[1] Situated on a 15-acre (61,000 m2) campus adjacent to Rockford's Sinnissippi Park and overlooking the Rock River, Keith School, as it is commonly referred to, is located at 1 Jacoby Place, on the site of the former Shoudy Mansion and carriage house.

It is composed of the Head of School and past and present parents of Keith students, along with prominent civic figures.

Students may study a foreign language, add a lab-based science (sixth, seventh, eighth grade, or Biology, Chemistry, Physics, or Environmental Science), delve into an AP (Advanced Placement) course in English, U.S. History, Biology, Calculus AB or BC, Music Theory, Physics, European History, Chemistry, or Statistics.

Keith also hosts an annual spelling bee for fifth to eighth graders, the winner of which goes on to compete at the state level.

The school has found its most success in Girls' Volleyball, winning three consecutive state titles from 2013-2015 with a record of 111-12 over those three seasons.

The KPA meets once a month to discuss the Association's fundraising activities as well as extra-curricular events planned and coordinated by its officers and members.
