What Are Computer Science Certifications?
Tech professionals earn computer science and IT certifications to demonstrate skills, knowledge, and areas of competency and/or expertise.
Unlike licenses, which the government may require for jobs in healthcare or education, certifications are voluntary. These credentials also differ from academic certificates — which educational institutions confer.
Professional organizations typically provide computer science certifications. To qualify for certification, applicants usually must pass an exam. The time it takes to earn a certification varies depending on the candidate's previous knowledge and whether they complete certification courses.
The tech industry prefers or requires certifications for some positions. Candidates can pursue various computer science certifications for different specializations and levels of experience.
