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

The following enterprises are eligible to be a NATE Testing Organization (TO):

  • Manufacturers
  • Wholesalers/distributors
  • Contractors
  • Educational/training facilities, colleges, technical schools, libraries
  • Utilities
  • Association partners and trade association chapters

Your application will be reviewed within three to five business days, and if approved, you will be notified by email and given your TO number.
