The purpose of this action research project was to determine what effects response to intervention (RTI) had on student failures in a math. The researcher examined a Supported Study Hall, which is a tier II intervention strategy used to target key skills to help perform better. The Supported Study Hall was teacher led and only for students in the study who failed the pretest. In total, twenty-four Algebra I students were involved in the study. The research was conducted to analyze the effectiveness the Supported Study Hall had on student growth throughout the six-week intervention period. The findings revealed that the Supported Study Hall did in fact play a huge role in student growth from the start of the unit to the end of the unit. The data collected supports the need for this practice in schools today. The outcomes from the study provide key insight and highlight the direct benefits that RTI has on student growth in math.
