Who must take the certification exams?

California requires certification exams for Lead Inspector/Assessors, Lead Supervisors, and Lead Project Monitors. There are separate exams for each of these three types of certificates. Lead Workers and Sampling Technicians are not required to take a certification exam, however, they are still required to apply to CDPH for certification - see the Applying for Certification page for more information.

Who offers the certification exams?

CPS HR is the contractor that CDPH has chosen to administer the exams. This company has extensive experience administering many types of licensing and certification exams in California. This is the only company authorized to offer California's approved lead certification exams. Passing a certification exam offered by another company or another state will not make you eligible for lead certification in California.

Where and when are the exams offered?

 CPS HR offers the exams quarterly at testing sites alternating between Northern and Southern California.

What are the exams like?

The certification exams consist of 100 to 125 multiple-choice questions. All of the exams are offered in English and do not include any "hands-on" or performance testing.

Can I take the exams in Spanish?

The Supervisor exam is offered in Spanish. The exam is equivalent to the English language version, and all of the costs and procedures are the same. The Supervisor study guide is also available in Spanish, at the bottom of this page. Note: you can take the exam in Spanish even if you took the training in English. No other exams are available in languages other than English.

How much does it cost to take the exams?

Temporarily, there will not be a fee to take the state Lead-Related Construction exams.

Are special accommodations available for people with disabilities?

Yes, for no additional charge, CPS Human Resource Services can provide ADA accommodations for those with special needs.

Are there "combined" exams?

No. The exams for Lead Inspector/Assessor, Lead Supervisor, and Lead Project Monitor are each separate. If you want to get more than one of these certificates, you must take a separate exam for each. You can take up to two exams per day.

When do I take my exam?

You may take the exam at any time. However, you need to pass the exam before you apply to CDPH for certification.

How do I register for my exam?

You may telephone CPS Human Resource Services directly at (916) 263-3624, option 5, to obtain registration materials. You can also get information on the CPS HR website. Complete the registration form that you received from CPS HR and mail it to:

Attention: Lead Certification Registration
241 Lathrop Way
Sacramento, California 95815

You must register for your exam at least two weeks before the exam date. Do not send your exam registration form to CDPH.

How do I get admitted into the exam?

To be admitted into your exam, you must show a government photo ID, such as a State Driver's License, State ID Card, Passport, Military ID Card, or Resident Alien Card. If you cannot properly identify yourself when you arrive to take your exam, CPS HR will turn you away and not allow you to take the exam. You may reschedule the exam should this happen.

How do I reschedule an exam?

Candidates wishing to reschedule or withdraw after an exam must notify CPS HR in writing within 5 business days of the exam.

What happens if I fail my exam?

If you fail an exam, CPS HR will tell you how many questions you got correct and how many you missed on each of the topic area subsections of the exam. For exam security reasons, however, they cannot tell you which questions you missed. You may retake the exam, following the same procedures as the first time. There is no waiting period, however, you should take the time to study more before retaking the exam.

What happens after I pass my exam?

CPS HR will send a copy of your exam results to you, including how many questions you got correct and how many you missed on each of the topic area subsections of the exam. Once you have received notice that you passed your exam you may apply for certification. The application you send to CDPH should include a copy of the exam results letter. CDPH will then review your experience, training, and education to determine if you meet all of the requirements for certification.

When can I apply for certification?

Apply to CDPH after CPS HR has notified you that you have passed the exam
