TYPES OF CERTIFICATION
(Visite esta página en Español)
The type of certificate you should get depends on the type of lead-related 
construction activities you plan to do. CDPH certification is now required for 
all those doing lead hazard evaluations, lead abatement plan preparation, lead 
abatement work, and lead clearance inspections for residential and public 
buildings in California (Title 17, CCR § 
35001-35050 and § 36000-36100).
Make sure you have completed the required training, experience, and education 
before applying for a Lead Certificate. More information on eligibility and training is provided in the application forms and 
instructions or by calling the Lead-Related Construction Information Line at 
1-800-597-LEAD (1-800-597-5323) (Outside California, dial 510-620-5694.) 
Inspector/Assessor (I/A) Certificate 
The I/A certificate is for those who plan to inspect buildings for lead and 
assess the type of lead hazards in those buildings. This may include:
- Taking paint chip, dust, or soil samples or using an XRF machine to test 
painted surfaces 
- Conducting visual inspections to examine the condition of painted surfaces 
and the location of lead hazards in the building 
- Interpreting laboratory and XRF test results
- Preparing reports on the amount of lead hazards in a building and the risks 
of lead poisoning to the building occupants
- Recommending cost effective ways to safely handle the lead hazards
- Ensuring no lead hazards remain after lead abatement work or other 
construction work where lead is present
Under California's Title 17 
regulations, a certified Inspector/Assessor
Sampling Technician (ST) Certificate 
The ST certificate is for those who, under the direction of an 
Inspector/Assessor, perform sampling activities. This may include: 
- Taking paint-chip, dust or soil samples 
- Using an XRF machine to test painted surfaces 
- Performing visual assessments
Under California's Title 17 
regulations, a certified Sampling Technician
Project Monitor (PM) Certificate 
The PM certificate is for those who plan to oversee lead-related construction 
work to ensure that specifications are followed. This may include:
- Working with consultants, industrial hygienists, journeymen, engineers and 
housing specialists to develop the project specifications
- Performing air monitoring to assess exposure levels and dust wipe sampling 
to ensure adequacy of containment
- Conducting clearance testing at the end of the project to see if any lead 
contamination remains
- Checking work activities for compliance with Federal, State and local 
regulatory requirements
Under California's Title 17 
regulations, a certified Project Monitor
Supervisor Certificate 
The Supervisor certificate is for those who plan to supervise daily work 
activities on a lead-related construction work site and/or prepare lead 
abatement plans. These certificates are also for those who plan to supervise 
repainting or general construction performed on surfaces painted with lead-based 
paint. This may include: 
- Overseeing workers who are performing the activities specified in a lead 
abatement work plans. (Supervisors also perform lead-related construction work 
activities themselves). 
- Enforcing the work practices that ensure worker safety and protect occupants 
from lead poisoning 
- Scheduling and coordinating work site activities with building occupants as 
well as other consultants and contractors 
- Arranging for proper disposal of lead-containing waste created during work 
activities 
Under California's Title 17 
regulations, a certified Supervisor
Worker Certificate 
The Worker certificate is for those who plan to do lead abatement activities 
under the direction of a supervisor. These certificates are also for those who 
plan to do repainting or general construction on surfaces painted with 
lead-based paint. This may include:
 the direction of a supervisor. These certificates are also for those who 
plan to do repainting or general construction on surfaces painted with 
lead-based paint. This may include:
- Building containment structures and sealing off work areas to prevent lead 
dust from spreading 
- Removing, enclosing, or covering lead-based paint hazards or lead-contaminated soil 
- Preparing lead-contaminated waste for disposal and cleaning up the work 
area
Under California's Title 17 
regulations, a certified Worker
Lead Certification Requirements 
The table below shows which types of activities certified lead 
Inspector/Assessors, Sampling Technicians, Project Monitors, Supervisors, and 
Workers may do under California's Work Practice Standards for Lead-Related 
Construction (Title 17, California 
Code of Regulations, Sections 36000 and 36100). Please note that these 
regulations apply only to work done in residential and public buildings. Please 
also refer to the key definitions below for details about what these types of 
activities include:
|  | do lead abatement work? | prepare lead abatement plans? | perform lead hazard 
evaluations? | perform clearance inspections? | 
| Can a certified Inspector/Assessor | no | no | YES | YES | 
| Can a certified  Sampling Technician | no | no | Sampling only | Sampling only | 
| Can a certified Project Monitor | no | YES | no | YES | 
| Can a certified Supervisor | YES | YES | no | no | 
| Can a certified Worker | YES | no | no | no | 
    
Key Definitions
The following definitions are provided for guidance only. They do not contain 
exact language from California's lead work practice 
standards.
- Abatement - Any 
set of measures designed to reduce or eliminate lead hazards or lead-based paint 
from residential or public buildings. Abatement does not include containment or 
cleaning activities. 
- Clearance Inspection - An on-site limited investigation, performed according to 
U.S. Department of Housing & Urban Development (HUD)guidelines, to determine if 
lead hazard control work has been completed as specified and if the work area is 
safe for unprotected workers, residents, and children to enter.  Does not 
include personal air monitoring activities done to ensure Cal/OSHA compliance, 
representative sampling of components removed from a building to determine the 
applicability of hazardous waste requirements, or sampling done to determine 
adequacy of containment. 
- Lead Hazard Evaluation - An on-site inspection, risk 
assessment and/or clearance inspection, done for pay or other compensation, to 
determine the presence or amount of lead-based paint or lead hazards in a 
residential or public building. Does not include personal air 
monitoring activities done to ensure Cal/OSHA compliance, representative 
sampling of components removed from a building to determine the applicability of 
hazardous waste requirements, or sampling done to determine adequacy of 
containment. 
- Lead Hazards - 
Deteriorated lead-based paint, lead-contaminated dust, lead-contaminated soil, 
lead-based paint that is disturbed without containment or any other nuisance 
which results in persistent measurable lead exposure. Lead hazards include all 
paint or surface coatings on residential or public buildings built before 
January 1, 1978, that are disturbed without containment. (Such surface coatings 
are presumed to contain lead.)
