Fourth-Grade English Learner: Language Difference or Reading Disability?
A fourth-grade student, Lin, moved from China 18 months ago. She speaks Mandarin at home. Her English oral proficiency is intermediate: she can converse but has limited academic vocabulary. Her word reading accuracy is at grade level (50th percentile), but her reading comprehension is at the 10th percentile and her oral retell is sparse. Her teacher says she “doesn't understand what she reads” and suspects a learning disability. The school's English learner coordinator notes that Lin's oral language in Mandarin is strong. Lin's attendance is good, and she has had consistent English instruction. The reading specialist has reading assessment data in English only. The team meets in two weeks to decide on a special education referral. The specialist must propose an assessment and instructional plan that avoids misidentification.
1. What factors would you examine to distinguish a language acquisition issue from a reading disability for Lin, and what data are missing?

The central question is whether Lin's comprehension difficulty reflects normal English language acquisition or an underlying disability. I would examine:
- her oral language and literacy in Mandarin, including listening comprehension and narrative skill;
- her English listening comprehension, not just reading comprehension;
- academic vocabulary and background knowledge in English;
- her opportunity to learn, including ELD services and classroom supports;
- her error patterns in retell and comprehension questions;
- her response to targeted vocabulary and comprehension instruction;
- classroom observations and comparison with similar English learners.
The missing data are substantial: native-language assessment, English listening comprehension, prior schooling, and documented intervention response. Her grade-level word reading accuracy is important because it argues against a primary decoding disability. A sparse retell may reflect limited English expressive vocabulary rather than a comprehension disability. Before referral, the team should gather these data and provide a period of focused language and comprehension support. A disability determination based on English-only reading scores would risk misidentification.
2. Design a Tier 1/Tier 2 instructional response for Lin and explain how you would monitor progress.

The plan should integrate language development with comprehension instruction rather than wait for English to “catch up.” At Tier 1, I would recommend explicit academic vocabulary instruction with visuals, preteaching of key words, sentence frames, bilingual glossaries where available, and comprehension routines that activate background knowledge. Lin should have opportunities to discuss texts in small groups with scaffolds, and her ELD time should reinforce the same vocabulary and text structures used in class.
At Tier 2, I would provide small-group instruction two or three times weekly for 20–25 minutes, focusing on vocabulary depth, sentence comprehension, and retell using familiar and culturally relevant texts. I would model think-alouds and use graphic organizers. Progress monitoring should include curriculum-based vocabulary probes, a retell rubric scored for key ideas and language, and comprehension questions at both literal and inferential levels. I would compare her growth with that of similar English learners, not only with monolingual norms. After six to eight weeks, the team should review the slope. Improved retell and vocabulary would support a language-acquisition explanation; persistent difficulty despite good instruction and native-language support would justify further evaluation.
3. If the team still suspects a disability after intervention, what evidence should the evaluation include to support an accurate decision?
Read the worked answer
The evaluation must be comprehensive and nondiscriminatory. It should include assessment in both Mandarin and English where feasible, including oral language, phonological awareness, word reading, spelling, listening comprehension, and reading comprehension. The team should use qualified interpreters or bilingual evaluators and interpret scores cautiously when norms do not represent Lin's language history. The evaluation should also document the intervention she received, her rate of progress, attendance, and classroom observations.
Critically, the team must address exclusionary factors: lack of appropriate instruction in reading, limited English proficiency, and cultural or economic differences. A pattern of strengths in native-language skills and weak response to well-implemented intervention would strengthen a disability hypothesis; a pattern of comparable difficulty in both languages or steady growth with support would argue for continued language-focused intervention. Parent input and developmental history are essential. The decision should not rest on an English-only discrepancy score. The evaluation report should connect assessment results to instructional recommendations, not just assign a label.
