Illinois Agility Test Calculator

About this calculator

The Illinois Agility Test measures how quickly you can change direction under control by running a fixed course — cones set out over roughly 10 x 5 meters with a slalom section through the middle — timed from start to finish, converting a single stopwatch reading into a standardized measure of change-of-direction speed. Because the course layout is fixed and widely standardized, results are directly comparable across athletes and over time.

Coaches in soccer, rugby, basketball and other change-of-direction-heavy sports use the Illinois test in pre-season fitness testing and talent assessment because agility — not just straight-line speed — predicts performance in sports built around cutting, dodging and rapid direction changes; published normative tables let a coach rank an athlete’s time against age- and sex-matched adult benchmarks rather than judging it in isolation.

This calculator takes your Illinois agility test completion time and returns your agility rating and percentile against standard adult norms.
