A Fifth Grader Who Reads Far Below Grade Level
Devon is 10 years old and in fifth grade. He was referred in October: oral reading fluency is 38 words correct per minute on a grade-level passage, against a grade-level benchmark of 120. Word reading accuracy is 55%, but listening comprehension is at the 60th percentile and math at the 70th. He reverses b and d, reads 'was' for 'saw,' and takes a long time to name letters and digits on a rapid-naming task. Phonological awareness is at the 20th percentile; vocabulary and syntax are average. Hearing and vision screening are normal, attendance is 94%, and English is the only language at home. His teacher reports that he is off-task during independent reading and says he 'just doesn't try.' The school uses a tiered model; Devon has had six weeks of Tier 2 small-group phonics, with progress-monitoring scores flat at about 40 words correct per minute. The team meets in two weeks and must decide whether to evaluate for special education.
1. Which hypotheses fit the data, and which are ruled out by which evidence?

The profile is specific to word-level reading: fluency of 38 words correct per minute against a 120 benchmark, poor word accuracy, letter reversals, slow rapid naming, and phonological awareness at the 20th percentile, while listening comprehension and math are average to above. That dissociation argues against a general cognitive or language delay and against a math or intellectual disability. The rapid-naming and phonological weaknesses plus strong listening comprehension fit dyslexia. Attention is not ruled out, but off-task behavior in reading is plausibly a consequence of frustration; attention alone would not produce the rapid-naming and phonological pattern. Lack of adequate instruction is partly addressed by six weeks of Tier 2, but six weeks is short, and the flat slope matters only if fidelity was adequate. Sensory issues are ruled out by screening; limited English exposure is ruled out because English is the only home language. The team should keep two live hypotheses, dyslexia and inadequate intervention, until fidelity is checked.
2. What additional data should the team gather before the meeting, and why does each matter?
Read the worked answer
Request implementation fidelity data for Tier 2: minutes delivered, group size, attendance, and whether the program was followed. Get a norm-referenced word-reading and phonological processing measure rather than relying on curriculum-based measures alone. Have someone observe Devon in reading and in math to see whether off-task behavior is context-specific. Collect a developmental and family history of reading difficulty, and check whether the Tier 2 slope is flat across all six weeks or only later. Also verify that the oral reading fluency passages are grade-level and that the benchmark is appropriate. These data distinguish a persistent word-level deficit from a delivery problem, and they prevent a high-stakes decision based on a single measure.
3. Recommend a decision and defend it against both over-identification and under-identification.
Read the worked answer
Recommend a full evaluation, but condition it on adequate Tier 2 fidelity. The dual discrepancy - low level and flat slope despite intervention - plus the specific cognitive profile supports evaluation now rather than another waiting period. Do not rely on an IQ-achievement discrepancy, which would delay service and misidentify many students; use the pattern of strengths and weaknesses plus response data. To guard against over-identification, rule out inadequate instruction explicitly and document fidelity. To guard against under-identification, do not attribute the problem to motivation, which the observation data may contradict. If fidelity was poor, fix Tier 2 first with a time limit and continue progress monitoring, but keep the referral open.
