Why is standardization important in the SFST?

Standardization is crucial in the Standardized Field Sobriety Test (SFST) because it helps to minimize bias and ensures consistency across different assessments. When officers administer the tests in a standardized manner, it allows for a uniform approach to assessing an individual's level of impairment. This consistency is vital in legal contexts, as it provides a reliable basis for the evidence presented in court. Standardized procedures also help to ensure that all individuals are subjected to the same criteria and evaluation, reducing the likelihood of subjective interpretation by individual officers. This objectivity can strengthen the validity of the results and the overall integrity of the testing process.
