Which OSSF licenses require previous experience?

The correct answer is B because both Installer II and Site Evaluator licenses require prior experience in the field. Installer II, which involves more complex installation tasks, necessitates a background in previous installation processes to ensure that the individual possesses the needed skills, knowledge, and judgment to make sound decisions in various situations. The Site Evaluator must also have experience to accurately assess and evaluate sites for on-site sewage facilities, as their responsibilities include evaluating soil characteristics, drainage, and other environmental factors critical for proper site assessment.

Licenses like Installer I may not require as much experience, as they tend to focus on basic installation tasks. Similarly, the Maintenance Provider, while significant, may not necessarily demand prior on-the-job experience in the same way more advanced licenses do. Hence, it’s crucial for individuals seeking these advanced licenses (Installer II and Site Evaluator) to have prior relevant experience to ensure they can operate effectively and safely in their roles.
