The DTVP-3 is a non-verbal test designed to measure visual perception development and visual-motor integration. It is the most recent version of Marianne Frostig’s Developmental Test of Visual Perception and a second modification of the original version. The tool design was largely modified in relation to the version in use so far in Poland and this allows for a better assessment of the child’s visual perception.

The DTVP-3 includes 5 subtests (Eye-hand Coordination, Copying, Visual Closure, Form-Ground and Form Constancy) which measure visual perception skills and visual-motor skills.

The DTVP-3 allows to calculate and interpret three composite indices:

  • Visual-Motor Integration
  • Visual Perception
  • General Visual Perception

Reliability: High internal consistency of each subtest, high level of agreement among judges, satisfactory measurement stability.

Validity: Confirmed by the confirmatory factor analysis. The DTVP-3 proved to be sensitive to developmental changes of the measured skills. There are high-level correlations with other visual perception measures. The test differentiates between children without disorders and children with dyslexia and ADHD. The test also effectively differentiates between students with learning problems and those with high scholastic achievement esp. in early elementary school grades.    

Norms: For children aged 4–12 (developed on a representative sample of the Polish population).

Applicability: To assess the level of visual perception and school maturity associated with it.; to assess motor disorders in children; for screen testing of potential dyslectics.   

Please note: All of our tests are published in Polish. There are not available other language versions of our tools.
