Also known as hybrid flexible, the term refers to an instructional mode for a hybrid college course that permits flexible learner attendance. Learners may attend along a spectrum of options, from fully online through full in-person (face-to-face / F2F). There are commonly four pillars of HyFlex:

• Learner Choice: Learners (not the instructor) determine when and how they will participate within guidelines. Participation options often change by topic, week, module, lesson, etc.
• Equivalency: Learning activities regardless of delivery mode support the same learning outcome(s).
• Reusability: Use of the same learning objects for all students in all participation modes.
• Accessibility: Learners need the technology and skills to use the technology to access course materials. The instructor ensures learners have access to the required technology, skills training, and support to be successful.

Some institutions include a pillar for equity; that learners in all modalities have equal opportunities to engage in course activities, receive feedback, and ask questions.
