SLD Eligibility When Intervention Fidelity Is Weak

The most defensible position is that the team cannot yet make a defensible SLD determination. The data show low reading performance and below-average cognitive scores, but they do not meet the legal and professional threshold for ruling out exclusionary factors or documenting inadequate instruction.

Key gaps:

• Tier 3 fidelity (65%) is too low to conclude that Malik’s reading difficulty is not primarily due to inadequate instruction. The team should document the intervention used, attendance, dosage, and implementation accuracy, and either strengthen fidelity or extend the Tier 3 trial.
• English-language acquisition has not been adequately ruled out. Malik is a sequential bilingual with Spanish literacy. The team needs language-proficiency data in both languages, a bilingual assessment or interpreter-supported measures, and information about Spanish reading and oral language.
• A single IQ score should not drive the decision. The WISC-V FSIQ of 78 is low average, but the index scores and assessment conditions matter. The team should examine patterns of strengths and weaknesses across domains, not apply a rigid ability-achievement discrepancy formula.
• Dyslexia is a descriptive term, not an IDEA eligibility category. The parent should be told that the team will describe Malik’s reading profile and needs, and that a label alone does not determine services.

A defensible next step is to complete the comprehensive evaluation, including bilingual/language data, classroom observation, progress-monitoring trends, and intervention fidelity documentation. Eligibility should be decided only after the team can show that the reading problem is not primarily explained by language difference, inadequate instruction, or another disability.

I would respond to both without dismissing either concern.

To the parent:

• Acknowledge that the request comes from a real concern about reading and that the team will describe Malik’s reading profile precisely.
• Explain that “dyslexia” is a commonly used term for a pattern of word-reading and spelling difficulty, but IDEA eligibility uses categories such as specific learning disability. The team must first rule out language acquisition and instructional factors.
• Emphasize that services are based on need, not on a label. If Malik qualifies, the IEP will target decoding, fluency, and vocabulary, and progress will be monitored.
• Avoid promising a label before the evaluation is complete.

To the teacher:

• Reframe “try harder” as a hypothesis to test, not a conclusion. Ask what evidence supports motivation as the primary cause and what the teacher has observed during intervention.
• Point out that Malik has received 20 weeks of intervention and still has low fluency; effort alone is not an adequate explanation when fidelity has been inconsistent.
• Redirect the team to the data: attendance, engagement, language history, and intervention records.

This response keeps the meeting focused on data and avoids an adversarial tone while protecting the integrity of the evaluation.

I would collect data across languages and contexts, not rely on English-only measures.

• Language proficiency: English and Spanish oral language measures, including vocabulary, grammar, and listening comprehension, plus school records on English-learner services and progress.
• Bilingual reading data: Spanish letter-word identification, decoding, and reading comprehension, if the student has had Spanish literacy instruction; compare patterns across languages.
• Developmental and educational history: Age of English exposure, home literacy practices, preschool and early reading instruction, and any history of speech-language concerns.
• Classroom observation: Engagement, participation, response to instruction, and whether errors reflect English phonology or a broader word-reading deficit.
• Progress-monitoring data: Rate of growth under Tier 2 and Tier 3, with fidelity notes; compare Malik’s slope to similar English learners.
• Exclusionary-factor review: Attendance, vision/hearing, medical history, emotional/behavioral factors, and opportunity to learn.

The key reasoning is that English learners can show low English reading scores for reasons unrelated to disability. A converging pattern of difficulty in both languages, poor response to validated intervention, and intact oral comprehension would strengthen an SLD hypothesis; the opposite pattern would weigh against it.
