An American high school typically serves students in grades 9 through 12, usually ages 14 to 18. It offers a variety of subjects, including math, science, English, and social studies, along with elective courses like art and music. High schools often have extracurricular activities, such as sports teams and clubs, which help students develop social skills and interests outside of academics. Students are usually required to earn a certain number of credits to graduate, which involves passing courses and sometimes completing community service. High schools may also prepare students for post-secondary education, vocational training, or entering the workforce after graduation.
