The Drug Recognition Evaluation is a systematic process because it is based on a complete set of observable signs and symptoms known to be reliable indicators of drug impairment. A drug recognition expert never reaches a conclusion based on any one element of the examination, but instead on the totality of facts that emerge.

Standardization is very important, because it helps to:
The Drug Recognition Expert Procedure can be broken down into twelve major components. The National Highway Traffic Safety Administration Drug Evaluation and Classification Program Drug Influence Report Checklist contains the twelve components in the sequence in which they must be performed. The Drug Recognition Expert must always follow the checklist when conducting an examination.
If the law enforcement officer has not administered and evaluated the Drug Recognition process in the REQUIRED SYSTEMATIC AND STANDARDIZED MANNER, she/he will not obtain the validated indicators of impairment based on scientific research.
