Which of the following is NOT a requirement for CCAs?

The requirement for City Carrier Assistants (CCAs) does not include having prior postal experience. This is significant because CCAs are often entry-level positions designed for individuals who may not have previous experience in the postal service or similar roles. The Postal Service provides training for all new employees, equipping them with the necessary skills to perform their duties.

In contrast, the other options reflect legitimate requirements for becoming a CCA. Possessing a valid driver's license is necessary because delivery routes require driving postal vehicles. Being at least 18 years old is also a standard criterion for employment, ensuring that candidates are legally able to work and assume responsibilities of the job. Additionally, passing background checks is crucial to ensure the safety and security of postal operations and uphold the integrity of the postal service.
