What Are IT Certifications?

IT certifications are industry-recognized credentials that validate specific technical skills and knowledge. Unlike degree programs that provide broad education, certifications focus on demonstrating practical competency in particular technologies, platforms, or methodologies.

Certifications are issued by technology vendors (AWS, Microsoft, Cisco), industry organizations (CompTIA, ISC2), or professional bodies. They typically require passing one or more exams and may include hands-on labs or performance-based testing. Many certifications require renewal through continuing education or re-examination.

For working professionals, certifications offer a faster path to skill validation compared to returning to school. They're particularly valuable in rapidly-evolving fields like cloud computing, cybersecurity, and DevOps where hands-on expertise matters more than theoretical knowledge.
