How Can We Identify Dyslexia in Bilingual and ELL Students?

Published April 27th, 2026

Identifying dyslexia in bilingual and English Language Learner (ELL) students presents a unique and complex challenge. These students often experience typical language acquisition hurdles that can closely resemble dyslexia symptoms, leading to underidentification or misdiagnosis. This overlap means that many multilingual learners with dyslexia remain invisible within education systems, missing out on the early, targeted support they need to thrive.

Accurate and timely identification is crucial to ensure equitable literacy outcomes for these students. Without specialized knowledge and tools, educators and families may struggle to distinguish between normal language learning processes and persistent reading difficulties rooted in dyslexia. Our approach offers a clear, step-by-step guide designed to help navigate these complexities with confidence and care. By focusing on evidence-based strategies and multilingual assessment perspectives, we aim to empower those who support bilingual and ELL learners to recognize dyslexia early and respond effectively. 

Understanding Dyslexia Within the Context of Bilingualism and Second Language Learning

Problem: Dyslexia often gets confused with normal second language struggles, so multilingual students stay invisible or are mislabeled.

Solution: We start by separating what dyslexia is from what it is not, and then place it inside the realities of bilingual and ELL learning.

Dyslexia is a neurobiological difference in how the brain processes spoken and written language. It affects accurate and fluent word reading, spelling, and decoding. It is not caused by low intelligence, poor teaching, or speaking more than one language.

For bilingual and ELL students, dyslexia usually shows up in all their languages, though it may look different in each. A child may read slowly in English and also struggle to sound out words in Spanish, even if they speak Spanish fluently at home. The reading profile follows the student across languages, not just in the language of instruction.

How Language Learning Can Mimic Dyslexia

Typical second language development often includes:

• Limited vocabulary and use of simple sentence structures
• Grammar errors that match patterns from the first language
• Slower reading in the new language while decoding in the first language stays solid
• Difficulty understanding texts with unfamiliar cultural references

These are language proficiency issues. When students gain exposure and instruction, these skills usually improve in a steady way.

How Dyslexia Cuts Across Languages

In contrast, dyslexia affects the building blocks of reading that all alphabetic languages share:

• Linking sounds to letters and letter patterns
• Holding and manipulating sounds in words (phonological awareness)
• Reading single words accurately and quickly, even common words
• Spelling words the way they sound, in any language they write

These difficulties tend to persist even with good instruction and exposure, and they appear in both the first and additional languages, though sometimes more strongly in the less familiar language.

The Role of Language Structure and Exposure

Language structure shapes how dyslexia shows up. In a language with regular spelling patterns, a student with dyslexia may read accurately but very slowly, needing extra effort for each word. In a less consistent orthography, the same student may show both inaccuracy and slow reading. Limited literacy exposure in any language can add another layer, making it harder to tell whether the problem is lack of opportunity or an underlying reading difference.

When we keep these distinctions in view, we are better prepared to tell the difference between expected second language challenges and the deeper, persistent patterns that signal dyslexia in multilingual learners. 

Recognizing Early Warning Signs of Dyslexia in Bilingual and ELL Students

Problem: Early signs of dyslexia in multilingual learners often blend into the background of normal second language development, so we miss the pattern until reading demands have already escalated.

Solution: We watch for consistent, cross-language warning signs in phonological processing, decoding, spelling, and fluency, and we track how those patterns behave over time.

Language-Neutral Warning Signs to Watch

Some indicators show up across alphabetic languages, no matter which language is stronger:

• Persistent difficulty with rhyming and sound play in early years: trouble noticing that words rhyme, generating rhymes, or clapping syllables in either language.
• Slow, effortful learning of letter - sound links: needing many more repetitions to connect letters and letter groups with their sounds, or confusing them day to day.
• Weak phonological awareness: difficulty pulling apart sounds in words, blending sounds into words, or changing one sound to make a new word.
• Decoding that does not become smoother: sounding out the same word repeatedly as if it were new, or losing the word from one line to the next.
• Single-word reading much weaker than listening comprehension: understanding rich stories or discussions when read aloud, but stumbling on basic printed words.
• Spelling that stays phonetic or unstable: writing words several different ways, omitting sounds, or reversing sound order, even for familiar words.
• Reading fluency that lags far behind peers: very slow, choppy oral reading with frequent pauses to decode, long after initial instruction.

Patterns Specific to Bilingual and ELL Learners

For multilingual learners with specific learning disabilities, the warning signs often appear in more than one language, though not always with the same intensity. We look for:

• Inconsistent performance across languages: strong oral vocabulary in the home language but similar decoding and spelling struggles in both languages.
• Plateaus after the usual adjustment period: initial slow progress that does not pick up even after several years of exposure and instruction in the language of schooling.
• Difficulty transferring skills between languages: learning a decoding pattern in one language but not applying the same principle when it appears in the other language.
• Ongoing confusion with common function words (articles, prepositions, pronouns) in print, even when they are used accurately in speech.
• Reading avoidance across languages: reluctance to read aloud or choose reading tasks in any language, not only in the newer one.

Observing Patterns Over Time at School and Home

We do not rely on a single bad day or one weak assessment. Instead, we build a simple record of what we see across settings:

• Use parallel tasks in both languages when possible: note how the student handles rhyming, sound blending, or reading word lists in each language.
• Track response to focused instruction: after several weeks of targeted phonological or decoding support, record whether accuracy and speed improve or remain stuck.
• Notice gaps between oral language and print: a student who tells complex stories but cannot read or spell basic words raises a different concern than one with limited vocabulary.
• Coordinate school and home observations: caregivers can note difficulties with remembering letter names, reading simple labels, or learning common sight words in any language used at home.

When these kinds of difficulties cluster together, appear in more than one language, and persist despite systematic teaching, we move from assuming a normal ELL learning curve to considering targeted dyslexia assessment. 

Step-by-Step Dyslexia Screening and Assessment Strategies for Multilingual Learners

Problem: Once we notice persistent reading and spelling concerns in multilingual learners, the next challenge is knowing how to evaluate them without confusing language difference with disability.

Solution: We follow a structured, team-based assessment process that uses language-appropriate tools, examines skills in all relevant languages, and reads every score through the lens of language proficiency and cultural experience.

Step 1: Build a Shared Picture of Language and Schooling History

We begin with a careful record of the student's language and education background. This prevents us from misreading limited exposure as dyslexia manifestations across different languages.

• Map languages used at home, in the community, and at school, and note literacy experience in each.
• Clarify age of first exposure to each language and whether instruction has been consistent or interrupted.
• Gather information about prior evaluations, interventions, and response to targeted reading instruction.
• Include parent and caregiver observations about early language, memory for songs and routines, and learning letter names and sounds.

Step 2: Form a Collaborative Assessment Team

We avoid isolated decisions. Instead, we pull together a team that understands both literacy development and multilingual contexts.

• General and special educators contribute classroom data, work samples, and progress monitoring.
• Dyslexia specialists and school psychologists guide test selection and interpretation.
• Bilingual or dual-language teachers explain how typical learners progress in each program language.
• Families add cultural and linguistic context that formal tools often miss.

When possible, we involve professionals trained in bilingual dyslexia evaluation, or we seek expert consultation and professional development that deepens our shared understanding.

Step 3: Select Language-Appropriate, Evidence-Based Screeners

We choose tools that sample the critical reading components rather than general language ability. For multilingual learners, this means:

• Using reliable early screeners that measure phonological awareness, rapid naming, and basic decoding in the language of instruction.
• Adding parallel or comparable tasks in the home language when tools exist, or using structured informal tasks (word and pseudoword reading, spelling, sound manipulation).
• Avoiding overreliance on English-only assessments when the student's English exposure is limited or recent.
• Including oral language and vocabulary measures to distinguish language proficiency from decoding-based weaknesses.

Step 4: Examine Patterns Across Languages and Tasks

Once we have data, we look for consistent profiles rather than chasing single scores.

• Compare phonological awareness, word reading, and spelling across languages, noting whether weaknesses appear in one or multiple languages.
• Check for gaps between oral comprehension and single-word reading: a hallmark of common dyslexia symptoms in bilingual learners.
• Review work samples for persistent phonetic spelling, unstable sight word reading, and slow, labored text reading.
• Align assessment results with classroom performance and family reports, watching for the same difficulties across settings.

Step 5: Interpret Results Through a Multilingual Lens

We do not label every low score as dyslexia. Instead, we ask targeted questions:

• Is the student's language proficiency low in the language of the test but stronger in another language?
• Do decoding and spelling problems remain even where oral language is age-appropriate?
• Has the student received systematic, explicit instruction aligned with the Science of Reading, and did progress remain limited?
• Do difficulties persist over time, despite adapted teaching and additional exposure?

Underidentification of dyslexia in multilingual students often occurs when teams dismiss patterns as "just language." Balanced interpretation respects both the impact of limited exposure and the reality of neurobiological reading differences.

Step 6: Name the Needs and Plan Next Instructional Steps

After analysis, we articulate specific skill gaps rather than broad labels only. We identify whether the priority lies in phonological processing, decoding, spelling, or fluency, and whether each area is affected in one or more languages.

When teams feel uncertain, we seek guidance from specialists with deep training in bilingual assessment and structured literacy. Expert-led professional development, mentoring, and focused resources give us a shared framework, so screening and evaluation lead directly to effective instruction instead of more confusion for multilingual learners and their families. 

Overcoming Challenges and Misconceptions in Dyslexia Identification for Bilingual Students

Problem: Dyslexia in bilingual and ELL students often stays hidden behind assumptions about language learning, culture, and effort, so serious reading difficulties are postponed or mislabeled.

Solution: We name the most common misconceptions, watch their impact on students, and replace them with concrete advocacy steps grounded in multilingual assessment.

Common Misconceptions That Block Accurate Identification

Several beliefs keep teams from moving forward with assessment steps for dyslexia in ELLs:

• "It is just limited English." Persistent decoding and spelling problems in English are attributed only to second language status, even when similar issues appear in the home language.
• "They will catch up with more exposure." Years pass while everyone waits for English to "click," despite flat progress in phonological skills and word reading.
• "Strong speaking skills mean no disability." Fluent conversation masks foundational print weaknesses, so struggles with single-word reading are overlooked.
• "Cultural differences explain the gap." Low expectations or bias lead teams to blame family background instead of examining cross-language reading patterns.

Impact of Underdiagnosis on Student Outcomes

When dyslexia manifestations across different languages remain unrecognized, students receive fragmented support. They are placed in general ELL interventions that build vocabulary but leave decoding, spelling, and fluency needs untouched. Over time, gaps widen, confidence erodes, and students may withdraw from literacy tasks or accept a false story about their abilities.

Delayed identification also compresses the window for intensive, preventative intervention. By the time the profile is clear to everyone, the student has often accumulated years of frustration, inconsistent accommodations, and incomplete records of progress.

Strategies for Ongoing Monitoring and Advocacy

We counter these patterns with steady observation and informed requests for evaluation, rather than waiting for crisis points.

• Document patterns, not isolated events. Keep brief notes on decoding, spelling, and fluency across languages and settings, and notice what stays the same over time.
• Request data beyond global language scores. Ask for information on phonological awareness, word and pseudoword reading, and spelling, not only general English proficiency levels.
• Compare progress to targeted instruction. When students receive aligned, explicit teaching in phonics and phonological skills, track whether growth is steady, slow, or stalled.
• Use clear language in meetings. Name specific concerns: "difficulty learning letter - sound links in both languages" carries more weight than "struggling reader."
• Ask for bilingual-informed evaluation. Encourage teams to consult specialists with training in how to identify dyslexia in ELL students, or to seek professional learning that addresses multilingual assessment.

When we replace assumptions with precise observation and persistent questioning, bilingual students are less likely to be lost in the overlap between language learning and disability, and more likely to receive timely, appropriate support.

Identifying dyslexia in bilingual and English Language Learner students requires a nuanced understanding of both language development and neurobiological reading differences. Recognizing how dyslexia manifests across languages, distinguishing it from typical second language challenges, and following a comprehensive, culturally responsive assessment process are essential steps in ensuring accurate identification. Early signs must be closely monitored over time, and misconceptions that delay diagnosis must be actively challenged to prevent students from falling behind.
