Walnut Grove opened as a UIL Class 5A school. As it opened in between realignment periods, the school played the 2023 football season without a district, having to play multiple private schools and out of state teams in order to create a schedule. This included Malvern High School in Arkansas and the Cathedral Fighting Irish from El Paso at a neutral site.
