Teachers help students learn math, English, science, and other subjects though individual and classroom instruction. They prepare and teach lessons and administer grades to evaluate student performance. They evaluate performance by testing students' knowledge and abilities on exams and written assignments. More school districts and government agencies are asking teachers to look for other ways to evaluate student performance other than using standardized tests. Teachers must also discipline misbehaving students, consult with parents about their child's academic progress, and prepare report cards.
