Getting Started With the Grouping Matrix

When students are struggling to comprehend what they’re reading, the root cause needs to be identified and fixed. Thus, successful reading intervention often starts with accurate diagnosis and grouping. If you suspect your students have foundational skill weaknesses, like poor decoding skills, the Grouping Matrix is a practical place to start. It helps facilitate differentiated data-driven instruction and reporting.
