The DTVP-3 provides the most recent revision of the Developmental Test of Visual Perception authored by Marianne Frostig. It is a highly reliable measure offering extended norms to age 12:11. Unlike other tests of visual perception and visual-motor integration, the DTVP-3 provides scores that are reliable at the .80 level or above for all subtests and .90 or above for the composites for all age groups.

The DTVP-3 comprises five subtests: Eye-Hand Coordination, Copying, Figure-Ground, Visual Closure, and Form Constancy.

New Features of the DTVP-3

  • New normative data were collected in 2010 and 2011
  • Norms were extended upward to age 12 years, 11 months
  • The composite scores have no floor or ceiling effects
  • Numerous eligibility and validity studies, including studies of the test’s sensitivity, specificity, and ROC/AUC, have been provided
  • The study of item bias has been expanded
  • The overall look of the test was updated

DTVP-3 Subtests

The DTVP-3 has five subtests.

  1. Eye-Hand Coordination. Children are required to draw precise straight or curved lines in accordance with visual boundaries.
  2. Copying. Children are shown a simple figure and asked to draw it on a piece of paper. The figure serves as a model for the drawing. Subsequent figures are increasingly complex.
  3. Figure-Ground. Children are shown stimulus figures and asked to find as many of the figures as they can on a page where the figures are hidden in a complex, confusing background.
  4. Visual Closure. Children are shown a stimulus figure and asked to select the exact figure from a series of figures that have been incompletely drawn. In order to complete the match, children have to mentally supply the missing parts of the figures in the series.
  5. Form Constancy. Children are shown a stimulus figure and asked to find it in a series of figures. The targeted figure will have a different size, position, and/or shade, and it may be hidden in a distracting background.

DTVP-3 Composites

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.
