In Testifying as an expert witness in computer crimes cases, Deb Shinder writes:
To testify as an expert, you must be formally qualified and accepted as such by the judge presiding over the case. This qualification process is generally “on the record,” with questions asked of the witness in court to establish his/her expert status (this is called a voir dire examination). Because juries tend to believe whatever a professed expert says without question, judges must be convinced that you are competent, knowledgeable, and credible before allowing you to testify. To establish you as an expert, the attorney that is calling you to testify will ask you questions about your education and training, skills and experience, awards and recognitions, and so forth. Some factors that help to establish your expertise include:
* Advanced academic degrees or advanced training in your field.
* Area(s) of specialization within the field.
* Recognition as a teacher, lecturer or trainer in your field.
* Professional licenses, if applicable.
* Membership in professional organizations; positions of leadership within such organizations.
* Publication of articles, books, and other materials, especially peer-reviewed works.
* Long-term work experience in your field.
* Technical certifications.
* Awards and recognitions within the industry.
