  • Radnor High School is participating in a district initiative to enhance communication with students and parents through Schoology, an online learning management system that allows users to safely and securely share academic content. All RHS teachers will begin to use the system with students this school year. To increase efficiency of classroom management, teachers will not be updating their webpages as frequently. Directions for parent access to Schoology will be made available during the second semester of the school year. Home Access Center (HAC) will continue to serve as the place for parents to view current grades.
