Credentials are documents or qualifications that prove a person's abilities, skills, or knowledge in a specific area. They can include degrees, certificates, licenses, or any other official recognition that demonstrates expertise. For example, a doctor needs a medical degree and a license to practice, while a teacher may require a teaching certificate. Having the right credentials is important because they help employers and clients trust that a person is qualified for a job. In many fields, such as engineering or law, credentials are essential for gaining employment and advancing in a career. They serve as a way to verify that someone has the necessary training and experience.
