Today on the NC DWI Guy Podcast we investigate what it means for a test to be standardized. There are three Standardized Field Sobriety Tests: horizontal gaze nystagmus, walk and turn, and one leg stand. We explore the process by which these three test were standardized and what aspects of SFSTs are standardized. We also explore the value, if any, of non-standardized field sobriety tests?

Highlights:

• Learn how to utilize the NHTSA student manual in explaining what it means for a test to be standardized
• Understand the basic research that went into developing standardized field sobriety tests
• Explore the implications of the importance of standardized criteria when it comes to evaluating non-standardized testing
• Discover the problems generated in trustworthiness of testing when an officer deviates from the standardized procedures and methods during standardized field sobriety testing
