Stay alert: sustained attention practice

A circle jumps across a grid, usually one step at a time. Occasionally it jumps two steps, and you respond only to those. The full test runs for 10 minutes, like many real vigilance tests. It measures sustained attention: staying accurate when little happens for long periods.

Why it matters for ATC selection

Vigilance tests are used in ATC selection because quiet periods are when mistakes happen. A controller must spot the one thing that changes after an hour of routine.

How the practice works

• A circle jumps across the grid, usually one step at a time.
• Occasionally it jumps two steps in one go. Press Space, or tap Double jump, whenever that happens.
• Don't respond to single jumps.
• The exercise runs for 10 minutes, the same length as many real vigilance tests.

The full-length test is part of full access. Every practice item is original. Full access adds feedback on where you lost marks and how to improve.

Tips

• Expect accuracy to drop after a few minutes. That is normal, and practice reduces it.
• Keep your eyes on the target, not the whole screen.
• Only respond to clear double jumps. If you are unsure, it was probably a single.
