Higher learning institutions (HLIs) employ academic quality assurance (AQA) approach to assess quality performance in the higher education system. It aims to assist in the process of obtaining accreditation and recognition for HLIs. Modelling the AQA process is significant for understanding the current process and subsequently developing an information system. Therefore, this paper describes steps in modelling the academic quality assurance (AQA) process through unified modelling language (UML) notation. Metamodelling approach is used to identify the domain concepts and relationships before transform into UML-based foundations. The findings propose AQA domain into three different UML diagram which are use case modelling, structural modelling and behavioural modelling. Use case diagrams show the interaction between users and the system. While class diagrams structure the AQA endeavour process into categorisation systematically. The communication diagrams show the behavioural structure of the system through messages that pass between the objects in the interaction. This work gives stakeholder’s insight into AQA endeavour through UML notation proposed; i.e.; understanding the AQA process, assist in decision making process and helps in designing new system related to the endeavour process.
