Grasp and release is the evaluation criteria for ACL 3.0 for both stitching and coloring. Both of the screening activities are brief, on purpose. The value of a screening test is that it provides a quick way to get started. Within ACL 3.0, they often grasp and release the paper and a crayon, but coloring is usually limited to vague swipes at the paper. They may not pay any attention to the effect the crayon has on the paper.
To Verify
To verify your assessment, you need to know if they can sustain their attention to grasp, release and throwing for a longer period of time with different objects and motions. The activities described below under the heading of sensory cues can all be used to verify ACL 3.0.
To Rule Out
If the person cannot sustain the back and forth motion that characterizes ACL 3.2, this confirms that they are not functioning higher than ACL 3.0.
