What It Takes to Be a Testing Organization (TO)

A NATE Testing Organization is an organization that agrees to follow the NATE testing protocols and offers at least one testing session a year. A NATE TO must have a minimum of one NATE-approved proctor. A proctor can be any person who is a member of the Testing Organization, but he or she must be approved by NATE.
