High school teachers take attendance, keep track of textbooks and other supplies, and establish classroom rules so students can work and learn.

High school teachers develop lesson plans to teach subjects according to the school or district curriculum. They assign and grade homework. They give tests to check students' progress. They record test scores. They analyze the scores to create progress reports and final grades.

High school teachers may supervise student activities after school or during lunch breaks. High school teachers may also supervise school dances, sports events, or other school activities.

High school teachers participate in faculty meetings. They discuss school and class issues with school administrators. They may also participate in local or national conferences where teachers share ideas and teaching methods.
