The Daubert Test establishes the judge as the "gatekeeper" of expert testimony.
In determining the validity of expert testimony, the court must evaluate a two-prong test:
- Determine whether the expert testimony reflects "scientific knowledge," whether it is "derived by the scientific method," and whether the work amounts to "good science."
- Also known as the "fit" requirement
- The proposed expert testimony must be "relevant to the task at hand" by advancing a material aspect of the proposing party's case.
