This varies considerably by institution. Some schools have created a new registration code (HyFlex or another name) that reflects the local characteristics of the approach. Sometimes multiple class meeting patterns are used; 1) an assigned time in a room and 2) an indication that the course is available asynchronously. Sometimes class registration systems list two class sections – one online and one in the classroom – and allow students to register for either, then invite students to participate in either mode. The two sections are usually combined in the LMS to support the work of a single faculty teaching both sections.
