Pecatonica Community Unit School District #321 presently operates three school buildings. The Grade School, which was originally the high school, was built in three stages. The first stage was constructed in 1938 and was used as a high school for many years. The two additions to that structure were built in 1962 and 1970 respectively. The Middle School, also a former high school building, was built in 1958 and also accommodated two additions to the original structure in 1967 and 1970. In 2003, the current high school building opened. This state of the art facility has an approximate square footage of 107,000. Along with the new school, a football field and eight lane track were constructed during the building project. The high school complex also includes a baseball diamond and play field space for physical education classes. The theme for the current school reflects a flexible multi-purpose facility that will allow for both school based and community based activities. Within the facility, the building houses a modern library; a fine arts department, that includes graphic arts as well as chorus and band; an agricultural department; math, science, English departments, industrial technology, foreign language, and social sciences. The physical education department includes two gymnasiums, four locker rooms, a weight room, and training room. Additionally, Pecatonica High School offers two "off-campus" programs. Life-science classes are offered in a joint venture with the Illinois Department of Natural Resources at the Torstenson Youth Conservation Education Center located two miles East of town along the Pecatonica River. Students are also offered blacksmithing classes in a turn-of-the-century facility located near the middle school.
