The purpose of this study is to design a Moroccan Trail Making Test B; explore the effects of age, education and gender on the performance of the Trail Making Test (TMT); and provide normative information in Moroccan subjects. Our normalization study was conducted on 348 subjects (156 female and 192 male). The subjects were classified into four groups based on age (18 - 39 years, 40 - 59 years, 60 - 69 years and ≥70 years), and three groups based on educational level (3 - 6 years, 7 - 10 years and ≥11 years). The data were analyzed using descriptive statistics through SPSS. The results displayed that increasing age and decreasing levels of education significantly result in a decreased performance on the Trail A, Moroccan Trail B and English Trail B. Only 229 bilingual subjects among the 348 initial subjects completed both versions of Trail B. There was no significant difference on performance between Moroccan Trail B and English Trail B for these subjects.
