This report presents the main findings from New Zealand Council for Educational Research's (NZCER's) latest survey of secondary schools, conducted in July and August 2015. These surveys have been done every 3 years since 2003. They provide a comprehensive national picture of what is happening in New Zealand secondary schools, how things have changed over time and the impact of policy changes. In this report, the authors discuss statistically significant differences in responses related to school decile, location and size. Included are the perspectives of principals, teachers, parents and board of trustee members on a wide range of issues. Sample characteristics are appended.
