Welcome to Russell P. Schupmann Elementary! We proudly serve students in grades Pre-Kindergarten to 5. The 2015-16 school year was our first year to serve the students in Red Oak ISD. Named for long-time Red Oak ISD employee and supporter, Schupmann Elementary is set to begin a new chapter in our community. Our school is located in Glenn Heights and some of our marquee offerings include a renovated campus and Learning Commons area where students can collaborate while they learn.
