1.1 Current Exam Facts

Why this credential exists

Quick Answer: An EPA certified supervisor completes a minimum 32-hour accredited course (8 hours hands-on), then applies for individual certification and passes EPA's third-party exam ($70 per attempt). EPA does not publish that exam's question count or passing score. Individual supervisor certification is $410; the firm must also be certified ($550 every 3 years). Course completion is only 6-month interim certification.

Congress created this program in Title X of the Housing and Community Development Act of 1992 (the Residential Lead-Based Paint Hazard Reduction Act). Title X directed EPA, under TSCA section 402 (15 U.S.C. 2682), to write training, certification, and work-practice rules for people who inspect, assess, and permanently eliminate lead-based paint hazards. Those rules are 40 CFR 745 Subpart L. They apply to target housing and child-occupied facilities in states and Indian country that do not have an EPA-authorized program under Subpart Q (40 CFR 745.220). In an authorized state, you follow that state's equivalent program—which must be at least as protective as EPA's and may use a state exam instead of EPA's third-party exam.

This is not the 8-hour RRP renovator card (Subpart E). RRP covers renovation, repair, and painting that is not designed as abatement. The supervisor discipline is for abatement: measures designed to permanently eliminate lead-based paint hazards (for dust-lead, to below the action levels). A certified supervisor is the individual trained and certified to supervise and conduct abatements and to prepare occupant protection plans and abatement reports (40 CFR 745.223).

Subpart L generally does not apply to a person doing lead-based paint activities inside a dwelling they own, unless someone other than the owner or the owner's immediate family occupies it while the work is done, or a child in the building has been identified as having an elevated blood lead level (40 CFR 745.220(b)). Federal agencies and their contractors on federal property are still subject to these rules (745.220(c)).

Training, individual certification, and firm certification are three different things

Exam items fail people who treat a class certificate as an EPA credential, or who show up as a certified individual working for an uncertified company. Keep the layers separate:

1. Accredited training. Complete a supervisor course from an EPA-accredited (or authorized-state-accredited) training program. The provider must give a course test and a hands-on skills assessment, or a proficiency test in their place (40 CFR 745.225(c)(7)). Passing that test proves you passed that class. It is not EPA certification.
2. Individual EPA certification. For inspector, risk assessor, and supervisor, you must also pass EPA's third-party certification exam and show you meet the experience rules (40 CFR 745.226(b)). Workers and project designers do not take that exam.
3. Firm certification. After March 1, 2000, every firm that performs or offers to perform lead-based paint activities must be EPA-certified and may employ only appropriately certified people (40 CFR 745.226(f)). A certified supervisor on an uncertified firm's letterhead is still a TSCA problem.

Worked example. Maria finishes Friday's accredited supervisor course, scores 92% on the provider test, and passes the hands-on assessment. Monday a property manager asks if she is "EPA certified" to run a window-sash replacement abatement. She has a course completion certificate that is interim certification for 6 months and she may begin work under that interim status, but she is not EPA-certified until she applies, sits the third-party exam, and receives EPA's certificate. The firm still needs its own certification. If she waits until month 5 to apply, she can run out of calendar to test and then must retake the entire initial course.

Hours: 32 classroom-equivalent hours, 8 hands-on—not 40

The accredited supervisor course shall last a minimum of 32 training hours, with a minimum of 8 hours devoted to hands-on activities (40 CFR 745.225(c)(6)(iii)). A training hour is at least 50 minutes of actual learning—lecture, activities, demonstrations, evaluations, or hands-on—not a 60-minute clock hour padded with breaks (40 CFR 745.223).

Vendors and older study sheets still say 40 hours. That number is a trap. EPA's current supervisor minimum is 32/8. A provider may teach a longer class, but the regulation you must quote is 32 hours with 8 hands-on. For comparison, worker is 16/8, inspector is 24/8, risk assessor is 16/4 (after inspector), and project designer is 8 hours with no hands-on minimum in 745.225(c)(6)(iv).

Hands-on for the supervisor course must include curriculum items (v), (vii), (viii), (ix), and (x) of 40 CFR 745.225(d)(3):

• (v) Risk assessment and inspection report interpretation
• (vii) Lead-based paint hazard recognition and control
• (viii) Abatement and hazard-reduction methods, including restricted practices
• (ix) Interior dust abatement and cleanup
• (x) Soil and exterior dust abatement

The other required topics—role, health effects, federal/state/local rules, liability and insurance, occupant protection plan and abatement report, action levels and testing, cleanup and waste, recordkeeping—are still mandatory course content. They are simply not the listed hands-on set.

Two tests, one of them unpublished

In an EPA-administered jurisdiction you sit two different evaluations. Mixing them is the most common format trap on this exam.

Do not use a 100-item practice bank as the real exam size. Do not invent a 70% or 80% cut score. Accredited-provider course tests vary. Some authorized states run their own certification exam instead of EPA's; passing EPA's exam does not automatically license you there.

Logistics table: hours, fees, interim, recertification

EPA advises submitting the certification application within 30 days of training so there is calendar left to schedule the third-party exam before interim status expires. Recertification mechanics and firm-cycle enforcement are Chapter 2 topics; for this chapter, remember that both the individual and the firm must be certified before you run a job.

On or after January 12, 2026, post-abatement dust-lead action levels are 5 µg/ft² on floors, 40 µg/ft² on interior window sills, and 100 µg/ft² on window troughs (40 CFR 745.227(e)(8)(viii)). Those numbers, the separate "any reportable level" dust-lead hazard definition, and the mandatory hazard statement in the abatement report are taught in later chapters—especially Chapter 18. For exam logistics, know that 5/40/100 is current law and that clearance sampling is not a supervisor task.

How to use this guide against the two-test structure

1. Memorize this chapter's numbers: 32/8 hours, $70 exam, $410 individual, 6-month interim, 3 attempts, experience prereqs, and the on-site / 2-hour rule in the next section.
2. On every scenario, name which layer is missing: course only, individual cert only, or firm cert only.
3. Work the remaining chapters through the 13 supervisor curriculum topics in 40 CFR 745.225(d)(3), plus OSHA 1926.62 and RCRA waste. Those topics are how you pass the third-party exam.
4. Treat practice questions as concept checks. They are not a photocopy of an unpublished EPA form.
