The quality of the programmes and courses in ODL depends on the academics that plan the programmes, develop the curriculum, manage courses and programmes and carry out administrative duties. It is observed that the academics often complain of work overload. It also appears there is a mix-up in integrating the mode of planning workload in the conventional universities into the open and distance education universities. This may be attributed to inadequate spread in the duties assigned, which if not checked could affect the quality of teaching and learning. This necessitated the study that was carried out to determine academic workload in NOUN. The findings revealed a gap between academic activities and adequate utilisation of time. Also, inadequate spread of activities affects the quality of the academic inputs. This led to the development of academic workload model to guide the spread of academic activities in open and distance learning.
