In response to this need, some school districts began experimenting with establishing separate intermediate schools for students in grades 7 and 8. These schools were designed to provide a bridge between elementary and high school, with a focus on preparing students for the more challenging academic environment of high school. The first junior high school is generally considered to be the Francis W. Parker School in Chicago, Illinois, which opened its doors in 1896.
The concept of junior high schools quickly gained popularity across the United States, and by the early 20th century, they had become a standard feature of the American educational system. In many school districts, junior high schools serve students in grades 6, 7, and 8, while in others they include grades 7 and 8 only. Today, there are over 12,000 junior high schools in the United States, serving millions of students each year.
