Grade 1 English Learner: Dyslexia Risk or Language Difference?
Diego is a first grader whose home language is Spanish; he has been in English-only instruction since kindergarten. His teacher refers him because he "isn't learning to read like the others." Data: English letter-sound knowledge 18/26; phoneme segmentation 5/10 in English; English word reading 4/20 on a decodable list; rapid automatized naming of colors and objects below the 10th percentile; English picture vocabulary standard score 86, with classroom observation noting he participates and tells stories well in Spanish. The bilingual aide reports he learned letter names easily in Spanish last year and is blending syllables in Spanish as expected. His older brother received reading intervention in second grade and "still hates reading." Attendance is 92%. The school's default practice is to wait until students have had three years of English before considering evaluation. The team meets in two weeks.
1. Should the team wait for more English proficiency before considering screening for dyslexia risk? Justify your reasoning with the data provided.

No - the wait-to-exit-English rule is not defensible here.
Waiting is reasonable when the concern is overall English proficiency: a child still acquiring vocabulary and syntax will look weak on English-only measures for reasons unrelated to reading disability. But that logic applies to language measures, not to the specific profile in front of the team.
The converging signs are the ones that cut across languages:
- Phoneme segmentation at 5/10 in English is a code-based skill, not a vocabulary skill.
- RAN below the 10th percentile is a well-established, largely language-independent predictor of later word-reading difficulty. It is one of the strongest single flags for dyslexia risk.
- Word reading at 4/20 with letter-sound knowledge at 18/26 - he knows many sounds but cannot apply them, which is the decoding gap, not a vocabulary gap.
- Family history of persistent reading difficulty in a sibling.
- His Spanish literacy is developing as expected - letter names came easily, syllable blending is on track. A child with a general language-learning problem would typically struggle in both languages, not just in English word reading.
So the profile is specific to English word reading despite adequate Spanish early literacy and engaged oral language. That specificity is exactly what distinguishes dyslexia risk from a language difference, and it warrants screening now, not in two years.
2. What additional data would you gather, and how would each piece separate dyslexia risk from English language acquisition and from developmental language disorder?
Read the worked answer
Gather:
- Spanish early literacy measures (letter sounds, syllable and phoneme tasks, word reading) administered by the bilingual aide. If Spanish decoding is also weak, the concern is broader; if Spanish decoding is developing, the difficulty is specific to English - pointing toward dyslexia risk rather than a general learning problem.
- Hearing and vision screening. Rule out the cheap explanations first.
- English and Spanish language samples, plus teacher report on first-language development. DLD is characterized by difficulty in the first language too - limited vocabulary, grammatical errors, word-finding problems - and would show up in Spanish conversation, not only in English reading.
- Listening comprehension versus reading comprehension in English, using simple pictured passages read aloud. Strong listening with weak reading points to a word-level problem; weak listening comprehension in both languages raises a language-disorder question.
- A dyslexia-specific screener covering phonological awareness, rapid naming, and word reading, plus classroom work samples and attendance patterns.
- A structured family history, not just the sibling anecdote.
How they separate: dyslexia risk is a specific word-reading and phonological deficit with relatively preserved oral language; language difference is a pattern of lower English scores that tracks English exposure; DLD shows up in the home language and in oral comprehension and production. The first two weeks of data collection should be enough to see which pattern fits.
3. If the team decides to intervene before a full evaluation, what should Tier 2 include and on what timeline should they reconvene?
Read the worked answer
Tier 2 content:
- Phonological awareness and phonics, 20 minutes daily, small group, using the same English code he is expected to read, with heavy modeling and cumulative review. His letter-sound knowledge is a strength - use it.
- Explicit linkage of sound to print (Elkonin boxes with letters, word building) because he knows 18 sounds but reads 4 of 20 words; the gap is application, not inventory.
- Rapid naming practice embedded as a short, game-like activity (repeated reading of familiar letter and object arrays) - it does not replace code instruction but addresses a flagged predictor.
- Vocabulary support in both languages so that English vocabulary growth is not mistaken for reading progress and so his Spanish does not stall.
Timeline: baseline this week, collect four to six weeks of intervention data, and reconvene at six weeks - not at the end of the year. At that meeting, review the trend line, fidelity, and the additional assessment results.
Decision rule: if word reading and segmentation are rising, continue and monitor. If the trend is flat after six weeks of well-implemented instruction with good attendance, move to a comprehensive evaluation rather than starting another cycle of the same intervention. Language-minority status is not a reason to delay that decision when the data point to a specific word-reading deficit.
