About This Product

The third edition of Marianne Frostig’s popular Developmental Test of Visual Perception offers a useful measure of visual perception and visual–motor integration skills in children. It is composed of five subtests:
- Eye–Hand Coordination
- Visual Closure
- Form Constancy
Subtest results provide three composite scores: Motor–Reduced Visual Perception, Visual–Motor Integration, and General Visual Perception.
Scores for the five subtests are reliable at .80 or higher, and scores for the three composites are reliable at .90 or higher. These scores are validated by numerous studies and normative data based on a large representative sample (N = 1,035). The DTVP-3 is shown to be unbiased in regard to race, gender, and handedness.
The DTVP-3 is especially useful in identifying candidates for special programs, providing evidence of possible organic impairment, and verifying treatment effectiveness.
