Expert Qualifications and Testimony

Here's an older link, but still a very good source of information on Expert Witness qualifications and testifying as an expert.

"Expert need not be an 'outstanding practitioner in the field in which he professes expertise.' United States v. Barker, 553 F.2d 1013, 1024 (6th Cir. 1977) . 'An expert need not have certificates of training, nor memberships in professional organizations . . . . Comparisons between his professional stature and the stature of witnesses for an opposing party may be made by the jury, if it becomes necessary to decide which of two conflicting opinions to believe. But the only question for the trial judge who must decide whether or not to allow the jury to consider a proffered expert’s opinions is, ‘whether his knowledge of the subject matter is such that his opinion will most likely assist the trier of fact in arriving at the truth' Id"
