This paper proposes four principles for managers and higher education educators who are designing units and programmes so as to be dual mode ready. `Dual mode' design and delivery enables students to equitably complete their studies fully online, while also offering on-campus experiences where possible. The four principles are: (1) All learning outcomes can be met irrespective of participation mode; (2) Teaching-learning activities are equitable across participation modes; (3) All students have equivalent opportunity to demonstrate achievement of learning outcomes; and (4) 'Online ready' design. Being dual mode ready will likely remain important as on-campus delivery may not be possible for all students. Further, universities may need to pivot rapidly to fully online delivery for a range of reasons, including pandemic-related circumstances. The four principles provide guidance on how best to ensure equity and fairness for students and teachers in a dual mode context.
