Riverdale Baptist School was founded in 1971 as a ministry of Riverdale Baptist Church. In its first year there was an enrollment of 188 students in kindergarten through the sixth grade. RBS rapidly grew into its current enrollment of over 800 students in grades K3 through 12th.

Never resting on its laurels, RBS has pushed to be a leader in academics, sports and technology. As an early adopter of growing technology, RBS has an ActivBoard in each classroom along with elementary and high school computer labs. In 2014, RBS took a leap forward in technology and became an Apple school, offering iPads to each student in grades 3 through 12 (as well as to all teaching staff).
