Approved U.S. Department of Transportation Substance Abuse Professional

What is an SAP?

The Substance Abuse Professional (SAP) is a person who evaluates employees who have violated a DOT drug and alcohol program regulation and makes recommendations concerning education, treatment, follow-up testing, and aftercare.

As a SAP you represent the major decision point (and in some cases the only decision point) an employer may have in choosing whether or not to place an employee behind the steering wheel of a school bus, in the cockpit of a plane, at the helm of an oil tanker, at the throttle of a train, in the engineer compartment of a subway car, or at the emergency control valves of a natural gas pipeline. Your responsibility to the public is enormous!

As a SAP you are advocate for neither the employer nor the employee. Your function is to protect the public interest in safety by professionally evaluating the employee and recommending appropriate education and/or treatment, follow-up tests, and aftercare


How The SAP Process Works:

  •  Referral from Direct Employee Representative (DER).    
  • Set appointment with SAP for a one-on-one assessment / evaluation.
  • Administer testing tools: Addiction Severity Index (ASI) and Substance Abuse Subtle Screening Inventory (SASSI) and gather social history.
  • Recommend appropriate level of care.
  • Perform related case management and care coordination.
  • Follow-up Evaluation for compliance and return to safety sensitive duties.
  • Follow-up Testing plan.
  • Aftercare recommendations
