Since November 1999, OTCO has been evaluated and certified annually by the USDA Agricultural Marketing Service for compliance with the International Organization for Standardization (ISO) Guide 65: General requirements for bodies operating product certification systems. This certification process involves a rigorous examination of OTCO's quality systems, including certification procedures, inspection of office files and procedures, and interviews with certified farmers and processors. ISO-65 certification allows easier entry of OTCO certified products into international markets and establishes a strong basis for reciprocity with other certification agents.

OTCO investigates all written reports of violation of its standards.The OTCO program enjoys a positive reputation because it has created and mantained high standards that safeguard both the food production and food delivery systems. However, no rules or laws can strengthen the program more than the commitmment of the operators of the OTCO certified businesses to follow the production standards with care and honesty.
