School Reviews
5 10/10/2025
As an alum who visits the facility periodically at class reunions (Class of 1969), it is my impression that the condition of the facility, the caliber of the faculty/staff/programs, and the accomplishments of the student body have significantly improved over the past 40+ years. The leadership of District 140 has long been been fiscally responsible, and parents have the good fortune to know that their children are given abundant, appropriate, and safe opportunities to learn and to grow. P.S. No one associated with Distric 140 paid or coerced or otherwise influenced me to offer these candid and heartfelt remarks.
