Junior high, also known as middle school, typically serves students in grades 6 through 8. It acts as a transition between elementary school and high school, helping students adjust to more complex subjects and social dynamics. In junior high, students often study a variety of subjects, including math, science, language arts, and social studies. They may also have opportunities to participate in extracurricular activities like sports, music, and clubs, which help them develop new skills and friendships.
