The DTVP-3 is unique in that its scores are reliable at the .80 level or above for all subtests and .90 or above fore the composites for all age groups. The assessment scores are validated by many studies and features norms based on a large (N = 1,035) representative sample. The DTVP-3 yields scores for both visual perception (No motor response) and visual-motor integration ability and it is shown to be unbiased relative to race, gender, and handedness

The DTVP-3 has five subtests: Eye-Hand Coordination, Copying Figure-Ground, Visual Closure, and Form Constancy. The results of the five DTVP-3 subtests are combined to form three composites: Motor-reduced Visual Perception, Visual-Motor Integration, and General Visual Perception (combination of motor-reduced and motor-enhanced subtests). Subtests were assigned to a particular composite on the basis of the amount of motor ability required by their formats.
Norms based on a large (N = 1,035), representative sample. Normative data were collected in 2010 and 2011.
