A public high school is an educational institution that provides secondary education to students, typically from grades 9 to 12. Funded by government sources, these schools are free for students to attend. Public high schools aim to prepare students for college, careers, and responsible citizenship through a diverse curriculum that includes subjects like math, science, literature, and social studies. In addition to academic courses, public high schools often offer extracurricular activities such as sports, music programs, and clubs. These activities help students develop social skills, teamwork, and leadership abilities, contributing to their overall personal growth and community involvement.
