Trail Making Test A and B: Normative data stratified by age and education
Tom N. Tombaugh
Abstract
Normative data for the Trail Making Test (TMT) A and B are presented for 911 community-dwelling individuals aged 18-89 years. Performance on the TMT decreased with increasing age and lower levels of education. Based on these results, the norms were stratified for both age (11 groups) and education (2 levels). The current norms represent a more comprehensive set of norms than previously available and will increase the ability of neuropsychologists to determine more precisely the degree to which scores on the TMT reflect impaired performance for varying ages and education.
