This study provides new norm scores for the Box and Block Test for gross manual dexterity in children ages 3-10 yr. Two hundred fifteen Dutch children performed the Box and Block Test separately with each hand. We found an age effect for the scores; older children obtained higher scores than younger children. Concurrent validity was assessed by means of comparison with the manual dexterity subtests of the Movement Assessment Battery for Children-2; correlations were significant. Intraclass correlation coefficients for test-retest and interrater reliability measures were .85 and .99, respectively. The Box and Block Test is an easy, feasible, valid, and reliable measurement for gross manual dexterity in young children. The obtained norms can be used in clinical settings to compare the gross manual dexterity of atypically developing children with that of age-related peers and to evaluate efficacy of interventions. A larger international reference population is needed to increase generalizability.
