By 1935, the original schoolhouse was torn down and replaced with a new buff brick building that contained grades one through eleven. Two years later, a petition was presented to the Harris County School Board requesting that Tomball have its own school district. The petition was granted, which transferred all funds and debts to the Tomball Independent School District. The school on Cherry Street had grown so much that by 1938 a second campus was needed. Therefore, the district built a new red brick high school with a gymnasium and a swimming pool, which was located in the 700 block of Main Street.
