Weighing an offer for this job?
Where it falls among certified offers, and the four wage levels DOL sets for it by area.
Too few cases for a rate
2 decided filings: too few for an approval rate.
Why
Across every PERM case DOL decided in this window, 3.20% were denied. At that rate a file this size comes back clean most of the time whatever the occupation did, so a percentage would be a fact about how few cases there are. Telling a clean record apart from the field takes about 117 decided cases.

How these figures fit together
BLS surveys employers on what they pay everyone in a job; DOL builds its four levels from the same survey a year later (the July 2026 wage year uses BLS's May 2025 estimates). DOL publishes levels by area, not nationally, so the United States line has none. Levels are hourly in DOL's tables; here they're shown a year at 2,080 hours, as DOL computes them. The metros are the ones holding the most of this job's PERM filings, placed by Census's county files.
The block is the middle half of what employers report paying everyone in this job, citizen or not; the ticks under it are DOL's four prevailing wage levels for that metro, the floors a PERM or H-1B offer is held to. More

The same job on H-1B
2,434 certified H-1B labor condition applications for this occupation since FY2020, offering a median of $78,000 a year; the middle half ran $65,000 to $98,242. By state and year in the salary explorer.
Notes on these numbers
Reading the wage
A floor, not a salary survey: every level and metro mixed. DOL's four wage levels for this job, by area.
What the median is
The median wage employers committed to in federal filings for this occupation. It mixes every experience level and every metro, and it's a floor: the employer must offer at least the prevailing wage DOL determines for the occupation, level and county. Across all PERM filings the middle half of offered wages runs $45,178 to $141,357, so a figure inside that band is unremarkable whichever occupation it belongs to. The levels page reads DOL's OFLC wage search live.
What these numbers don't say
4 notes
- The code is the identity
- This one is SOC 19-2041.03. Two SOC codes can carry the same job title, so a title that looks duplicated on the ranking is two different occupations. Match on the code when you're checking a specific filing.
- A median isn’t an offer
- It's the middle of all 2 wages committed to for this occupation across the country, entry level and principal alike. The same role's medians swing hard by worksite, which the state map shows directly.
- Approval isn’t about the occupation
- The denial rate moves with what happened in the filing rather than with the job title, so nothing here is a property of Industrial Ecologists. The measured factors are on the denial risk page, published as separate rates.
- Nothing here is pending
- All 2 counted here carry a decision date, because every case in DOL's disclosure files does, so a case still waiting is in none of them. Where the queue stands today is on the processing times page.
The window these figures cover: DOL's PERM disclosure files for fiscal years 2024 to 2026, through the third quarter of 2026, 373,939 decided cases. Nothing pending is counted here. How each figure is built
Weighing an offer?
Compare it against this median, then check the state map, where the same occupation's medians swing hard by worksite.
Setting one?
All 1,410 occupations sort together on the wages page, and denial rates show how outcome moves with the offered wage.
Filings newer than DOL's last published file can't be attributed to this occupation until DOL publishes them. The live list on the case search page carries them by employer.
