1. Someone else makes a nomination
Universities define who can nominate. The eligible group may include faculty, alumni, trustees, staff, members of the university community or the public. A nomination normally explains the person's achievement, service and connection to the university's criteria.
The University of Pennsylvania, for example, welcomes nominations from its community across fields including arts, business, education, public affairs, scholarship and science. It expressly excludes self-nominations and instructs nominators not to contact the nominee.
Hardin-Simmons University's published guidelines permit nominations from specified alumni, faculty, staff, emeriti and recognised board members. They also exclude self-nominations and proposals where the intended recipient appears to have encouraged or actively participated.
These examples show why “submit your own application” is a warning sign. A person can be nominated only through the conferring institution's genuine process and eligibility rules.
