Who Assesses Visual Processing (and Who Doesn't)
As of 2026, the World Health Organization's code list has no condition titled visual processing disorder. An eye doctor checks eyesight and how the eyes work together. A school psychologist can assess learning more broadly. An occupational therapist may assess visual-motor skills. In our view, an eye exam is worth doing early. Ask for one that includes near vision.

- None of the sources we read says any one professional diagnoses visual processing disorder. Our rule is to describe patterns on these pages. We do not put a name on a child.
- The American Association for Pediatric Ophthalmology and Strabismus (AAPOS) is a US body of children's eye doctors. As of 2026, AAPOS has a page on children with learning disabilities. It says no scientific evidence suggests visual perceptual training improves their schoolwork. It says the same of vision training. In our view, an eye exam with near vision is worth doing.
Is visual processing disorder a diagnosis?
ICD-11 is the World Health Organization's list of medical codes. As of 2026, ICD-11 has no condition titled visual processing disorder. We searched its titles only.
The DSM is a US psychiatric manual. The contents list of its 2013 edition has no visual processing disorder. We could not check the newest edition's list.
None of the sources we read says any one professional diagnoses visual processing disorder. No professional body we read gives a definition of it.
On our pages, visual processing means making sense of what the eyes take in.
Nothing on this page rules anything in or out, and we are not able to.

Who checks the eyes
An eye doctor checks eyesight and how the eyes work together.
The American Association for Pediatric Ophthalmology and Strabismus (AAPOS) is a US body of children's eye doctors. As of 2026, AAPOS says a child who fails a vision screening should see an eye doctor.
In our view, an eye exam is worth doing early. Some children avoid close work, rub their eyes or lose their place. In our view, that is a reason for a full eye exam. Ask for one that includes near vision.
If an exam finds an eye problem, that problem needs its own care.
Who checks learning
A school psychologist can assess learning broadly.
The American Academy of Ophthalmology (AAO) is a US body of eye doctors. In 2017, the AAO wrote about who assesses reading trouble. It named psychologists and developmental pediatricians.
The publisher of one visual perception test lists school psychologists among its users.
Who checks visual-motor skills
An occupational therapist may assess visual-motor skills, such as copying and handwriting. One common test is the Beery VMI. Its publisher says it looks at how well a person combines seeing and moving. Ashari and colleagues (2025) reviewed the tests occupational therapists use in schools. The Beery VMI was among those used most often. We could read only the review's summary.
None of the sources on this page says a test score diagnoses a condition.
What the sources we read do not say
Each of these professionals measures something different. None of the sources we read says any one professional diagnoses visual processing disorder.
Ask each one what their test measures, and what it does not.
Our rule is to describe patterns on these pages. We do not put a name on a child.
Eye training and schoolwork
As of 2026, AAPOS has a page on children with learning disabilities. That page was last updated in 2020. It says no scientific evidence suggests visual perceptual training improves their schoolwork. It says the same of vision training.
We are not against eye care. The point is narrow.
To us, better eye skills and better reading are different claims. Ask which one a program has shown.
If your child has lost a skill
Some children could do something and now cannot. That is different from a child who has not built the skill yet. Our position is that a lost skill goes to a doctor first, not a tutor.
When to ask for help
Each of these is a reason to ask for help on its own.
- Little change, even with steady practice and good teaching.
- Schoolwork well below what school expects.
- A teacher who raises a concern about learning.
- Extreme upset about schoolwork.
- Complete avoidance of school or learning.
- Hopelessness about learning.
- Sadness or worry that lasts.
- Significant delays in speech, language or motor development.
- A skill that was there and has gone. Our position is that a lost skill goes to a doctor first, not a tutor.
If no skill has gone, start with the teacher. Say what you are seeing at home, and what you have tried. Beyond the teacher, the right person depends on what it turns out to be about. If the work is too hard, someone who works on that school skill. If worry or mood is the thing, someone who works with children's mental health. In our view, delays in speech, language or movement are worth raising with your child's doctor. In our view, if you are worried enough to ask, a professional evaluation is worth asking about.
Any talk of hurting themselves is a same-day call to your doctor or a crisis line.
In the classroom
If a student's work on the page worries you, describe what you see, not the eyes.
Two sentences for an email home: "She finds copying from the page slow. Has anyone checked her eyes recently?"
Tonight, write down what you have been told about your child's visual processing, and by whom. Next to each, write one question: what does your test measure, and what does it not? This is a record, not a test.

An overview of processing skills. Our work on each runs alongside reading, spelling or math instruction, not in place of it.
