There's a sentence multilingual parents hear that sounds reasonable and costs children years: "Let's give her more time — she's still learning English." Sometimes it's true. Reading in a second language genuinely does develop along its own timeline, and flagging every English learner who reads haltingly would be its own kind of error. But dyslexia occurs in every language and every writing system, at roughly similar rates — and a child with dyslexia who is also learning English has two separate things going on, only one of which time will fix. Schools that can't tell the difference default to waiting, which is why English learners are among the most under-identified groups in special education. Here's how the difference actually shows, and what families can do about it.
Does dyslexia look the same in every language?
The underlying difference is the same — the brain's phonological machinery, the part that notices and manipulates the sounds inside words, works less automatically. How visibly that surfaces depends on the writing system. In "transparent" orthographies like Spanish, Italian, or Finnish, where letters map to sounds consistently, children with dyslexia usually learn to read words accurately but slowly — the difficulty shows up as labored, dysfluent reading rather than dramatic errors. English, with its famously inconsistent spellings, exposes the weakness more brutally and earlier. This matters practically: a child who "learned to read fine" in Spanish and is now sinking in English may not be a language-acquisition story. The Spanish reading may have been slow and effortful all along — transparent orthographies hide dyslexia; English unmasks it.
Why do English learners with dyslexia get missed?
The International Dyslexia Association's guidance on English learners names the failure mode directly: schools attribute reading and writing difficulties to the student's status as an English learner, even when the child also shows clear characteristics of dyslexia. The wait is well-intentioned — nobody wants to over-identify children as disabled because of a language difference, and that over-identification has a real, ugly history. But the modern pendulum swung to under-identification: the English learner who struggles gets "more time" year after year, while a monolingual classmate with the same profile gets evaluated. Federal law is unambiguous here — a child cannot be found eligible for special education because of limited English proficiency, but limited English proficiency also cannot be a reason to refuse evaluation to a child who needs one.
How can you tell dyslexia from normal second-language development?
No single sign settles it, but the pattern is readable:
- Trouble in the first language too. Dyslexia travels with the child. Ask: did learning to read the home language come slowly? Are the sounds and rhymes of the home language hard to play with? A parent is the expert witness here.
- The right comparison group. Compare the child to true peers — other students who arrived with similar language backgrounds and schooling — not to native speakers. Lagging far behind fellow English learners is a flag, not a language stage.
- Phonological signs that cross languages. Difficulty rhyming, blending, and pulling words apart into sounds; trouble connecting letters to sounds even after explicit teaching; effortful, inaccurate decoding of even simple new words. Vocabulary gaps are a language-learning story; sound-level struggles usually aren't.
- Family history. Dyslexia is strongly heritable in every language. A parent or sibling who struggled to read is the same risk factor in Karachi, Guadalajara, or Cleveland.
What should families ask the school for?
An evaluation that takes both languages seriously. That means assessment by someone qualified in the child's language where possible — or with a trained interpreter and appropriately normed tools where not — looking at phonological awareness, rapid naming, and decoding in both languages, alongside the child's language-acquisition history. Put the request in writing, dated, and say explicitly that you are requesting evaluation for a suspected reading disability, not language support — the two systems are different doors. If you're told "we don't evaluate English learners until they're fluent," ask for that policy in writing; it isn't lawful as a blanket rule. Our parent toolbox has the letter, and the signs-by-age guide helps you document what you see in either language. Screening systems are slowly catching up — California's new universal screening was designed with English learners specifically in mind (our coverage).
What mistakes should families and schools avoid?
- Dropping the home language. Bilingualism does not cause or worsen dyslexia, and abandoning the home language costs family connection while buying nothing. Intervention works alongside two languages.
- Accepting "wait until English is fluent." Fluency can take five to seven years. A child with dyslexia can't lose those years — and the intervention that helps works on skills beneath either language.
- Confusing accent or vocabulary with decoding. A child can have a rich accent and thin English vocabulary and decode beautifully — or speak fluent conversational English and be unable to sound out lap. Only the second pattern points to dyslexia.
- Testing only in English. An English-only evaluation of a bilingual child measures English exposure as much as reading ability. Push for both languages on the record.
Frequently asked questions
Can a child have dyslexia in one language but not another? Not really — the underlying phonological difference travels with the child. But it can be far more visible in English than in consistent orthographies like Spanish, where dyslexia tends to show as slow, effortful reading rather than frequent errors. A child who reads a transparent language slowly and English poorly likely has one condition, not a language problem.
Should we stop speaking our home language to help our dyslexic child? No. Research is consistent that bilingualism doesn't cause or worsen dyslexia, and the home language carries family, identity, and a vocabulary foundation that supports learning. Keep both languages; add structured-literacy intervention.
Can a school refuse to evaluate my child until their English improves? Not as a blanket policy. If a disability is suspected, evaluation rights under federal law apply regardless of English proficiency, and the evaluation must account for the child's language background. Make the request in writing and ask for any refusal in writing too.
