What is a key component to ensure the integrity of the SFST?

Using standardized cues and instructions is a key component to ensure the integrity of the Standardized Field Sobriety Test (SFST). This standardization is critical because it ensures that the test is administered consistently across different officers and situations. When officers use the same cues and instructions, it helps to eliminate variability that could affect the outcomes of the tests. This improves the reliability and validity of the results, allowing for accurate evaluations of a subject's sobriety.

Standardization allows for proper scoring and comparison of results, as all subjects are evaluated based on the same criteria, reducing potential bias or subjectivity in the process. Additionally, it adheres to established protocols, which can be crucial in legal proceedings where the results of the SFST may be challenged. This reduces the likelihood of errors and increases the test's overall credibility.
