Practitioner’s Guide
to Group Testing
The definitive guide for practitioners implementing group testing into practice.


Group testing has a lot going on.
Testing large groups introduces logistical, technical and communication challenges – from managing flow and fatigue to maintaining data quality and delivering meaningful outputs at scale.
Drawing on real-world examples across sport, health, workplace and education settings, this guide distills best practice for planning, executing and reporting on group testing sessions using objective measurement technology.
Some questions we'll answer in this guide:
- Q: How do I plan an effective group testing event?
- Q: Which testing options are best suited for high-volume environments?
- Q: How do I manage participant flow and logistics at scale?
- Q: How can I interpret, report and deliver group testing data effectively?
... and much, much more.
When baseline or combine testing for large groups of athletes, it’s imperative that the tests are repeatable, reliable, efficient and valid.
When you’re assessing hundreds of athletes, efficiency and consistency matter more than novelty. The right tools allow you to collect meaningful data quickly and actually apply it beyond the testing day.
When testing large groups, the manual hurdles of the past often led to a lack of objective guidance, leaving practitioners to rely on intuition rather than high-fidelity evidence. With VALD, we’ve eliminated that compromise.
We’ve tested thousands of elite high school athletes across hundreds of events dating back decades. However, since introducing VALD technology, including SmartSpeed, ForceDecks and DynaMo, we’ve been able to take our collection and evaluation processes to the next level.
By running more than 1,000 showcases annually across 45 states – and testing over 50,000 players each year – we make it easy for athletes to access Prep Baseball events close to home while still competing against a national
benchmark. To support that scale, we rely on technology that’s durable, resilient and consistent, allowing us to efficiently reach players regardless of the facility or infrastructure in their backyard.
