How much do teachers in tertiary education know about the sustainability characteristics of their incoming students and, if this knowledge were to be available, how could their educational approaches be influenced by this knowledge? In New Zealand, Otago Polytechnic has committed itself to the goal that every graduate may think and act as a sustainable practitioner, and staff are changing their approach to teaching to achieve this. This research sought to benchmark the environmental worldview attributes of an incoming cohort of Otago Polytechnic students to support academic staff who need to know more about the sustainability interests and characteristics of their students, so that they may provide appropriate educational programmes. The research was also designed as the first stage of longer-term research to evaluate the impact of these institutional changes on how students transform during the period of their tertiary education experience. The data and analysis presented here suggest that even before students start to study in the institution different groups have substantially different sustainability values-sets. The authors anticipate that the research instruments and approaches used in the present study will contribute to a substantial national exploration of the sustainability value-sets of tertiary students.
