The Mermaid Schools are schools that natural merpeople take in their respective pods. The school teaches the merpeople to use their powers properly. When the merpeople graduate, they are given a Moon Ring and are initiated in the pod. The teachers are merpeople with experience with the powers. Rita Santos was a brilliant student of the Mermaid School of the Mako Island pod. She helped Nixie, Lyla and Sirena to master their powers, and gave them Moon Rings.
