Time the training person as he or she connects the "trail." If the patient makes an error, point it out immediately and allow them to correct it.Įrrors affect their score only in that the correction of errors is included in the completion time for the task. The training person should be instructed to connect the circles as quickly as possible, without lifting the pen or pencil from the paper. In Part B, the circles include both numbers (1 – 13) and letters (A – L) as in Part A, you should draw lines to connect the circles in an ascending pattern, but with the added task of alternating between the numbers and letters (i.e., 1-A-2-B-3-C, etc.). In Part A, the circles are numbered 1 – 25, and the training person should draw lines to connect the numbers in ascending order. 12, 91–96, 1941.Both parts of the Trail Making Test consist of 25 circles distributed over a sheet of paper.
