Review Process

Upon receipt of the TOS Logo Usage Guidelines Authorization Form, TOS communication’s department and TOS’s Executive Director will review the request. If there is any question as to whether allowing the request would pose concern to TOS’s brand, the request will be passed to TOS’s Ethics Committee for review. The Ethics Committee will be provided two business days to review and discuss the request, and at least two-thirds of the committee must agree before the request is either confirmed or denied. If the Ethics Committee cannot come to an agreement, the request will then be sent to the Council for a final decision.
