A Starfleet Education Representative was a special Starfleet role in which an officer visited Federation schools to teach children about Starfleet.
One of Data's first assignments after graduating Starfleet Academy in 2345 was as a Starfleet Education Representative. In this role, he visited schools across the Sol system. Part of the information package sent to schools included film of him being asked to lift fellow cadets at the Academy as a demonstration of strength, though this was discontinued as he came to be more accepted as a person.
