Spotting Dyslexia Early: What Parents and Teachers Should Know Before Kindergarten

A child who mixes up "busgetti" for "spaghetti," struggles to think of a word that rhymes with "cat," or still can't recite the alphabet at four isn't necessarily behind — plenty of young children move through these stages without issue. But for some children, these small stumbles are the earliest visible signs of dyslexia, showing up years before a report card ever mentions "reading difficulty." Knowing what to watch for in the preschool years can make the difference between a child who gets support early and one who spends years quietly struggling before anyone understands why.

How Common Is Dyslexia, Really?

Dyslexia is far more common than most people assume. A large systematic review and meta-analysis of primary school children worldwide found a pooled prevalence of roughly 7% for developmental dyslexia, with rates notably higher in boys than in girls (Yang et al., 2022). Other major estimates place the range even broader — commonly cited as somewhere between 5% and 17% of the population, depending on the criteria used to define and diagnose it (Yang et al., 2022). In practical terms, that means most classrooms of 20-plus students likely include at least one or two children with some degree of dyslexia, whether or not it's been identified yet.

Common Early Signs in Young Children

Reputable medical and educational organizations consistently point to a similar cluster of early signs, well before formal reading instruction begins. According to Mayo Clinic, signs that a young child may be at risk of dyslexia include late talking, learning new words slowly, reversing sounds within words, and difficulty learning nursery rhymes or rhyming games (Mayo Clinic, n.d.).

Cleveland Clinic outlines a similar early picture for preschoolers ages three to five, noting that parents might observe difficulty learning or recognizing letters, trouble finding words that rhyme, and mixing up words that sound alike, such as saying "cat" instead of "cap" (Cleveland Clinic, n.d.).

The Child Mind Institute adds a few additional preschool-age indicators worth watching for, including a speech delay, trouble following multi-step directions, and difficulty telling a simple story back in the correct order (Child Mind Institute, n.d.). None of these signs alone confirms dyslexia — many children show one or two of them briefly and go on to read without any trouble. What tends to matter more is a pattern: several of these signs appearing together and persisting past the age most peers have moved beyond them.

The Montessori Connection: Watching Without Rushing

Long before "early screening" was a formal educational practice, Maria Montessori built her entire approach around close, patient observation of each child's individual pace — precisely the mindset early dyslexia screening requires. As she put it:

"The spontaneous urge towards development, which is within the child, dictates its own pace." — Maria Montessori, Maria Montessori Speaks to Parents

This isn't a call to ignore warning signs — it's a reminder of how to watch for them: without panic, without comparison to a rigid timeline, and without conflating a child's natural pace with a red flag prematurely. A Montessori classroom's multisensory reading materials — sandpaper letters a child traces with a finger while hearing the sound aloud, movable alphabets that separate the physical act of forming a word from the fine-motor demands of handwriting — happen to align closely with the same phonological, hands-on approaches speech and reading specialists recommend for children at risk of dyslexia. The environment doesn't diagnose a child, but it does create daily, low-pressure opportunities for a trained observer to notice when a child's letter-sound connections aren't forming the way they typically do at that age.

Montessori was equally clear that the goal was never to rush a child past where they naturally were:

"One test of the correctness of educational procedure is the happiness of the child." — Maria Montessori, The Absorbent Mind

For a child showing early signs of dyslexia, that principle matters enormously. The goal of noticing early signs isn't to label or pressure a young child — it's to get them the right kind of support before frustration and anxiety attach themselves to reading, which can happen quickly once a child starts sensing they're "behind."

What to Do If You Notice These Signs

If several of these patterns show up together and persist, the next step isn't to diagnose at home — it's to raise it with your child's pediatrician, teacher, or a licensed speech-language pathologist. Mayo Clinic recommends talking with a healthcare provider if a child's reading level falls below what's expected for their age, or if several of these early signs are present together (Mayo Clinic, n.d.). Early evaluation opens the door to early intervention, and research consistently shows that intervening earlier tends to produce better long-term outcomes than waiting until a child has fallen further behind in elementary school.

The Takeaway

Dyslexia is common, identifiable well before kindergarten in many cases, and — with early, informed support — very manageable. The role of parents and teachers isn't to diagnose from a checklist, but to watch closely, stay patient, and know when a pattern of signs is worth a professional conversation. That combination of close observation and unhurried patience is, fittingly, exactly what Montessori asked of every adult in a child's life a century ago.
