Which of the following OSSF licenses requires previous experience?

The requirement for previous experience is essential for both the Installer II and Maintenance Provider licenses due to the complexity and hands-on nature of the tasks involved in on-site sewage facilities.

For the Installer II license, candidates must demonstrate a higher level of knowledge and competency in installing OSSFs. This includes understanding local regulations, soil evaluation, system design, and installation techniques, all of which benefit greatly from prior hands-on experience.

Similarly, the Maintenance Provider license demands familiarity with the operation and maintenance of on-site sewage systems. Individuals in this role need to effectively troubleshoot and address issues that may arise in sewage systems, which is best achieved through practical experience in the field.

In contrast, the Installer I license is designed as a starting point, focusing more on entry-level skills and knowledge, thus it does not mandate previous experience. Therefore, the response that highlights the requirement of experience for both Installer II and Maintenance Provider is accurate, reinforcing the need for a solid foundation before advancing to these more specialized roles.
