Eleven Steps Toward Admissibility

To increase the probability that the expert's tests, experiments, demonstrations and models will be admissible for the courtroom, the expert should follow these steps:

  • Be thoroughly familiar with the facts of the case.
  • Have accurate measurements available.
  • Be familiar with the progression of events that occurred.
  • Use the same materials that were involved in the events.
  • Meticulously track tests or experimental steps.
  • Record the tests or experimental events carefully.
  • Make demonstrations similar to the actual events that occurred.
  • Make models to precise scale.
  • Detail all findings, both positive and negative.
  • Do sufficient research to establish that the test or experimental procedure is scientifically and technically recognized as authoritative.
  • Consult with counsel to ensure the best presentation for admissibility.
