Heterosexism is defined as a setting-level process that systematically privileges heterosexuality relative to homosexuality, based on the assumption that heterosexuality, as well as heterosexual power and privilege are the norm and the ideal. The many ways heterosexism is manifest in the physical - architectural, program - policy, suprapersonal, and social features of high schools are described followed by a proposal for a comprehensive assessment strategy. Strategies used in previous research are reviewed in terms of what is assessed, how it is assessed, and how it is analyzed. The author advocates for more comprehensive assessments and for school-level analyses to enable comparisons between schools, facilitate research on the effects of heterosexism, and provide a basis for evaluating interventions. Additional issues include reliability and validity, links between heterosexism and other forms of oppression, heterosexism in other contexts or at other levels, and implications for theory and practice in community psychology.
