The Trail Making Test is a Neuropsychological test consisting of two parts, A and B,

designed to assess a subject’s visual attention and task switching ability.*

Part A tests cognitive processing speed. The subject has to consecutively connect the

numerical points accurately, in ascending order, from 1 to 25 as quickly as possible,

i.e., 1, 2, 3 etc.

Part B tests executive functioning. The subject has to consecutively connect both

numerical and alphabetical points accurately, in ascending order as quickly as

possible. i.e., 1, A, 2, B, 3, C, etc.

The purpose of the test is to ascertain an overall time for completing both parts and

gain information about:

• Visual search speed

• Scanning

• Speed of processing

• Mental flexibility

• Executive functioning
