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
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
The TVPS-4 now includes 18 items in each of the following seven perceptual areas:
the individual is asked to find the one image, in a field of five
similar images, that exactly matches the presented target image.
the individual is presented with a target image for five seconds, is
asked to remember it and then find the image, in a field of four images,
on the following page.
Spatial Relationships: the individual is asked to find the one image, in a field of five images, that is different from the rest.
Form Constancy: the
individual is asked to find the one image, in a field of four or five
images, that matches the presented target image. The matching image may
be larger, smaller, rotated, and/or embedded within a larger design.
Sequential Memory: the
individual is presented with an image of a sequence of elements for
five seconds, is asked to remember it and then find the image with the
same sequence, in a field of four images, on the following page.
Visual Figure-Ground: the individual is asked to find a target image that is embedded in one of a field of four complex designs.
Visual Closure: the individual is asked to match an incomplete target image to the correctly completed image in a field of four.

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.
Administration and Scoring
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.
Difference from TVPS-3:
TVPS-4 utilizes the 112 black and white designs from the TVPS-3, plus
an additional 14 new images. The new images were added to expand the
range of easier items and improve the discriminative ability of the test
for younger or more impaired individuals.
