Learn about efficient integration solutions for small, medium, and large schools and districts: MyClassroom and OneRoster. Santillana's new MyClassroom makes it simple to set up small and medium-sized schools. Schools create their courses based on the class periods and add students with just a few clicks. And we are now OneRoster compliant! OneRoster allows us to integrate our platform with any SIS or other rostering system, providing fully automatic set-up for larger schools and districts with specific integration requirements.
