Signs of Dyslexia in Young Children

Dyslexia is a difficulty with the sounds inside words, and its first signs can appear as early as preschool: trouble with rhyming, trouble learning letter names and the sounds letters make, and, once reading is taught, trouble sounding out short words like cat or map. The International Dyslexia Association defines it as “a specific learning disability characterized by difficulties in word reading and/or spelling.” It is not a problem with seeing letters backwards.

A sign is a difficulty with sounds and words that lasts despite good teaching. One mistake at one age is not a sign. If you see the signs for your child’s age, tell their teacher what you are seeing, and ask about an evaluation if it does not change. This page describes signs worth raising. It does not diagnose, and no online test can.

Below are the signs at 4, 5, 6 and 7, how to tell dyslexia from a late start, when to ask for an evaluation, and how screening and testing work. If your child already has a diagnosis, the sections on school support, what helps, and practice at home are the ones for you.

What are the early signs of dyslexia at each age?

The early signs of dyslexia change with age, because what a child is being asked to do changes. Before reading is taught, the signs are about spoken words and letter names. Once it is taught, they are about linking letters to sounds and reading words. The signs below come from the Yale Center for Dyslexia & Creativity, led by Sally Shaywitz, and from the National Institute of Child Health and Human Development (NICHD). They are signs worth raising, not milestones every child must hit: for what is typical at each age, see reading milestones by age.

The check below asks about the signs for your child’s age, from what you have already noticed. Pick an age and it turns that age’s signs, the same ones described in the sections that follow, into questions you answer with “often”, “sometimes” or “not that I’ve noticed”, plus one question about family history. It ends with guidance in words: which signs came up, and whether they are worth raising with the teacher or worth asking about an evaluation. It is guidance, not a diagnosis, and your answers stay on the page.

Signs of dyslexia in a 4-year-old (preschool)

Signs of dyslexia in a 4-year-old are about spoken words and letter names, because most 4-year-olds are not reading yet. The Yale Center for Dyslexia & Creativity lists trouble learning common nursery rhymes such as “Jack and Jill,” not recognizing that cat, bat and rat rhyme, difficulty learning and remembering the names of letters, and being unable to recognize the letters in their own name. It also lists mispronouncing familiar words and “persistent ‘baby talk’.”

Family history matters most at this age, because the other signs are faint. Yale lists a family history of reading or spelling difficulty as a preschool sign in its own right.

Many 4-year-olds still swap one speech sound for another, and on its own that is speech development, not dyslexia. The phonological processes chart shows the age at which each common pattern usually stops. If speech itself is the worry, a speech-language pathologist is the right person to ask.

Signs of dyslexia in a 5-year-old (kindergarten)

Signs of dyslexia in a 5-year-old show up when letters and sounds are taught. The Yale Center for Dyslexia & Creativity lists a kindergartner who “does not associate letters with sounds,” so the letter b and the sound /b/ stay unconnected after weeks of teaching. Yale also lists a child who “does not understand that words come apart”: they cannot hear that sun begins with /s/, or split a short word into its sounds. A third sign carries over from preschool, learning letter names and sounds and then losing them again.

What makes these signs rather than a slow start is that they last after the skill has been taught. A 5-year-old who has not yet been shown letter sounds is not showing a sign by not knowing them. Our guide to teaching letter sounds and our page on hearing the sounds in words cover the two skills involved. The kindergarten readiness check is practice and a readiness picture, not a dyslexia check.

Signs of dyslexia in a 6-year-old (first grade)

Signs of dyslexia in a 6-year-old center on sounding out words. The Yale Center for Dyslexia & Creativity lists a first grader who “cannot sound out simple words like cat, map, nap,” and who makes “reading errors that show no connection to sounds,” with its own example: reading “puppy” for the word dog. Yale adds a child who complains about how hard reading is. The NICHD lists “problems sounding out words” and “poor spelling” among the symptoms of reading disorders.

Guessing from the picture or the first letter is the habit to watch. A 6-year-old who cannot sound a word out says a word that fits the story instead. That habit is common in children who are not dyslexic too, and it responds to teaching, so the sign is the guessing that remains after a month or more of practice sounding words out. Our pages on a child who cannot sound out words and a child who guesses at words cover both.

Signs of dyslexia in a 7-year-old (second grade)

Signs of dyslexia in a 7-year-old are about slow, effortful reading and poor spelling. For second grade onward, the Yale Center for Dyslexia & Creativity lists reading that “is slow and awkward,” “trouble reading unfamiliar words, often making wild guesses,” avoiding reading out loud, and poor spelling. It also lists speech signs: searching for a word and settling for “stuff” or “thing,” and confusing words that sound alike.

The sign that ties these together is a gap between how well a child talks and how well they read. Yale defines dyslexia as “an unexpected difficulty in learning to read,” and lists strengths such as a large vocabulary and “excellent comprehension of stories read or told.” A 7-year-old who follows a chapter book read aloud with ease, yet reads a page of it slowly and with many errors, fits that pattern.

Letter reversals count as a sign at 7 in one form only. Reversals are still common in second grade, and they matter when they come alongside these reading and spelling difficulties rather than on their own.

Is it dyslexia, or is my child just a late reader?

Most children who are slow to start reading are not dyslexic. They are missing a skill that has not been taught or practiced enough, and the gap closes with teaching. In a study by Frank Vellutino and colleagues, half of a group of children at risk of reading difficulty got small-group help two to three times a week in kindergarten, and the researchers found that help in kindergarten, or in kindergarten and first grade, prevented early and long-term reading difficulty “in most at-risk children.” Our guide to what “behind in reading” means covers the skill-gap case in full.

Three things separate dyslexia from a late start:

• It lasts despite good teaching. The gap does not close after a month or more of the right practice, at school and at home.
• It is about sounds and words. The difficulty is linking letters to sounds and reading words, not interest or attention.
• It is unexpected. Reading is out of step with how the child talks, understands stories, and learns other things.

A family history makes dyslexia more likely. A review of 95 publications by psychologists Snowling and Melby-Lervåg found that children with a family history of dyslexia were, as a group, slower to develop language as toddlers and had more difficulty with the sound structure of words in preschool. Family history raises the chance; it does not decide it.

Dyslexia and ADHD are different difficulties that often occur together. The International Dyslexia Association calls them “distinct conditions that frequently overlap,” which “do not cause each other.” Reading is so demanding for a dyslexic child that their attention can flag, and that can look like ADHD. The reading differs, though: in IDA’s description, a dyslexic reader misreads words, while a reader with ADHD is more likely to lose their place or leave off endings. IDA also notes that both conditions run in families. An evaluation can look at both.

Dyslexia is not a vision problem and not a measure of intelligence. The International Dyslexia Association describes the problems as “language-based, not visual and not related to cognitive skills or intelligence.” A child with dyslexia is not lazy and is not seeing letters backwards.

Is mixing up b and d a sign of dyslexia?

Mixing up b and d is not, on its own, a sign of dyslexia. Rebecca Treiman and colleagues followed 130 children from age 5 or 6, and the ones who later became weaker readers were “no more likely to make reversal errors” than the others. Reversals are common into second grade. What matters is reversals that last alongside trouble with sounds and words. Our guide to why kids write letters backwards has the full answer.

When should you ask about a dyslexia evaluation?

Ask about an evaluation when the signs for your child’s age are still there after a month or more of the right practice, at school and at home. Ask sooner if several signs show up together, or if there is a family history of dyslexia and the early signs are there. A single sign at a single age is a reason to practice that skill and watch, not a reason to test.

Earlier is easier, because the gap is visible early. The Connecticut Longitudinal Study, which followed 414 children from first grade to twelfth, found the reading gap between dyslexic and typical readers “evident as early as first grade.” Its authors, Emilio Ferrer and colleagues, wrote that this supports early identification and intervention, starting as early as kindergarten. The International Dyslexia Association makes the same point: extra teaching works best begun in kindergarten or first grade, “when the gap is small.”

Start with the class teacher, in writing if you want a record. The teacher sees your child beside 20 or more others of the same age and can say whether what you see stands out. You can also ask the school for an evaluation in writing at any time, and the school cannot make your child finish a round of extra support first. The federal rules and the timeline are in our section on how an evaluation starts.

A pediatrician helps rule other things out, not diagnose dyslexia. The federal special education regulations, at 34 CFR 300.8, define a specific learning disability so that it excludes problems “primarily the result of visual, hearing, or motor disabilities,” so a hearing and vision check is worth having. The International Dyslexia Association notes that “evaluation by a medical doctor is not required” to identify dyslexia.

Do schools screen for dyslexia in kindergarten?

Schools in many states screen every kindergartner for reading risk, because state law requires it. According to the National Center on Improving Literacy, a federally funded center, “50 states have passed legislation related to dyslexia” as of its 2026 report. What each state requires differs, including whether and when children are screened, and the center’s State of Dyslexia site shows each state’s law.

A dyslexia screener is a short check given to the whole class, and the National Center on Improving Literacy recommends giving it several times a year. It looks at the early skills reading is built on: knowing letters and their sounds, hearing the sounds in spoken words, and reading short words. Many schools use DIBELS, which our guide to DIBELS scores explains subtest by subtest. NWEA’s MAP Reading Fluency test has a dyslexia screener built in for kindergarten through third grade, and our guide to MAP scores explains what its “Flagged” result means.

A screening flag is a reason to look closer and watch progress, not a diagnosis. Screeners are built to catch as many at-risk children as they can, which means some children are flagged who turn out to be fine. The National Center on Improving Literacy is direct about it in its screening report: “It is not appropriate to use screening results to formally diagnose whether an individual actually has dyslexia.”

A dyslexia screening and a dyslexia evaluation answer different questions. A screening asks “is this child at risk?” It is brief, is given to every child in the class, and sorts children into those to watch and those not to. An evaluation asks “what is going on, and why?” It is given to one child by a qualified professional, and it can identify dyslexia. The National Center on Improving Literacy describes diagnosis as a “more comprehensive, time consuming” process, meant for children whom screening flagged, who did not respond to early reading help, or both.

How is a child tested for dyslexia?

A dyslexia evaluation tests the skills dyslexia affects, one at a time. The International Dyslexia Association lists the areas: hearing and working with the sounds in spoken words (phonological awareness), memory for sounds and words, rapid naming of objects, colors, digits or letters, vocabulary, phonics, decoding real and made-up words, oral reading fluency, spelling, and writing. The NICHD says providers also consider “family history, a child’s history of response to instruction, and other assessments.” The evaluator collects the child’s birth, family, developmental, and speech and language history as well, in the International Dyslexia Association’s account, which is how other explanations get ruled out.

Who can diagnose dyslexia is set by training, not by a medical license. The International Dyslexia Association describes evaluation as individual testing “most often provided by a team of qualified professionals,” with graduate degrees in education, reading, speech-language pathology, school psychology, psychology or neuropsychology. In a school, that team often includes the school psychologist. Ask your school or your state department of education who evaluates for dyslexia where you live.

A school report may say “specific learning disability” rather than “dyslexia.” That is the category in the federal regulations, and 34 CFR 300.8 names dyslexia among its examples. In a 2015 letter, the Department of Education’s Office of Special Education Programs says there is “nothing in the IDEA that would prohibit the use of the terms dyslexia” in an evaluation, an eligibility decision or an IEP. You can ask for the word to be used.

A school evaluation is free, and a private one is paid for by the family. The Center for Parent Information and Resources (CPIR), funded by the Department of Education, says of the school’s evaluation: “This evaluation is free of charge.” A school evaluation also decides whether your child qualifies for formal support there. If you get a private evaluation, the federal rule on independent evaluations, 34 CFR 300.502, says the school must consider its results, if it meets the school’s criteria, but the school does not have to adopt them. The same rule gives you the right to an independent evaluation at public expense if you disagree with the school’s.

No online or at-home test can diagnose dyslexia, and the check on this page does not try to. It is guidance on what to raise and with whom. What you can usefully do at home is write down what you see, with dates and real examples: the word your child read as something else, the way they spelled a word on Monday and on Thursday, the rhyme they could not hear. Notes like that give a teacher or an evaluator something concrete to start from.

What support can a child with dyslexia get at school?

A child with dyslexia can get support at school through an IEP or a 504 plan. A child found eligible under the federal special education law gets an Individualized Education Program (IEP), a written plan for the specially designed teaching and support the school will provide. A child who does not need special teaching but needs changes to how they learn or are tested may get a Section 504 plan instead. The International Dyslexia Association puts the difference this way: for a child diagnosed with dyslexia, an IEP “provides both remediation and accommodations,” while a 504 plan provides accommodations and “does not specify the provision of direct specially designed instruction.”

For a young child, the teaching matters more than the accommodations. A 6-year-old who is not yet reading needs to be taught to read, so ask what the teaching is, how often it happens, and who delivers it. If the school turns down a request, the federal prior notice rule, 34 CFR 300.503, requires it to tell you in writing what it refused and why.

Many schools also run tiered small-group reading help, sometimes called MTSS or RTI, for any child who is struggling, with or without a diagnosis.

What helps a child with dyslexia learn to read?

What helps a child with dyslexia learn to read is structured literacy: explicit, systematic teaching of sounds, letters and how words are built. The International Dyslexia Association says: “What does work is Structured Literacy, which prepares students to decode words in an explicit and systematic manner.” It describes that teaching as starting with the sounds in spoken words, then the letters that spell them, then syllables and word parts, taught in order, each step built on the last, and nothing left for the child to work out alone. Orton-Gillingham is one well-known approach built on these principles, and our guide to the science of reading explains how the two relate.

Help works best begun early and delivered by someone trained. The International Dyslexia Association describes the teacher’s job as continuous, individual adjustment to what the child has and has not mastered, which takes training. That can be a reading specialist, a tutor trained in a structured literacy method, or the school’s own intervention. When a school or tutor offers help, ask whether it teaches sounds and letters explicitly and in a set order.

Vision therapy and colored lenses are not treatments for dyslexia. The American Academy of Pediatrics, in a joint statement with the American Academy of Ophthalmology and two pediatric eye-care associations, says that “vision problems are not the cause of primary dyslexia,” and that eye exercises, behavioral vision therapy, and special tinted filters or lenses “are not endorsed and should not be recommended.”

Dyslexia is lifelong, and the right teaching still works. The International Dyslexia Association says children with dyslexia “do not outgrow their disability,” but “they can learn to adapt and improve their weak skills,” and that children identified and taught early are more likely to overcome their difficulties.

An app is practice, not intervention. No app replaces structured literacy taught by a trained person. What an app can add is repetition of what is being taught. Our guide to choosing a reading app covers what to look for. If spelling is the hardest part, why spelling is hard for some kids covers the techniques that help at home.

How can you help a child with dyslexia at home?

The most useful help at home is a few minutes a day on the same sounds and words your child is being taught at school or by a tutor. Practice what is already being taught rather than starting a second program alongside it. Ask the teacher or tutor what they are working on this week and practice that. Short sound games and blending practice cover the two skills most often involved, and teaching your child to read at home sets out a daily routine.

Keep reading aloud to your child, and count audiobooks. A child with dyslexia often understands far more than they can read. The Yale Center for Dyslexia & Creativity lists “excellent comprehension of stories read or told” among their strengths. Reading aloud keeps vocabulary and a love of stories growing while reading itself catches up.

Protect your child’s confidence. Yale lists “low self-esteem that may not be immediately visible” among the signs from second grade on. Describe dyslexia as something their brain finds hard, not something they are bad at, and keep practice short so it ends before frustration does. If practice has already turned into a fight, what to do when your child resists reading practice starts there.
