[ Description ]
● The TVPS-4 is the latest update of the standard comprehensive assessment of visual analysis and processing skills. 
● The TVPS-4 can be 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-Horn-Carroll theory narrow abilities:

● Visualization
● Flexibility of Closure
● Visual Memory
● Memory Span

[ Administration and Scoring ]
● 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.
