Episode notes
Prepare For Polygraph And Urine Tests
- Expect both urine testing and a polygraph when pursuing a WNBF pro card; passing both is mandatory.
- Prepare honestly and early, because the polygraph examines long-term use beyond short urine detection windows.
Polygraph Depth Beats Quick Checks
- WNBF prioritizes highly trained polygraph examiners (retired investigators) and detailed protocols to reduce false results.
- They offer investigation and clarification during testing rather than one-shot pass/fail approaches used elsewhere.
Testing Needs Multiple Layers
- Off-season and random testing strengthen credibility but remain costly; polygraph adds long-window verification that urine alone cannot provide.
- WNBF plans to extend polygraph testing into off-season checks to improve enforcement.
