How to Access: DTVP-3 - Developmental Test of Visual Perception | Third Edition | Pearson Assessments US
Age: 4-12 yrs 11 mons
Diagnoses: no specific diagnosis - children w suspected/identified visual-perceptual and/or visual-motor difficulties
Setting: pediatric OP, schools, clinics, hospitals, developmental/educational settings
assess visual perception and visual-motor integration in children and identify difficulties that may affect functional performance.
Visual perception
Visual-motor integration
Eye-hand coordination
Figure-ground perception
Visual closure
Form constancy
Copying/visual-motor skills
Time: ~30 mins
Group/Individual: Individual
Subtests:
Eye-Hand Coordination — draws precise lines within visual boundaries
Copying — copies increasingly complex geometric figures
Figure-Ground — identifies figures hidden within a complex background
Visual Closure — identifies incomplete figures by mentally completing missing portions
Form Constancy — identifies a target shape despite changes in size, position, shading, or distracting background
Instructions: child completes each task according to the specific subtest directions.
Instructions should be administered consistently to maintain standardization.
Materials:
Examiner's Manual
Picture Book
Response Booklets
Examiner Record Forms
Copying Scoring Template
User Qualifications: Level B - trained professionals
How to Score: Each subtest produces a raw score based on the child's performance.
Raw scores are converted using the normative tables provided in the Examiner's Manual.
Scores can be reported as standardized scores/percentiles and combined into composite scores.
Five subtests contribute to three composite scores:
Motor-Reduced Visual Perception
Visual-Motor Integration
General Visual Perception
Score Indications: Lower scores may indicate difficulty with the particular visual-perceptual or visual-motor skill being assessed.
Composite scores provide an overall picture of visual perception and visual-motor integration.
Results should be interpreted alongside occupational performance, clinical observations, and other assessment findings rather than used in isolation.
Reliability: Good-Excellent
Test-retest reliability coefficients for the composite scores were approximately:
Visual-Motor Integration: r = .88
Motor-Reduced Visual Perception: r = .87
General Visual Perception: r = .90
Interrater reliability was reported as > .90 across the subtests in the normative sample
Validity:
-
Strengths:
Standardized and norm-referenced
Relatively short administration time (~30 minutes)
Designed for children ages 4–12 years
Assesses both visual perception and visual-motor integration
Separates motor-reduced visual perception from skills requiring a motor response
Strong reported reliability, particularly for composite scores
Useful for identifying specific areas of visual-perceptual difficulty
Weaknesses:
Limited to children 4:0–12:11, so it cannot be used with adolescents/adults outside the normed age range.
Requires Level B qualification
Commercial assessment with a relatively high purchase cost
Requires specialized materials/manual
Some subtests require fine motor/graphomotor responses, so motor impairment can influence performance
