How the Test Works
Watch the Box
A grey box appears on screen—stare at it continuously
React to Changes
Click immediately when the box turns black
Stay Alert
Maintain focus for the full test duration (3-30 minutes depending on test)
Expert Tips to Pass
Stay Focused
The box changes infrequently. Don't let your mind wander—stay visually locked on the target area.
React Fast
Click immediately when you see the change. Even a fraction of a second delay affects your score.
Find Your Rhythm
This is an endurance test. Pace yourself mentally to maintain alertness throughout.
Minimize Errors
False clicks (clicking when nothing changed) hurt your score more than missed targets.
Frequently Asked Questions
WAFV stands for Watch and Find Video. It's a vigilance test where you watch a grey box on screen and click immediately when it turns black. The actual assessment runs for 30 minutes.
We offer 4 practice tests: a 3-minute sample, and full tests at 10, 20, and 30 minutes. Start with the sample to try it out, then progress to longer tests that build real endurance.
The timing varies. Sometimes it changes quickly, other times there are long gaps. This unpredictability is part of what makes the test challenging.
Missed changes reduce your score. However, false clicks (clicking when nothing changed) typically hurt your score more than missed targets.
No. The WAFV test is designed to measure sustained attention without interruption. Once started, it runs continuously. Take bathroom breaks before starting longer tests.
