The TVMS-3, or Test of Visual-Motor Skills, Third Edition, is a standardized design-copying test published by Academic Therapy Publications (ATP) and written by Nancy A. Martin. The test-taker looks at 39 geometric designs and copies each one by hand while the original stays in view, and a trained examiner scores how accurately the copies match. The publisher lists a norm-referenced age range of 3 years 0 months through 90 and older. The TVMS-3 is not an IQ test. It measures "visual-motor integration," the ability to coordinate what the eyes see with what the hand draws, while an intelligence test estimates general reasoning ability across verbal, quantitative, spatial, and memory tasks. This article covers what the TVMS-3 measures, how it is given and scored, what the research shows, and how it compares with related tests.
What the TVMS-3 measures
According to Academic Therapy Publications, the TVMS-3 "assesses how well a person can coordinate visually guided fine-motor movements to copy a design while it is in sight." The publisher describes its purpose as finding systematic distortions or gross inaccuracies in the copied designs that could result from deficits in visual perception, motor planning, or motor execution.
That last phrase matters. Copying a shape is a chain: the eyes take in the design, the brain interprets its parts, the person plans a sequence of hand movements, and the hand carries them out. A breakdown anywhere in the chain produces an inaccurate copy, and the TVMS-3 alone cannot say which link failed. The publisher therefore recommends pairing it with a "motor-free" visual perception test, one in which the person only points to or names an answer and never draws. Used together, the publisher reports, the two results can differentiate a primarily visual-motor impairment from a perceptual difficulty.
The test's lineage runs back to the original Test of Visual-Motor Skills by Morrison F. Gardner, published in 1986, as documented in a 2018 review by Ted Brown and Lisa Peres in the Hong Kong Journal of Occupational Therapy. Earlier revisions split the instrument into a lower-level form (TVMS-R) and an upper-level form (TVMS-UL). The third edition combined them, simplified the scoring so that no ruler or protractor is needed, and extended the age range to 90 and older with national norms. ATP lists the TVMS-3 as its current edition; no fourth edition appears on the publisher's site as of this writing.
How the test is administered
The publisher's product page describes the procedure in a few sentences. The test-taker receives a booklet containing 39 geometric designs of increasing complexity and is asked to reproduce each one as closely as possible. Sketching and tracing are not allowed, and only one attempt per design is permitted. The test is untimed. ATP states that it can be administered in about 25 minutes and lists a combined testing and scoring time of 30 to 45 minutes.
• Who can give it: ATP classifies the TVMS-3 at Qualification Level B, which by the publisher's definition requires at least a master's degree with state licensure or certification from a professional organization such as ASHA, AOTA, or APA that requires training in psychometrics and test interpretation. Occupational therapists, school psychologists, and educational diagnosticians are the usual examiners.
• Individual or group: Unlike most cognitive tests, the TVMS-3 can be given to an individual or a small group, according to the publisher, because the task is simply to copy designs into a booklet.
• Materials and norms: The complete kit consists of the manual, 15 test booklets, and 15 record forms. ATP reports that the test was nationally norm-referenced on 2,610 individuals.
How the TVMS-3 is scored
Scoring is the part of the third edition that changed most. Instead of measuring angles and line lengths with tools, the examiner compares each copy against guidelines and exemplars in the manual and records the errors observed. The record form shows which errors are possible on each design. The publisher identifies nine error types:
• Incorrect closures: shapes left open, or lines crossing where they should meet.
• Incorrect angles: corners drawn sharper or wider than the model.
• Line quality: wobbly, broken, or overdrawn lines.
• Line lengths: segments clearly longer or shorter than the original.
• Line connections: parts that should join are separated or overshoot.
• Modification of size or part: a component drawn out of proportion.
• Addition or deletion of a part: an element left out or added.
• Rotation or reversal: the design or a part of it turned or flipped.
• Shape overlap error: overlapping figures drawn with the overlap wrong or missing.
Results are expressed as a general accuracy "standard score," a score placed on a fixed scale so it can be compared with the norm group, along with the error analysis. The publisher states that results can be reported as standard scores, percentile ranks, or age equivalents. The error analysis is meant to be the clinically useful part: two people can earn the same accuracy score for different reasons, and the pattern of errors points a therapist toward different interventions. The manual includes a scoring tutorial with annotated exemplars and practice exercises, which matters because judgment-based scoring is only as consistent as the training behind it.
What the research says about reliability and validity
The TVMS-3 was reviewed in the Buros Center's Nineteenth Mental Measurements Yearbook, the standard independent reference for published tests. Peer-reviewed evidence outside the manual is still thinner than for the Beery VMI, which has a much larger literature.
The most direct recent study appeared in the American Journal of Occupational Therapy in 2024. Shu-Fu Hsu and colleagues gave the TVMS-3 twice to 57 kindergarten children in Taiwan diagnosed with developmental coordination disorder. They reported that the accuracy score showed excellent test-retest reliability and acceptable random measurement error, and that it correlated well with the Vineland Adaptive Behavior Scales, Third Edition. One study of 57 children in one country is a start rather than a settled verdict.
There is broader evidence that visual-motor integration matters for schoolwork, mostly gathered with the Beery VMI. In a 1999 study in Optometry and Vision Science, Marjean Taylor Kulp assessed 191 children in kindergarten through third grade and found that visual-motor integration scores were significantly related to teachers' ratings of reading, math, writing, and spelling, and to scores on a school ability test. Findings like these are why school teams take visual-motor scores seriously when a child struggles with handwriting or copying from the board. They show that the two skills travel together in young children, which is a different thing from being the same skill.
TVMS-3 versus the Beery VMI, TVPS-4, and MVPT-4
All four instruments are published by ATP, and the differences are mostly about whether drawing is required and what ages are covered.
• Beery VMI: The Beery-Buktenica Developmental Test of Visual-Motor Integration is the most widely researched design-copying test and the closest cousin to the TVMS-3. ATP lists it for ages 2 through 100, and it includes supplemental tests of visual perception and motor coordination, whereas the TVMS-3 offers a single accuracy score with a detailed error taxonomy.
• TVPS-4: The Test of Visual Perceptual Skills, Fourth Edition, also by Nancy Martin, is motor-free: the test-taker looks at pictures and picks answers without drawing. ATP lists it for ages 5 through 21. It is the natural companion to the TVMS-3 when an examiner wants to separate perception from motor output.
A low TVMS-3 score with an average score on a motor-free test suggests a problem in motor planning or execution; low scores on both suggest a perceptual component. Neither pattern speaks to how well the person reasons.
Why a TVMS-3 score is not an IQ score
The mainstream scientific definition of intelligence, set out in a 1997 statement in the journal Intelligence signed by 52 researchers and edited by Linda Gottfredson, describes a very general mental capability involving reasoning, planning, problem solving, abstract thinking, and learning from experience. As Dr. Russell T. Warne explains in his 2020 book In the Know, an IQ test samples reasoning across many kinds of content so that the shared factor underneath them, "general intelligence" or g, can be estimated.
The TVMS-3 samples one narrow skill: reproducing a visible design by hand. A child with a tremor, an uncorrected vision problem, or simply poor pencil control can score low on it while reasoning perfectly well, and an adult recovering from a stroke can lose copying accuracy without losing intelligence. Visual-motor tests exist because these skills can be impaired independently of cognitive ability, and treating a TVMS-3 percentile as an intelligence percentile would defeat the purpose of the test.
Intelligence tests do include spatial content, and the RIOT IQ test is an example. The Reasoning and Intelligence Online Test, developed by RIOT IQ with psychometrician Dr. Russell T. Warne for adults 18 and older, uses 15 subtests across six cognitive indices (verbal reasoning, fluid reasoning, spatial ability, working memory, processing speed, and reaction time), takes about 52 minutes, and reports scores on the familiar mean-100, standard-deviation-15 scale. Its spatial ability index asks the test-taker to reason about shapes on a screen, which is a different demand from drawing them, and it does not measure visual-motor skills. It also does not replace an individually administered diagnostic evaluation. Adults who want a norm-referenced estimate of their reasoning ability can take the RIOT IQ test; anyone concerned about a child's handwriting, copying, or coordination should ask an occupational therapist or school psychologist about a visual-motor evaluation such as the TVMS-3.
