When struggling with reading, educators often rely on broad interventions without clarity on where the breakdown occurs. This session equips educators with a diagnostic teaching approach that uses CBM Oral Reading Fluency (ORF) data to pinpoint instructional needs across Scarborough’s Reading Rope. Learn how percentile ranges reveal reading “symptoms” that can be traced to specific areas like decoding, vocabulary, or background knowledge. A step-by-step flowchart built from LETRS-aligned practices helps you link assessment to targeted instruction. The session also introduces a secondary diagnostic layer, like the Vanderbilt screener, as a tool to explore attention or regulation issues when standard interventions fall short. Leave with tools and strategies to move from generic supports to personalized solutions for struggling readers.
