What is required for a witness to qualify as an expert under Rule 702?

A witness qualifies as an expert under Rule 702 when their specialized knowledge significantly aids the trier of fact in understanding the evidence or determining a fact in issue. This rule emphasizes the necessity of having relevant expertise that will assist the judge or jury in making informed decisions based on the particular subject matter.

The focus is on the knowledge and experience related to the specific area that is being addressed in the case, rather than solely relying on formal qualifications or recent trial involvement. While having a formal degree or extensive field experience can certainly contribute to an expert's credibility and knowledge, it is the relevance of that knowledge in relation to the facts of the case that is paramount. Therefore, the ability to provide insight and understanding that is beyond the average layperson's grasp is what qualifies a witness as an expert under this rule.
