Certificate of Treatment

A document a remediation company issues when work is complete, describing what was treated and how. Insurers and state compensation programs routinely require it. Ask whether a company issues one before you hire.

What kind of thing this is

Certificate of Treatment is a credential in this field. This definition comes from a standards body or an industry institution rather than from government. That makes it authoritative about practice and silent about legal obligation — a distinction worth keeping when a company cites it.

Where you will meet it

You will meet this on a company website, usually as a badge and rarely with a name attached to it. The question that turns it into information is who holds it — a credential belongs to a person or to a company, and the two are not interchangeable.

Why the wording matters

This site defines terms in under forty words wherever it can, and attaches the practical consequence rather than leaving it implied. A definition that tells you what something is, without telling you what follows from it, is trivia at a moment when nobody has room for trivia.
