Which of the following is NOT a requirement to become an expert witness?

To become an expert witness, individuals typically do not need to hold a specific type of degree. While having relevant education can enhance one's credibility, the legal system recognizes expertise in various forms, including practical experience and professional reputation. As such, an individual could qualify as an expert witness based on their extensive practical experience, familiarity with the case at hand, and recognition within their field of expertise, even if they do not possess a formal degree in the area. This flexibility allows for a broader range of witnesses to provide valuable insights based on their knowledge and direct experiences related to the case involved.
