Homonym: Credential (Qualification)
A credential is a document or proof that verifies a person's qualifications, skills, or identity. Common examples include diplomas, certificates, licenses, and identification cards. Credentials are often required for jobs, educational programs, or professional licenses to ensure that individuals meet specific standards.
In many fields, such as healthcare or education, having the right credentials is essential for gaining trust and credibility. For instance, a doctor must have a medical license as a credential to practice medicine, while a teacher needs a teaching certificate to work in schools.
