Standardized vs non-standardized testsFieldSobrietyTests.org take a look at how field sobriety testing works in action. First, there are two types of these tests. One is standardized and one is non-standardized. There are more non-standardized tests, but fewer officers use them. Why? Because these tests do not have a set rubric. Standardized tests do. This makes them more objective. For non-standardized tests, results rely on the individual officer’s judgment. This leaves room for bias.
What do standardized tests check?There are only three types of standardized tests. This includes the one-legged stand, the walk-and-turn and the horizontal gaze nystagmus. Each test checks an area that alcohol may affect. This includes:
- Spatial awareness
- Ability to follow instructions
- Temperament and belligerence
