I have worked as an expert witness in the filed of waste management, infection control, hygiene and biosafety for many years, and continue to do so.
There are no specific qualifications that make you an expert witness, or even an expert! But you do need to know your subject inside out, be fully up-to-date and have a considerable experience in your field. You need to be at the top of your geame. Many so called expert witnesses are savaged at their first attempt by being unfamiliar with their subject and unable to withstand being cross-examined by an experienced QC. It's one hell of an experienced for the uninitiated - and still is after all these years! But you're not likely ever to get that far unless you can prove by your CV that you are the person for the job, and impress the instructing solicitor. They do use several registers of established experts, and look for publications, and lecturing/teaching on the subject, and compare the experience of several potential experts for each case. Once you have been accepted into the system and have a proven track record, with periodic review by legal teams you have worked with, more work generally follows.
Training is available - but its very expensive. It will not tell you anything about your specialty, but how to prepare reports, how to work in Court and elsewhere, how to present information, etc. It is well worth it but don't consider that training just to find work as an expert witness.
Don't go down this route unless you are very very very experienced in your field. You will have a duty to your clients and, more importantly, a duty to the Court, to be on top of your subject. If not, the penalties can be severe indeed. And your professional reputation is at stake. Bad news spreads fast!
As a competent person, there is some measure of experience, by time served on the job, training or qualification etc. Not so with an expert witness, but in the Courts a Judge or Barrister will soon flush out the unwary or inexperienced and dispatch them ruthless efficiency. That, plus the close vetting by the instructing solicitor before instruction is given has been considered sufficient to maintain standards.
