Preliminary Screening Report
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
- Federal Agency Decisions
- Jury Verdict Reports
- 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.
