Licensing authority: California Department of Public Health, Childhood Lead Poisoning Prevention Branch · Application information

Reapplication for examination permission after an unsuccessful 180 day permission period
Lead Abatement Supervisor Certification Examination
Application
Comply with § 35095, except § 35095(a)(3)(B), (a)(3)(C), (a)(3)(D) and (a)(4), as expressly exempted by § 35096(c)(1).
Attempt limit
§ 35096(c)(2) permits no more than three attempts within 180 days of the permission notice.
Certification
Pass the Supervisor certification examination; CDPH grants or denies certification under § 35096(c).
Eligibility
Previously received permission for the Supervisor examination but did not pass within 180 days of that notice.
Training
Retake the CDPH-approved lead-related construction course in the Supervisor discipline under § 35096(c)(1).
Initial certification with certified lead worker experience
Lead Abatement Supervisor Certification Examination
Application
Submit the CDPH application, identification and personal information, required documentation, photograph and non-refundable $135 certification fee. 17 CCR § 35095(a)(4) specifies two 1-inch photos; CDPH 8488 (7/20) offers a recent photo print of at least two inches square or an emailed digital JPEG of at least 640 x 480 pixels.
Certificate duration
Certification is non-transferable and effective for one year under 17 CCR § 35096(f).
Department review
Under 17 CCR § 35096(e), CDPH may consider eligibility, training, further documentation, prior citations or violations, prior revocation, and false or misleading application statements.
Education
No education requirement for Supervisor certification (CDPH 8488, Supervisor Certificate Requirements).
Exam timing
17 CCR § 35096(b)-(c) sets permission to sit before certification, a 180-day permission period and at most three attempts within that period. CDPH's implementing FAQ instead states: "You may take the exam at any time. However, you need to pass the exam before you apply to CDPH for certification." Submit the CPS passing-results letter with the application, as the FAQ and CDPH 8488 direct.
Experience
Have one year of experience as a certified lead worker under 17 CCR § 35085(b)(1).
Experience documentation
Provide CDPH 8539 Proof of Experience forms. CDPH 8488 permits a current and active California CSLB contractor license in the applicant's name in classifications A, B, C-4, C-12, C-15, C-17, C-21, C-32, C-33, C-34, C-35, C-39, C-43, C-47, C-61/D-38, C-61/D-63, ASB, or HAZ as proof of experience; this is a documentation alternative, not a separate examination or exemption. The explanatory instruction pages print C-3 while the application itself prints C-43; the application list is recorded here.
Retake instructions
The regulatory limits in 17 CCR § 35096(c) apply. The study guide additionally states: "You may take the exam as many times as you need to in order to pass." The FAQ says there is no waiting period to retake an exam, but each repeat requires registration and payment.
Training
Complete a CDPH-approved 40-hour Supervision and Project Monitoring course, or a 24-hour Work course plus a 16-hour Supplemental Supervision and Project Monitoring course; supply Course Completion Form CDPH 8493. Course-end testing and hands-on course work are training conditions.
Training recency
17 CCR § 35082 requires application within one year of the course completion form; after one year complete at least seven hours of general continuing education or continuing education for workers; after three years retake the approved initial course. CDPH online instructions also require initial training again when refresher training has not been completed within 24 months of prior training.
