Final answer:
An inactive licensee must complete 30 clock hours of continuing education typically before applying to reactivate their license, with specific timelines varying by state and profession.
Step-by-step explanation:
When an inactive licensee wants to reactive their license, the requirement to complete 30 clock hours of education typically pertains to continuing education. These hours are a part of the reactivation process where one has to fulfill certain educational requirements set by the licensing authority, like a real estate commission or a state board, depending on the profession. In most cases, these continuing education hours must be completed before applying for reactivation of the license. However, the specific timeline for when these hours need to be completed can vary by state and the licensing body's regulations.
