This test is normed for college grade levels or for examinees over 18 years of age who have completed high school but without college education. The importance of education has been widely disseminated throughout the United States. Adult schools and literacy programs are found in most communities. Because of the high prevalence of dyslexia, even in the adult population, it is necessary to determine the presence and severity of specific eidetic and phonetic coding problems in dyslexic adults. The ADT is the first test, and only one of its kind, to fill this need and allow for recommendations for specialized educational therapy in literacy, occupational therapy, and counseling programs, based on ADT results. The ADT comes with complete instructions, stimulus decoding pages, and recording sheets for decoding and encoding results, allowing for determination of dyslexic types and degrees of severity.
This screener is normed for grades 2 through 8. With prevalence of dyslexia ranging from 10% to 20% in elementary and middle schools, it is imperative to detect it and make appropriate referrals for further testing and diagnostic evaluation of dyslexia. TDS screening has high sensitivity and specificity for detecting dyseidetic (visual) and dysphonetic (auditory) types of dyslexia. It is an important tool for professionals on the multidisciplinary team involved in helping individuals with reading problems. These may include teachers, resource educational specialists, school psychologists, speech-language specialists, pediatricians, optometrists, ophthalmologists, occupational therapists, school nurses, and other professionals. They particularly need a dyslexia screening procedure when parents present their children with the complaint that: “My child is having trouble reading.”
A practical, easy-to-learn, direct screening method for dyslexia. This screener is normed for children in the first grade although it can be used in cases of low achieving students in the second grade or high achievers in kindergarten. Because deficits in decoding and encoding the written language are hallmarks of dyslexia, the use of phonetically regular and irregular words in the systematic manner of the DSF allows for detecting dyseidetic (visual), dysphonetic (auditory), and dysphoneidesia (auditory and visual) types of dyslexia. The DSF comes with instructions, decoding stimulus pages, and recoding forms for decoding and encoding of words.
- Visual Discrimination - the ability to discriminate dominant features of different objects, including the ability to discriminate position, shapes, and forms.
- Spatial Relationships - the ability to perceive the positions of objects in relation to oneself and to other objects. Items assess the perception of pictures, figures, or patterns that are disoriented in relation to each other, such as figure reversals and rotations.
- Visual Memory – the ability to recognize a previously presented stimulus item after a brief interval.
- Figure-Ground – the ability to distinguish an object from background or surrounding objects.
- Visual Closure – the ability to perceive a whole figure when only fragments are presented.
V.O. Stars are invaluable for demonstrating patients' visual posture and changes made due to 1) lens prescriptions or 2) as a result of vision therapy. Pads of 50.

Visual Recall is a memory skill and one of the processes of visualization. As a memory for designs test, the Visual Recall Test is a significant probe of visual behavior and was designed so that patients of all ages, with wide ranges of visual abilities, could be evaluated.
Consists of 9 Visual Recall test cards increasing in complexity from one simple design on card 1 to three more complex designs on card 9. Administration instructions and scoring information card included.
■ Visual-Motor Skills
■ Individual or Group Administration
■ Ages 3-0 through 90+
■ Nationally Norm-Referenced on 2610 Individuals
This brand-new revision of the TVMS assesses how well a person can coordinate visually guided fine-motor movements to copy a design while it is in sight. The TVMS-3 is used to determine whether there are any systematic distortions or gross inaccuracies in the copied design that could be the result of deficits in visual perception, motor planning, and/or execution.
The TVMS-3 utilizes a greatly simplified scoring system (NO ruler or protractor needed!). A single test now replaces the two levels of the previous version (TVMS-R and TVMS-UL), making it both easier to administer and more economical. This version also eliminates the need for the alternate quick-scoring method that was previously offered for the TVMS-R.
Administration and Scoring
The TVMS-3 is untimed; it can be administered completely in about 30-45 minutes. The test-taker is given a booklet containing a series of 39 geometric designs of increasing complexity. The individual is asked to reproduce each design as closely as possible but may not sketch or trace the designs, nor attempt more than one copy for each design.
Results are expressed as a general accuracy standard score and an analysis of errors seen in the copied design. The manual contains detailed descriptions and exemplars of actual test results obtained during the norming study, showing the error types and scoring guidelines. The scoring sheet has a built-in guide to the types of errors possible on each design.
Identifies nine types of errors: Incorrect Closures; Incorrect Angles; Line Quality; Line Lengths; Line Connections; Modification of Size or Part; Addition or Deletion of a Part; Rotation or Reversal; Shape Overlap Error
Analysis of the types of errors made provides a detailed evaluation of visual-motor skills. Results can be reported as standard scores, percentile ranks, or age equivalents. When used along with a test of visual perception, the tests can differentiate between a primarily visual-motor impairment and a perceptual difficulty.
Complete Test Kit includes: Manual, 15 Test Booklets, and 15 Record Forms

A breakthrough in vision science technology, the Psychometric Acuity Cards provide a high test/re-test reliability to provide excellent progress checks for amblyopia therapy. Based on the Flom cards, as modified by Davidson, these cards use tumbling "E's" arranged in a square. Complete system includes 9 double-sided, laminated cards (total of 18 charts) that represent 18 levels of Snellen acuity. Cards provide spacing between optotypes in the same ratio for all acuity levels. Complete instruction manual included.br>
This test is normed for children in kindergarten. In the beginning of schooling for a child to succeed in reading, it is critical to be able to know and differentiate the basic sounds of the language and associate them with visual symbols. He or she must be able to recognize letters of the alphabet to name them and pronounce the sound that each letter would make in a word as well as being able to write each letter correctly from visual memory. The PLCT evaluates these visual-auditory-motor abilities. The test comes with instructions, test plates, and recording forms.
