This report is one of the APCEIU's EIU Best Practices Series, which aims to encourage educators, scholars, and activists to implement and share local initiatives on EIU. The Series No.10 introduces a study of nine schools in Sri Lanka, which has been conducted to analyze current practices of gender education and provide suggestions for improvement. Upon careful assessment of documentary surveys, interviews, self-reports, and historical data analysis, the result indicates that gender equality and democratic participation are substantially provided and prioritized in Sri Lankan schools, in lieu of EIU theme of social justice. As common challenges still exist, the research notes the need to further examine learning patterns of boys and girls, classroom-specific gender issues, and good practices that promote role of women in democratic participation.
