Training refers to completing a course, qualification refers to passing an exam, and certification verifies a level of compliance that is revisited periodically through testing or audits. Credentialing recognizes measurable skills based on standards, while accreditation provides formal third-party recognition of competence to perform tasks. Most companies provide training through online courses, webinars, or self-paced learning, and aim for qualifications but often lack robust certification processes involving ongoing assessments. Few achieve credentialing or accreditation due to their greater costs and requirements.
