It was conducted in 2 phases. The development of the model was done in the first phase by 1) studying relevant concepts, theories and research papers; 2)drafting an internal quality assurance operation model and 3) receiving deliberation and comments of 5 experts on the draft model. The appropriateness evaluation of the developed model was carried out in the second phase. Data was collected by using a 5-level rating scale questionnaire with content validity index between 0.80-1.00, discrimination power between 0.36-0.89 and overall reliability value at 0.99.
