The purpose of the present study is to investigate the grade level and gender differences in a school-based reading tutoring program. The treatment group included 10 first-grade and 12 second-grade struggling readers, and the control group included 41 first-grade and 63 second-grade nonstruggling readers. The tutors were teacher candidates in an elementary education program at a Midwest university. Each student in the treatment group was given four 30-minute tutoring sessions every week for one semester. Results showed that first-grade struggling readers had a significantly higher reading gain than second-grade struggling readers. In addition, first-grade male struggling readers had significantly higher exit Developmental Reading Assessment (DRA) scores than their entry DRA scores, but first-grade female struggling readers did not have significantly higher exit DRA scores than their entry DRA scores.
