The purposes of this inquiry were to seek the multicultural awareness of students at homogeneously and heterogeneously populated schools in the Municipality of Sungai Penuh, Jambi, Indonesia. Data were collected through administrating the adapted version of Multicultural Awareness Scale to 334 students from one homogeneously populated senior high school and one heterogeneously populated madrasah aliyah (Islamic senior high school). Data were analyzed by using Rasch Analysis and tests of inferential statistics. The results of data analyses indicated that 1) the students had a relatively high multicultural awarness, 2)the examination on the map of item endorsabilty indicated that the students had high cultural awareness but low self-awareness, 3) the students at the heterogeneously populated madrasah aliyah had a higher multicultural awareness than their counterparts at the homogeneously populated senior high school, and 4) no statistically significant differences were found in the comparisons of the students’ awareness across the demographic variables across and within the same school. Policy implications and suggestions for future research are also discussed.
