SCAAT

Sustained concentration with attention switching

Six pages of dot boxes. The target changes on every page - you are told the new rule before each one. Ninety seconds per page.

Free run: the first 20 questions

You will sit the first 20 questions of this test and get your score for them. Unlock it for $7.99, or every test for $25, to sit the full paper and see the breakdown behind the score. What unlocking adds

Before you start

One page of 20 boxes, 18 seconds. The page does not pause.
Click a box to mark it. Click it again to unmark. Only the final state counts.
Leaving this tab voids the attempt. A concentration test that was paused measures nothing, so it is discarded rather than resumed.
