The Test of Gross Motor Development (TGMD) is a process-oriented scale that provides qualitative information on children’s motor competence. The aim of the current study was to analyze the psychometric properties by examining the internal consistency and construct validity of the Spanish version of the TGMD-3. A sample of 178 typically developing children (47.5% girls) between the ages 3 and 11 years participated in this study. Reliability and the within-network psychometric properties of TGMD-3 were examined by using internal consistency and confirmatory factor analysis. Reliability indexes were excellent (> 0.89). A two-factor structure model was hypothesized and an alternative unifactorial model was also tested. Adequate fit indexes in both a two-factor model [ball skills seven items and locomotor skills six items (χ2 (64) = 139.200, p < .010, RMSEA = 0.073, SRMR = 0.050, NNFI = 0.964, CFI = 0.970)] and a one-factor model [(χ2 (65) = 157.666, p < .010, RMSEA = 0.084, SRMR = 0.055, NNFI = 0.956, CFI = 0.963)] were found. The Spanish version of the TGMD-3 is thus suitable for studying children’s actual motor competence level in terms of locomotor and ball skills and also in terms of fundamental movement skills.
