QEP · EPI · CPEA · CPPS
The Qualified Environmental Professional (QEP) is the Board for Global EHS Credentialing's board certification for environmentalists who solve multi-media problems across air, water, and soil. Unlike a single-discipline license, the QEP is deliberately international in scope — the exam carries no country-specific regulation questions — which is why government agencies, consultancies, and engineering firms treat it as proof of broad scientific judgment. This page covers the full BGC environmental family: the QEP, the entry-level EPI, the CPEA EHS-auditor credential, and the CPPS product-steward credential.

How the QEP is earned — two exams, one credential
125
Part 1: 125 multiple-choice questions (100 scored, 25 pilot) on core science across air, water, and soil. Pass this alone and you earn the entry-level EPI designation.
125
Part 2: 125 questions in one of four specialty areas. Passing both the GES and a specialty exam — with the experience requirements met — earns the full QEP credential.
4
Air Quality, Water Quality, Waste Management, or Environmental Science, Management & Policy — you pick the one matching your practice area.
Each of the two exams is a fixed-form, multiple-choice paper with a seat time of about three hours and no penalty for wrong answers, so it pays to attempt every item. The questions are international in scope by design — they probe scientific principles, calculations, and best practice rather than any single nation's regulations, which trips up candidates who studied only their home country's compliance code.
Scores are scaled against the exam blueprint, and you must clear the GES and your specialty exam to be certified. Your approved application eligibility lasts two years from the end of the month it was approved, and a failed attempt locks you out for 120 days — so candidates who fail one part late in their window can run out of runway and have to re-apply. Planning the sequence around that 120-day wait is half the battle.
QEP, EPI, CPEA, and CPPS — how the Board for Global EHS Credentialing's environmental and EHS credentials fit together
| Credential | Code | Exam(s) | Who it's for |
|---|---|---|---|
| Qualified Environmental Professional | QEP | GES + 1 specialty exam | Experienced environmental professionals (5+ years) |
| Environmental Professional In-Training | EPI | GES exam only | Early-career professionals (under 5 years) |
| Certified Professional EHS Auditor | CPEA | Single EHS auditing exam | EHS and environmental compliance auditors |
| Certified Professional Product Steward | CPPS | Single exam (150 questions) | Product stewardship & lifecycle EHS professionals |
All four are issued by the Board for Global EHS Credentialing (the body that also awards the CIH for industrial hygienists) and delivered through Pearson VUE. The EPI is the natural on-ramp to the QEP: passing the GES once counts toward both, so early-career candidates often earn the EPI first and add the specialty exam later without re-sitting the GES.
Four specialty exams sit on a common GES base — bars show each track's roughly equal share of the QEP specialty pool
Emissions, dispersion modeling, air pollution control, monitoring, and atmospheric chemistry for candidates in air permitting and stationary-source work.
Surface and groundwater, wastewater treatment, hydrology, and aquatic chemistry — the track for water resource and discharge-permit professionals.
Hazardous and solid waste, remediation, site characterization, and waste minimization — built for remediation and waste-handling specialists.
The broad track — environmental management systems, policy, impact assessment, and cross-media science for generalists and program managers.
You only sit one specialty exam, but all four rest on the same General Environmental Science foundation. That is what makes the QEP hard to fake: a single-discipline expert who can model a smokestack plume can still stumble on the cross-media GES content that every QEP must master before touching a specialty.
Two ways to sit a BGC exam — and what to expect on test day
BGC exams are administered at Pearson VUE centers throughout the United States and internationally. Staff verify your government-issued ID, store your belongings, and monitor the room while you work through the multiple-choice paper on a provided workstation. Each exam costs $270, on top of the $160 non-refundable application fee.
When you schedule through Pearson VUE you can choose OnVUE remote proctoring and sit the exam from a private room at home. You download the OnVUE app, run a system test in advance, and complete a live check-in — photo, ID capture, and a 360-degree webcam scan of your room — before the exam unlocks and a proctor monitors the session.
A valid, unexpired government photo ID whose name matches your BGC registration exactly. OnVUE captures a photo of you and your ID before the proctor releases the exam.
A clear desk, no second monitor, no phone within reach, and a full webcam sweep of the room. No notes, no calculator other than the on-screen one, and no one else may enter.
Stay in frame and on-camera throughout the three-hour session. Talking aloud, leaving your seat, or dropping your connection can pause or flag the session, so a reliable setup matters.
The credential that signals broad environmental judgment
Real education and experience gates — then a hard exam
Difficulty: The QEP is hard not because of trick questions but because of breadth. A working specialist in, say, waste remediation must still pass a GES exam spanning atmospheric chemistry, hydrology, toxicology, and policy — material they may not have touched since university. The international framing removes the comfort of memorizing a familiar regulatory code, and the 120-day retest wait means a single weak exam costs months. That's exactly the pressure point our help is built to remove.
The QEP and its siblings put a broad, two-exam science test between you and a credential your employer or agency may already be expecting. Exam Assist pairs you with a vetted environmental-credentialing specialist and works on a pay-after-you-pass model — so the risk sits with us, not you. No upfront fee, guaranteed results: just an honest plan around the GES, your specialty exam, and the OnVUE check-in, with a verified result before you settle.
Tell us which credential you're after (QEP, EPI, CPEA, or CPPS), your specialty track, delivery method (center or OnVUE), and your test window. Takes a couple of minutes over WhatsApp, Telegram, or Discord.
We review your timeline against the two-year eligibility window and the 120-day retest wait and tell you plainly whether it's realistic — before any money is discussed. If it isn't a fit, we say so.
Exam Assist handles the sitting end to end. You're matched with a specialist who maps the work around the cross-media GES content, your chosen specialty blueprint, and the OnVUE environment — discreetly and confidentially.
You only pay once your passing result is confirmed. No verified result, nothing owed.
