Chile has followed the international trend of implementing a standards-based reform, with the particularity of encompassing both academic and non-academic outcomes. Drawing on interview data from four school cases in Santiago, Chile, this study examines the role of attitudes in reform enactment, analyzing whether and how school actors' attitudes toward academic and non-academic performance indicators influence practice change. Alignment between attitudes toward academic standards and practice change is often disrupted by subjective norms, whereas attitudes toward non-academic indicators consistently drive behavior. This research sheds light on the complex interplay between attitudes and policy enactment, offering valuable insights.
