In evaluating eligibility for a Specific Learning Disability, which approach aligns with best practice?

• A. Rely solely on standardized achievement tests
• B. Consider progress in response to high-quality prereferral interventions
• C. Require a large IQ-achievement discrepancy
• D. Ignore prereferral data in decision making

Answer: (B)

The main idea here is that determining eligibility for a Specific Learning Disability should be based on how a student responds to high-quality, prereferral interventions and the data collected from that response. This approach, often called RTI or a response-to-instruction framework, uses progress monitoring to show whether the student is making adequate growth with targeted supports. If progress remains limited despite instruction of proven effectiveness, that pattern supports a special education consideration for SLD. Why this is the best fit: It centers on actual learning performance in the instructional setting, not just a one-time test score. Standardized achievement tests provide a snapshot of achievement at a single point in time and can miss how a child learns, responds to intervention, or benefits from instruction tailored to their needs. They also risk being influenced by factors like test anxiety or language differences. By contrast, progress data from prereferral interventions show whether the student’s learning gap persists despite appropriately delivered instruction, which is central to identifying an SLD accurately. The IQ–achievement discrepancy approach is outdated for many students because a large gap between IQ and achievement is not consistently predictive of an SLD, and relying on it can delay intervention or services for students who need them. Many students with SLD perform within the average IQ range but still struggle with specific academic skills; requiring a big discrepancy can miss these cases or delay necessary supports. Finally, prereferral data are essential. They reflect the student’s instructional history and the effectiveness of interventions provided before formal evaluation, helping to determine whether the difficulties are due to lack of appropriate instruction or a true disorder. So, focusing on progress during high-quality prereferral interventions aligns with best practice for identifying SLD.
