A certificate is an official document that verifies a person's completion of a course, training, or achievement in a specific field. It often serves as proof of skills or knowledge, making it valuable for job applications or further education. Certificates can be awarded in various areas, including academic subjects, professional development, and vocational training. Certificates can be issued by educational institutions, professional organizations, or online platforms. They may vary in format and content, but they typically include the recipient's name, the issuing authority, and details about the course or achievement. Some certificates may also carry a unique identification number for verification purposes.
