Drug Recognition Expert

The Drug Evaluation and Classification Program (DECP) trains police officers and other approved public safety officials as Drug Recognition Experts (DREs) through a three-phase training process:

  • Drug Recognition Expert Pre-School (16 hours)
  • Drug Recognition Expert DRE School (56 hours)
  • Drug Recognition Expert Field Certification (Approximately 40 – 60 hours)

The training relies heavily on the Standardized Field Sobriety Tests (SFST’s), which provide the foundation for the DEC Program. Once trained and certified, DREs become highly effective officers skilled in the detection and identification of persons impaired by alcohol and/or drugs. DREs are trained to conduct a systematic and standardized 12-step evaluation consisting of physical, mental and medical components. Because of the complexity and technical aspects of the DRE training, not all police officers may be suited for the training. Experience has shown that training a well-defined group of officers proficient in impaired driving enforcement works well and can be very effective.
