The score for the presence and sequencing of the numbers criteria, as part of the clock drawing test (CDT), scored out of 10.

Based on Sunderland et al.ýs 10-point rating scale from worst (score = 1) to best (score = 10) representation of a clock (Sunderland et al., 1989). However, this scale proved difficult to apply according to the criteria provided since it assumes that the representation of the hands is first and solely affected (score 6 to lo), and additional errors in the representation of numbers and the clockface occur later (score 1 to 5). Therefore, the scoring was revised to independently assess the accuracy of the representation of the clockface (maximum, 2 points), the layout of numbers (maximum, 4 points), and the position of the hands (maximum, 4 points).
