CDPH Lead Inspector/Assessor California State Practice Exam

What is an essential characteristic of targeted sampling?

1. It includes random selections

2. It is based on owner-provided information

3. It avoids any visual assessment

4. It focuses on historical data from previous evaluations

The correct answer is: It is based on owner-provided information

Targeted sampling is an approach used in lead inspection and assessment that relies on specific and relevant information provided by property owners or occupants. This method allows inspectors to concentrate their efforts on areas of a property that have a higher likelihood of lead presence based on the information received. For instance, if a homeowner knows their property has lead-based paint in certain rooms or areas, targeted sampling can direct the inspection resources effectively. Unlike random selections, targeted sampling is not comprehensive and does not aim to cover the entire property indiscriminately; instead, it zeroes in on specific locations of concern. It also does not avoid visual assessments entirely, as these assessments can help inform where sampling should take place. While historical data from previous evaluations can be valuable in the overall assessment process, the essential characteristic of targeted sampling is the reliance on the insights and information provided by the property owner, which directs the inspector’s focus.
