OSU defines a hybrid course as one that "includes both regularly scheduled on-site classroom meetings and significant online out-of-classroom components that replace regularly scheduled class meeting time."

In practice, face-to­ face meeting time in on-campus hybrid courses is generally reduced by 30 to 70% compared to traditional on-campus lecture courses. The most typical scheduling approach for these courses is one class meeting per week, though this varies especially when a course has a lab or recitation.

The broader term "blended learning" may be applied to various teaching modalities that integrate scheduled synchronous class sessions with substantial asynchronous learning activities. During the COVID-19 contingency, OSU defines blended learning specifically as "both on-campus and remote elements. Students attend class in-person and remotely. Some components may include synchronous remote learning."

All OSU academic colleges have hybrid courses; 900 courses officially carry the hybrid schedule type. The number of courses that carry this designation grew 27.2% between June 2020 and July 2021. Hybrid courses range from 350-student intro-level courses to graduate courses.

In the Schedule of Classes, the schedule type of hybrid courses is Hybrid (HYB). The face-to-face meeting hours of the course are listed in the schedule. The class notes briefly describe the hybrid nature of the course, for instance by saying, “In addition to classroom meetings, this hybrid section includes significant online components that reduce classroom meeting time.”

Hybrid courses offered on the Corvallis and OSU-Cascades campuses are considered on-campus courses, rather than Ecampus courses. Tuition for these hybrid courses is the same as for other on-campus courses. Ecampus offers hybrid degree programs and certificates at other sites such as the new OSU Portland Center.

All OSU faculty members are eligible to teach hybrid courses with the approval of their academic units.

A call for proposals is issued 3 times each year for participation in a 10-week Blended Learning Faculty Learning Community. Instructors selected for participation receive professional development funding and consultative support to take part in a learning community offered in a hybrid format and to redesign a traditional on-campus course offered in Corvallis as a blended course.
