Purpose: Several studies have attempted to explain the integration of sustainable development in business school curricula. However, little is known about who (male students vs female students), at which age (under 21, 21-25 and 26-30) and at which stage of their undergraduate education (freshman, junior or senior) can attain and retain an adequate understanding of sustainability in accounting education. For this reason, the present study aims to investigate the students' interest in sustainability in accounting with respect to their demographic factors. Design/methodology/approach: The study used a quantitative research design where data were collected at a single point in time. Further, an independent sample t-test, one-way ANOVA and factorial design were performed on 132 responses conveniently collected from accounting students in the College of Business Administration (COBA) at Prince Mohammad Bin Fahd University (PMU) in Al Khobar, Saudi Arabia. Findings: The study found no differences between the attitudes of male and female students toward sustainability in accounting education. Similarly, no statistical differences were found in the three age categories identified in this study. However, significant results were found throughout the different academic classifications (seniority): freshman students, junior students and senior students. Further, differences in the mean scores for freshman and junior accounting students were different between the male and female students, indicating that both male and female senior students' attitudes toward sustainability in accounting education were higher than those of male and female freshman and junior accounting students. The study concluded that students achieve an adequate understanding of sustainability in accounting education related to the relativism category of the Perry model of intellectual development. Originality/value: Literature on attitude of students toward sustainability in education, specifically accounting education, is questionable and needs further exploration. This is due to the fact that only a small number of accounting students have been exposed to sustainable accounting education. Similarly, a recent study found a significant deficiency in sustainable accounting education in four Saudi Arabian universities, with only 4.5% of respondents knowing the comprehensive definition of sustainable development and 88% respondents having very low to low familiarity with the term sustainability.
