Before testifying as an expert witness, what must an attorney do first?

• A. Qualify you as an expert witness
• B. Prove that the tools you used to conduct your examination are perfect
• C. Read your curriculum vitae to the jury
• D. Engage in damage control

Answer: (A)

Establishing admissibility rests on the witness's qualifications. Before an expert can testify, the attorney must show the court that the person has the specialized knowledge, training, education, and experience needed to assist the trier of fact in understanding the technical aspects of the case. This process, sometimes called laying a foundation, demonstrates that the witness is truly an expert in the relevant field, which is what allows their opinions to be admitted as expert testimony. The judge (and often opposing counsel) evaluates whether the witness meets the required standard for expertise, such as Daubert or Frye in many jurisdictions, before any expert opinion can be presented. Proving that the tools used are perfect is not required; in forensic practice, tools are validated and their limitations acknowledged, but no one expects perfection. The key is demonstrated reliability and appropriate use, not flawless performance. Reading a curriculum vitae to the jury isn’t the actual first step in admitting testimony—credentials are typically reviewed during the qualification process, and the CV itself isn’t something the jury relies on for entry of testimony. Damage control isn’t a procedural step in getting an expert to testify. So the essential first action is to qualify the witness as an expert, establishing their credentials and relevance to the case.
