You have two main paths to get your child tested for dyslexia: request a free evaluation through your child’s school or seek a private evaluation from a neuropsychologist or psychologist. Most families start with the school route, but understanding both options helps you move faster and get the right support.
Signs That Warrant Testing
Before pursuing a formal evaluation, it helps to know what you’re seeing. Dyslexia shows up differently depending on your child’s age, and recognizing specific patterns strengthens your case when requesting testing.
In preschool, the red flags are subtle. A child who can’t learn common nursery rhymes, struggles to remember letter names, or doesn’t recognize the letters in their own name may be showing early signs. Persistent “baby talk” and mispronouncing familiar words are also common. A family history of reading or spelling difficulties is one of the strongest predictors, since dyslexia runs in families.
By kindergarten and first grade, the signs become more concrete. Your child may not connect letters with their sounds, can’t sound out simple words like “cat” or “map,” or makes reading errors that have no connection to the letters on the page (saying “puppy” instead of “dog” because there’s a picture of a dog). Many children with dyslexia start complaining about how hard reading is or find ways to disappear when it’s time to read.
From second grade onward, reading is noticeably slow and awkward. Your child may make wild guesses at unfamiliar words rather than sounding them out, avoid reading aloud, and seem to lack any strategy for tackling new words. If these patterns have persisted for six months or more despite help at home or school, testing is a reasonable next step.
Requesting a School Evaluation
Under federal law (the Individuals with Disabilities Education Act), schools are required to identify and evaluate students suspected of having disabilities. This obligation is called “Child Find,” and it means you don’t need a doctor’s referral or a private diagnosis to get the process started. You simply need to make the request.
Put your request in writing. A letter or email to the school principal or special education coordinator stating that you suspect your child has a reading disability and are requesting a comprehensive evaluation creates a paper trail and starts the clock. Once the school receives your written consent to evaluate, federal law gives them 60 days to complete the evaluation (though some states have their own, sometimes shorter, timelines).
The school’s evaluation team will assess how your child’s reading difficulties affect their education. They’ll typically test phonological awareness, reading fluency, comprehension, and spelling. The goal is to determine whether your child qualifies for special education services through an Individualized Education Program (IEP) or accommodations through a 504 plan. This evaluation is completely free.
One important distinction: schools generally don’t use the word “dyslexia” in their findings. They’ll typically identify your child as having a “specific learning disability in reading.” The practical effect is the same for getting services, but if you want a formal clinical diagnosis of dyslexia on paper, you’ll likely need a private evaluation.
Getting a Private Evaluation
A private evaluation gives you a clinical diagnosis and often a more detailed picture of your child’s specific strengths and weaknesses. The professionals qualified to diagnose dyslexia are neuropsychologists and psychologists who specialize in learning disorders. Neuropsychologists focus specifically on the relationship between brain function and behavior, making them particularly well suited for this kind of assessment.
A comprehensive evaluation typically takes 4 to 8 hours, sometimes spread across multiple sessions. The evaluator will gather your child’s medical and family history, review previous school assessments, and administer a battery of standardized tests. These tests measure specific skills that underlie reading ability: how your child processes the sounds in language, how quickly they can retrieve and name familiar information, and how well they understand the rules of written English (like spelling patterns, punctuation, and letter combinations). Language comprehension and expression are often tested as well, since dyslexia can overlap with broader language processing differences.
The evaluator may also visit your child’s school, interview the teacher, and observe your child in the classroom. At the end, you’ll receive a written report with a diagnosis (if one applies), detailed scores, and recommendations for intervention and accommodations. This report becomes a powerful tool you can share with your child’s school.
What the Diagnosis Actually Requires
Clinically, dyslexia falls under the diagnosis of “specific learning disorder with impairment in reading.” To qualify, your child needs to meet four criteria. They must have had difficulty with reading accuracy, speed, or comprehension for at least six months despite receiving targeted help. Their reading skills must be substantially below what’s expected for their age, causing real problems in school or daily life. The difficulties must have started during school age (even if they weren’t fully recognized until later). And the reading problems can’t be better explained by something else, like vision or hearing issues, intellectual disability, or a lack of adequate instruction.
Diagnosis relies on a combination of standardized test scores, clinical observation, interviews, family history, and school reports. There’s no single test that produces a “positive” or “negative” result for dyslexia. It’s a pattern-based diagnosis that requires professional judgment.
School Testing vs. Private Testing
These two paths serve different purposes, and many families end up using both.
- School evaluations focus on educational impact. They determine whether your child needs specialized instruction and qualifies for an IEP. They’re free, legally mandated, and lead directly to school-based services. But they typically won’t produce a medical diagnosis of dyslexia.
- Private evaluations focus on cognitive and medical factors. They produce a formal diagnosis, offer more detailed testing, and give you a report you can use across settings (tutoring programs, standardized test accommodations, college disability services). But they cost money, often between $2,000 and $5,000 depending on your area.
The two systems don’t automatically defer to each other. Schools are required to consider a private evaluation, but they don’t have to adopt its findings. Even with a private dyslexia diagnosis in hand, the school will still determine independently whether your child needs special education services. Conversely, a school identification of a reading disability is valid for getting services at school but won’t serve as a clinical diagnosis outside that setting.
Paying for a Private Evaluation
Health insurance sometimes covers neuropsychological testing, but coverage varies widely. Insurers generally require documentation that the testing is medically necessary and will influence a treatment plan. Your pediatrician can help by providing a referral and documenting your child’s reading difficulties.
If insurance won’t cover it, some options can reduce costs. University training clinics affiliated with psychology or education programs often offer evaluations at reduced rates, conducted by supervised doctoral students. Some nonprofit organizations provide free or sliding-scale assessments. And in certain cases, if you disagree with the results of a school evaluation, you have the right to request an Independent Educational Evaluation at the school district’s expense.
Early Screening Options
If your child is in kindergarten or first grade and you’re not sure whether a full evaluation is warranted, screening tools can help. The Shaywitz DyslexiaScreen, developed through longitudinal research at Yale, is a five-minute assessment that helps teachers identify students who may have dyslexia. It’s based on teacher observations and a short series of ranked questions about phonological, linguistic, and academic performance. A growing number of states now mandate dyslexia screening in early grades, so your child’s school may already have screening protocols in place. Ask your child’s teacher or reading specialist what screening has been done and what the results showed.
Screening isn’t diagnosis. It identifies children who need further evaluation. But it can speed up the process considerably, giving you concrete data to reference when requesting a full assessment.
How to Move Forward Quickly
The single most effective step you can take right now is to write a dated letter to your child’s school requesting an evaluation for a suspected specific learning disability in reading. Be specific about what you’ve observed: the signs you’ve noticed, how long they’ve persisted, and any family history of reading difficulties. Keep a copy. This triggers the school’s legal obligation to respond.
At the same time, if you want a clinical diagnosis or suspect the school process will be slow, call your pediatrician for a referral to a neuropsychologist. Wait times for private evaluations can stretch to several months, so getting on a waitlist early gives you options. Running both processes in parallel is perfectly acceptable and gives your child the best chance of getting identified and supported without unnecessary delay.
