Education
Students in Brandon are served by the Brandon Valley School District. As South Dakota allows parents to enroll their students at any school district, regardless of district boundaries, the school district also serves students from the surrounding areas. The Brandon Valley School District currently operates one high school, one middle school, one intermediate school, and four elementary schools. Brandon Valley High School, Brandon Valley Middle School, Brandon Valley Intermediate School, Brandon Elementary School and Robert Bennis Elementary School are all located within Brandon's city limits, while Valley Springs Elementary School is located a few miles east of Brandon in Valley Springs, and Fred Assam Elementary School is located a few miles west, in eastern Sioux Falls. In fall of 2015, the Brandon Valley School District added an intermediate school. The school is adjacent to Robert Bennis Elementary School and will educate fifth and sixth grade students. Because the city's population had been increasing exponentially, district officials were concerned that Brandon Valley Middle School, which serves grades 6–8, was reaching capacity. Voters living within the district voted to fund $5.95 million of the estimated $14 million required to build the school by way of property tax.
