This document summarizes a research project examining the ExCEL reading instruction model used at George Kelly School. The model groups students into high, medium, and low levels. Test score analyses found some gains in proficiency but minimal gains for low-level students. Interviews suggest the model may not adequately address student diversity and lessons often lack multicultural themes, which higher-interest students respond well to. The conclusion recommends further examining assessments, multicultural lessons, and supplementing lessons to better engage students.
