Dyslexia and English Language Learners: How to Tell the Difference
Last updated: August 9, 2026 · Reviewed by the Dyslexia Evaluations LLC clinical team
Is it dyslexia or just learning English?
When a bilingual child struggles with reading, it can be genuinely hard to tell whether the problem is dyslexia or the normal process of learning English as a second language. The short answer: dyslexia shows up in every language a child speaks, while second-language struggles usually improve with time and exposure. The two can also happen together.
If your child is learning English as a new language and also having a hard time with reading, you are asking exactly the right question. Many parents worry, and many teachers hesitate, because the signs overlap so much. A child who mixes up words, reads slowly, or struggles to spell might be showing signs of dyslexia, or might simply be at an early stage of building a second language.
This guide walks through the real differences, what to look for, and how a proper evaluation sorts it out. It is written for parents of children roughly ages 4 to 15 who speak more than one language at home or at school. Nothing here is a diagnosis. It is meant to help you decide whether a closer look makes sense.
What is dyslexia, and how is it different from learning a second language?
Dyslexia is a brain-based difference in how a person processes the sounds and structure of language, which makes reading and spelling harder than expected. Learning a second language, by contrast, is a normal developmental process. A dyslexic brain works differently no matter which language it is reading; a second-language learner simply needs more time and input.
Dyslexia is not about intelligence, effort, or how much a child was read to. According to the International Dyslexia Association, as many as 15 to 20 percent of people show some of the symptoms of dyslexia, including slow reading, weak spelling, and trouble with word recall. That number holds across languages and cultures, which is one reason experts say dyslexia is not caused by being bilingual.
English language learners (often called ELLs, or ESL students) are going through something different. They are decoding a new sound system, a new vocabulary, and often a new alphabet at the same time. That naturally slows reading down for a while. To understand the underlying condition better, it helps to read our plain-language overview of what dyslexia is.
The key idea to hold onto: being an English learner does not cause dyslexia, and dyslexia is not a phase a child grows out of. One fades with practice. The other needs targeted support.
Why do dyslexia and English language learning look so similar?
Both dyslexia and second-language learning can produce slow reading, spelling errors, trouble sounding out words, and a limited English vocabulary. Because the surface behaviors overlap so heavily, teachers and parents often cannot tell them apart by watching a child read in English alone. The overlap is real, and it is the main reason bilingual children are so often misjudged.
Here are the behaviors the two situations share:
Slow, effortful reading that lags behind classmates.
Spelling that does not match the spoken word, often spelled the way it sounds.
Trouble sounding out new words or blending letters into words.
Mixing up similar-looking or similar-sounding words.
A smaller English vocabulary than monolingual peers.
Avoiding reading aloud or getting frustrated with reading tasks.
Any one of these, on its own, could come from either cause. That is why single behaviors are never enough to draw a conclusion. What matters is the pattern, the timeline, and whether the same difficulties show up in the child's first language too. A quick look at what dyslexia actually looks like day to day can help you compare notes with what you see at home.
What signs point more toward dyslexia than language learning?
Certain patterns lean more toward dyslexia. The strongest clue is when a child struggles with reading and spelling in their home language too, not only in English. Difficulty hearing and playing with individual sounds, a family history of reading struggles, and trouble that persists despite good teaching all point toward a language-processing difference rather than a language-exposure gap.
Watch for these signals:
Reading and spelling difficulties in the child's first language. If a child who has spoken Spanish, Arabic, or Hmong at home for years still cannot read simple words in that language, exposure is not the missing piece.
Trouble with the sounds of language (phonological awareness). Struggling to rhyme, clap syllables, or notice that "cat" and "cup" start with the same sound can appear regardless of language and is a classic dyslexia signal.
A family history of dyslexia or reading trouble. Dyslexia runs in families. If a parent or sibling struggled to read, the odds rise. Our article on whether dyslexia is genetic explains the family-risk research.
Very slow progress despite strong instruction. Most English learners make steady gains once they get good teaching and time. When a child gets solid support and still stalls, that gap is worth investigating.
Trouble recalling common words quickly, even familiar ones in either language.
No single item confirms anything. But when several of these cluster together, especially difficulty in the home language, a professional look is warranted.
What signs point more toward normal second-language learning?
Some patterns are reassuring and typical of a child who is simply building English. If your child reads well in their first language, is steadily improving in English month over month, and mainly struggles with vocabulary and comprehension rather than sounding out words, the difficulty is more likely tied to language exposure than to dyslexia.
Encouraging signs include:
Strong reading in the home language. A child who reads fluently in their first language usually has intact language-processing skills.
Steady, visible improvement. English learners typically make clear month-to-month gains in reading and speaking once they are immersed and supported.
Struggles centered on meaning, not decoding. Trouble understanding a passage because of unfamiliar vocabulary is different from being unable to sound the words out at all.
Good phonological awareness. A child who can rhyme, segment sounds, and play with words in either language is showing a healthy foundation.
Errors that make sense for a new-language learner, such as applying first-language spelling rules to English.
These patterns suggest a child on a normal path who mostly needs time, rich language input, and patience. Even so, if you feel unsure, a free screening can give you peace of mind without any cost or commitment.
How can teachers and parents tell the difference?
The most reliable way to separate dyslexia from second-language learning is to look at reading in both languages, track progress over time, and use a proper evaluation rather than a single classroom observation. Parents and teachers each hold half the picture, so sharing what you each see is powerful.
Look at both languages
If possible, notice how your child reads and speaks in the home language. Difficulty that appears in both languages is a stronger signal of dyslexia than trouble in English alone. Difficulty only in English points more toward the normal work of learning a new language.
Track progress over months, not days
English learners generally show steady gains with good teaching. Keep informal notes: Is reading getting smoother? Is the child recognizing more words? Steady growth is reassuring. A long plateau despite good support is a reason to dig deeper.
Share notes between home and school
Teachers see your child among peers; you see them relaxed at home in their first language. Comparing observations, such as our parent's checklist of dyslexia signs, helps you spot patterns neither of you would catch alone.
Do not wait for "good enough" English
A common and costly myth is that a child must master English before anyone can check for dyslexia. Waiting years for that can delay real help. Skilled evaluators can assess for dyslexia in bilingual children without waiting for full English fluency.
Can a child be an English language learner and have dyslexia?
Yes. A child can absolutely be learning English as a second language and also have dyslexia at the same time. These are two separate things, and one does not rule out the other. In fact, bilingual children with dyslexia are among the most likely to be overlooked, because their reading struggles get explained away as "just the language."
This is the situation that worries specialists the most. When a bilingual child struggles, the difficulty is often blamed entirely on English learning, so the underlying dyslexia goes unidentified for years. The reverse also happens: a child's normal second-language process gets mislabeled as a disorder. Both mistakes delay the right kind of support.
The healthiest mindset is to hold both possibilities open. Ask: Does this look like language exposure, a processing difference, or both? You do not have to answer that alone. A structured dyslexia screening is designed to help sort exactly this out, and it is free. If the screening raises flags, a full evaluation looks deeper.
How is dyslexia identified in bilingual and multilingual children?
Identifying dyslexia in a bilingual child means gathering the whole picture: how the child reads in each language, their history, their phonological (sound) skills, and how they respond to good teaching. A quality evaluation does not rely on a single English reading test, which can unfairly penalize a new English speaker.
A thoughtful process usually includes:
A developmental and family history, including which languages are spoken at home and any relatives who struggled with reading.
Assessment of core skills that cut across languages, especially phonological awareness, rapid naming, and working memory, which are less dependent on English vocabulary.
A look at reading in the home language where possible.
Attention to how the child responds to instruction over time, drawing on the ideas behind response to intervention.

What can parents do right now?
You do not need to have all the answers to take a helpful first step. Start by observing your child in both languages, jotting down what you notice, and taking a free screening. These small actions cost nothing and give you real information instead of worry.
Here is a simple plan:
Watch reading in both languages for a couple of weeks and note where the struggle shows up.
Talk with the teacher and compare what each of you sees.
Take a free screening to get a structured read on whether a fuller look is worth it.
Keep reading together in whichever language feels comfortable, because language and vocabulary in any language support reading overall.
Act sooner rather than later. Early support changes outcomes, and waiting for "perfect" English is not necessary.
Whatever the cause turns out to be, your child benefits from your attention. Confusion is not failure. It is the starting point of getting the right help.
Frequently Asked Questions
Does being bilingual cause dyslexia?
No. Being bilingual does not cause dyslexia and does not make it worse. Dyslexia is a brain-based difference in language processing that a child is born with. Bilingual children develop dyslexia at the same rates as anyone else. Learning two languages is good for the brain, not a risk factor.
Should we wait until my child speaks English fluently to check for dyslexia?
Generally, no. Waiting for full English fluency can delay help for years. Skilled evaluators can assess bilingual children by looking at skills that cut across languages, such as sound awareness and word recall, and by considering reading in the home language. Early action tends to lead to better outcomes.
My child reads fine in our home language but struggles in English. Is that dyslexia?
That pattern leans away from dyslexia and toward normal second-language learning, because strong reading in the first language suggests intact language processing. It is not a guarantee either way, though. If English reading stalls for a long time despite good teaching, a screening can help you decide whether to look closer.
Can one evaluation cover a bilingual child fairly?
A good evaluation is designed to be fair to bilingual children by measuring skills that do not depend heavily on English vocabulary and by factoring in language history. It should never rest on a single English-only reading test. Ask any evaluator how they account for a child's language background.
Is the screening really free, and what does the full evaluation cost?
Yes, the dyslexia screening is completely free and takes only a few minutes. If the screening suggests a closer look is warranted, a comprehensive evaluation is $2,200, available in Madison, Wisconsin, and virtually nationwide. There is no obligation to move from the screening to the evaluation.
