This study determined that the addition of Structured Learning Assistance (SLA) attendance increased passage rates (from 66.5% to 82%) of first year students in English 101 courses. The model predicts first year students' performance in college writing, controlling for variables such as American College Test scores, and gender. A quasi-experimental design and a logistic regression model of analysis were used. The results indicate that attendance to SLA has a significant and positive impact on passing English 101. The authors discuss the importance of formal peer-tutoring and support and recommend increasing the number of SLA sessions for first-year college students.
