Final answer:
The eligibility requirement for a Kentucky Operator's License in terms of age is at least 16 years old, which is when you can apply for a learner's permit.
Step-by-step explanation:
To be eligible to apply for a Kentucky Operator's License, one must meet specific requirements. However, the information provided references requirements for a different application process—specifically that of applying for U.S. citizenship or permanent residency, not a driver's license. To answer the student's question about the Kentucky Operator's License eligibility, age is one of the primary criteria. In Kentucky, applicants must be at least 16 years of age to apply for a learner's permit, which is the first step towards getting a full operator's license. This process also includes holding the learner's permit for a certain period, completing a driver's education course, and passing both written and driving tests.
