Tyler LaRiviere/Sun-Times Community colleges across Illinois are cautiously optimistic they will be able to bring back students for in-person classes this fall. And while a few four-year schools in the Chicago area — including Loyola University Chicago, Columbia College and DePaul University — have announced that students will be required to be vaccinated before returning to campus, most community colleges do not plan to make vaccines mandatory. After more than a year of nearly all remote coursework, most community colleges said they plan to offer classes four different ways this fall: fully in-person; a hybrid format involving a combination of both in-person and online instruction; virtual classes that involve online synchronous meetings; and fully asynchronous, online classes.
