Which requirement is not included for a high liability instructor seeking certification?

The requirement regarding the completion of an advanced instructor training course is not necessary for a high liability instructor seeking certification. In Florida, high liability instructors must meet specific standards, which typically involve more foundational aspects such as submitting the application form, becoming associated with an agency or school, and completing an internship under a certified instructor. While advanced training may enhance an instructor's skills, it is not a formal requirement for obtaining certification in high liability areas like firearms or other high-risk training. The emphasis for certification is placed on adherence to established procedures and demonstrating competencies through hands-on experiences and internships rather than advanced training courses.
