This study aimed to identify the perceptions of differentiated mathematics instruction among educators in an inner-city tutoring program. The researcher conducted this study in a private tutoring program that works with a Title 1, struggling school in a large metropolitan city. Qualitative research methods were applied to identify perceptions among educators considering their role, students' perceived perceptions, differentiation methods, strengths, and weaknesses. The study emphasized many academic and social-emotional advantages to differentiated instruction while addressing the major challenge of additional educator workload.
