Uncertified

Uncertified is an adjective describing something or someone that has not received official certification from an authorized body. Certification is a formal attestation that a person, product, process, or system meets defined standards or requirements. Because certification typically follows assessment, testing, or training, an uncertified status implies the absence of that formal endorsement and, in many contexts, reduced assurance of quality or safety.

In professional contexts, many fields require certification or licensing to practice. An uncertified electrician, nurse, or teacher may be unable to work legally in jurisdictions that mandate credentials. In healthcare and public safety, lacking certification can limit duties, affect liability, and influence insurance coverage.

For products and services, certification or conformity assessment ensures compliance with safety, performance, or environmental standards. Uncertified devices or goods may not bear recognized marks and may pose risks or be restricted from sale.

In software and digital domains, certification can refer to vendor or third-party validations, code signing, or security and quality attestations. Uncertified software or unsigned drivers may be flagged as untrusted or incompatible, affecting installation and support.

Certification schemes vary by region and field, with some requirements mandatory by law and others voluntary for professional credibility. Certifications may expire or require periodic renewal, continuing education, or re-testing. Distinctions should be drawn from related terms: uncertified is not the same as unverified (not yet confirmed), unaccredited (not recognized by an accrediting body), or unlicensed (no legal license).
