uncertified

Lacking official endorsement

Uncertified means lacking official certification or approval.

An uncertified teacher hasn't completed required credentialing.

Uncertified mail is sent without proof of delivery.

The term often signals that someone or something hasn't met professional standards: an uncertified electrician, uncertified organic produce.

It may indicate risk or lower trustworthiness, or simply that formal verification wasn't sought.
