With the recent and rapid transition to online teaching and learning in higher education, this explanatory study investigated the key design considerations used by business educators designing assessments suitable for online delivery. From a comprehensive literature review, we identified five key design considerations for online assessments: they must: (1) assure academic integrity; (2) allow for provision of quality feedback; (3) support a positive learning experience for students; (4) assure the integrity of student information; and (5) ensure all students have an equal chance to complete the assessment successfully. An additional consideration (authenticity) was identified through a survey of educators and four focus group discussions. Our analysis confirmed that scale of delivery and resource limitations, along with institutional policies and accreditation requirements, are broader and interrelated contextual factors that influence practices and decisions about assessment design. Focus group participants also identified constraints and trade-offs they negotiated in designing, evaluating and implementing online assessments. Based on our findings we propose a framework to assist educators in best-practice decision-making about online assessment design and contribute to the discourse between educators, higher education providers and professional accreditation bodies regarding online assessment.
