The TVPS-4 is the latest update of the standard comprehensive assessment of visual analysis and processing skills. The TVPS is used by many professionals, including occupational therapists, learning specialists, optometrists, and school psychologists.
The TVPS-4 remains an easy-to-use assessment for determining visual-perceptual strengths and weaknesses. Norms are based on a nationally representative sample. Additional lower-level items were added to address the needs of younger or more impaired individuals, and norms now extend through 21 years of age, making the TVPS-4 useful for a wider range of examinees.
The TVPS-4 utilizes black-and-white line drawings, bound in a convenient easel-style booklet. The items are still presented in a multiple-choice format, requiring only minimal verbal or motor (pointing) responses. This format is ideal for use with individuals who have impairments in motor, speech, neurological, or cognitive functions.
The TVPS-4 now includes 18 items in each of seven perceptual areas.
Ceilings minimize fatigue and ensure that more difficult items do not unduly tax younger students, while allowing for reliable and accurate assessment across the age range.
The TVPS-4 is consistent with current methods of visual information processing used in occupational therapy and optometry. The TVPS-4 also measures the following Cattell-Horm-Carroll theory narrow abilities.
- Flexibility of Closure
- Visual Memory
- Memory Span

The TVPS-4 is individually administered, is untimed, and takes about 25 minutes to complete. Scoring is quick and uncomplicated. Raw scores are reported as scaled scores and percentile ranks for each subtest; the overall total score is reported as a standard score and percentile rank. Age equivalents are also provided for the subtest and overall scores.
