In ACL 3 High, observe to see if the person can use lines to organize their actions in coloring and placement activities.
To Verify
The concept of a line is strong in ACL 3 High. Provide the person with a simple picture to color in. Can they color within the line? If they can color within the line or follow the outline of the picture this verifies ACL 3 High.
In the clover or the flower pot activity, see if they form rows or columns or try to fill all spaces. This verifies ACL 3 High.
To Rule Out
To rule out ACL 4 Low, simply ask the person what are they doing? If they cannot tell you then they are not goal-directed and are not grounded by doing a manual action.
