Our DOT Consortium Membership includes quarterly random selections, notifications by email & phone, testing site coordination, MIS reporting, and a Certificate of Compliance upon enrollment. Owner-operators DOT-regulated employers Certificate of Compliance.
Owner Operators- DOT requires all owner-operators to enroll in a consortium so they are included in a compliant random testing pool because they cannot randomly test themselves.
Small Employers-Some smaller companies may not have enough drivers or safety-sensitive employees to maintain their own statistically valid random pool. Therefore, by joining a consortium, they are combined with other companies to form a large pool that meets DOT testing requirements.
Large Employers-Larger fleets may manage their own random pool but often use a consortium/TPA to outsource the process, reduce administrative burden, and ensure strict compliance.

I reached out Accredited Drug Testing/Secure Screenings to partner for my drug testing business (Discovery Diagnostics Columbia SC) and the process was extremely easy. I worked with Sicilia who was amazing. She was friendly & knowledgeable, and answer all of my questions with ease.

Accredited has been wonderful to work with! My court ordered tests are on a very strange schedule but every time I call, they are quick to schedule me and are always able to find a location that works for where I’m at and when! Thank you for making this rather undesirable situation less stressful and efficient.
