An expert witness in the United States must meet a number of legal requirements. Under the Federal rules of evidence, an expert is a person with “scientific, technical, or other specialized knowledge” who can “assist the trier of fact,” which is typically a jury. A witness who is being offered as an expert must first establish his or her competency. If qualified by the court then the expert may testify “in the form of an opinion or otherwise” so long as: “(1) the testimony is based upon sufficient facts or data, (2) the testimony is the product of reliable principles and methods, and (3) the witness has applied the principles and methods reliably to the facts of the case.”
