Abstract: Alcohol use among college students is a growing concern, contributing to academic, health, and social problems. This study evaluated the effectiveness of a structured teaching programme (STP) on improving knowledge regarding alcoholism among PUC students in Bangalore. A one-group pre-test post-test design was used. Findings showed that 60% of students initially had inadequate knowledge, which significantly improved after the STP, with a marked increase in mean post-test scores (t = 21.47, p < 0.001). Area of residence showed significant association with pre-test knowledge. The study concludes that STP is effective in enhancing students’ awareness about alcoholism in college life.
