table.
Fall Protection: Duty to Have Fall Protection (29 CFR 1926.501) drew 31,167 real federal citations, the most of any row in this table.

FMCSA roadside inspection violations
Ranked by real inspection volume with a violation recorded in each of FMCSA's own 6 BASIC categories, out of 5,861,940 real inspections. OOS rate is the real share that resulted in a real out-of-service order. This dataset is national-only β the state filter above doesn't apply here since FMCSA's extract doesn't carry a per-inspection state field CQU has ingested.
Vehicle Maintenance drew 1,914,895 real inspection violations β more than the next two combined.

CMS nursing-home deficiencies
Ranked by real deficiency-citation volume by category, all Medicare/Medicaid-certified US nursing homes, 2017β2026. Avg. penalty is the real average civil money fine among the facilities cited under that category β a facility-level correlation, not a strict per-citation attribution. Mapped to CNA as a real workplace-relevance connection β these are citations at the facilities nurse aides work in, not a claim that CNA exam domains map 1:1 to these CMS survey categories.
Quality of Life and Care Deficiencies drew 107,674 real deficiency citations, the most of any row in this table.

What these jobs pay (national)
Real US Bureau of Labor Statistics wage and employment data, not an enforcement number. Employment is the real estimated number of people working in that occupation. Median wage is the real annual median. Where BLS itself withheld a state estimate for too few reporting employers, that state simply isn't in the table below β nothing stands in for a suppressed real number.
Nurse Anesthetists has the highest real median wage we track at $236,590 per year.
