Preliminary Screening Report

The Preliminary Screening Report (PSR) gives you both a snapshot of an expert's testimonial history and an accurate assessment of how prolific a testifier that expert has been in the past. Most importantly, it is a tool to help you determine if there is enough information available regarding the expert to justify the investment in a full Expert Witness Profile.

The PSR has the added value of identifying challenges to the expert’s testimony in reported cases, through our sister company, The Daubert Tracker.

Because the cost of the Screening Report will be deducted from the cost of the full report, it is always best to begin the research process with a PSR.

Drawn from the broadest array of public and proprietary databases, these inexpensive ($25.00) reports include the number of times the expert’s name was found in:

  • Affidavits and Reports
  • Dockets
  • Federal Agency Decisions
  • Jury Verdict Reports
  • Motions
  • Pleadings
  • Briefs
  • Orders
  • Opinions
  • State Agency Decisions
  • Transcripts and Depositions

In summary, the PSR will give you an idea of how prolific a testifier the expert has been, whether or not there is a likelihood of challenge activity in the expert’s past and help to define the level of additional research required.

Expert Challenge Study

Learn about cases where an expert has been challenged under Daubert or their testimony has been criticized by the judge or the opposing party. See the grounds for such challenges, their outcomes (where available) and citations to underlying documents. The Challenge Study includes direct challenges to experts as well as instances where the expert's testimony/ affidavit was submitted in support or against a motion.

Like the Profile, the Expert Challenge Study is created by a team of professional expert witness researchers, all lawyers, who have access to databases not readily available to most law firms.

  • The expert’s methods were questionable, suspicious, not valid (invalid), lacking or inadequate.
  • The expert was not credible (incredible) or believable (unbelievable).
  • The testimony was outside the scope of the expertise of the expert.
  • The testimony was not relevant (irrelevant).
  • The testimony was not reliable (unreliable).

  • The testimony or opinion was conclusory.
  • Any other assessment of the expert or his/her testimony which reflects on or affects the assessment of the overall qualifications and credibility of the expert – either in a good or a bad way, particularly critical comments of any kind by the judge who wrote the opinion (even if there was no formal attempt to exclude or limit the testimony of the expert on the part of one of the attorneys.
