The current study examined how schoolwide norms came together into distinct profiles and how norm profile membership was linked to adolescent well-being. Using school-level (N = 786) and student-level data (N = 174,587 12th grade students; 52% female; 64% White, 13% Latino, 12% Black, 12% other) from Monitoring the Future (MTF), we identified four distinct school profiles-average, academic, prepped-for-college, party-that had unique patterns of shared norms. Compared with average schools, academic schools (high academics and low substance use and social integration norms) were most advantageous for students, prepped-for-college schools (high academics, substance use, and social integration norms) had both benefits and drawbacks, and party schools (low academics and high substance use and social integration norms) were most detrimental.
