The objectives of this study were to develop a sustainable curriculum framework and evaluate sustainability orientation of graduate Engineering implemented curriculum at Shiraz University. The study benefitted from a multi-phase mixed methods design. In first phase, an integrative review showed a sustainable curriculum framework with 10 curriculum components. In this curriculum, rationale is to develop a model of sustainable behaviour and culture and its' objectives are development of successful, confident and responsible students.

In the second phase of the study, for evaluation of sustainability orientation of the implemented curriculum. the quantitative results showed, some components did not satisfy the criterion in graduate Engineering implemented curriculum at Shiraz University. Furthermore, the qualitative strand research results revealed a lack of attention to issues such as minimising the use of non-renewable resources, lack of time flexibility, and repetitive, and censored curriculum as some causes of defects in the curriculum.
