Assess, make a plan, do the work, and then keep measuring while you do it. Without that last part you have no way of knowing whether to push harder, change direction or stop.

Run the assessment yourself and watch while they work. Under real effort you will see the small movements, the tics and the overflow that never appear in ordinary conversation, and none of it reaches you if a technician or an app does the testing.

There is no box you type 'always late' into and get the answer out of. When a sensible strategy is not landing, the work is finding out what is blocking it rather than producing another strategy.

When a child truly does not mind losing the privilege, taking more away will not get you anywhere. That is the moment to change approach rather than raise the stakes, usually to a structured parent programme that works on the pattern between parent and child.
