Certifications are official documents that verify an individual's skills, knowledge, or qualifications in a specific area. They are often awarded by professional organizations or educational institutions after a person completes a course or passes an exam. Certifications can enhance a person's resume and demonstrate their expertise to potential employers. Many industries, such as information technology, healthcare, and project management, offer certifications to help professionals stand out in a competitive job market. Examples include the Certified Information Systems Security Professional (CISSP) and the Project Management Professional (PMP). These credentials can lead to better job opportunities and career advancement.
