Truancy remains a significant problem in the education system of countries when schooling is made compulsory for at least eleven years. The purpose of this study is to determine the factors contributing to truancy and the mean differences among the constructs based on the students’ ethnicity. The sample consisted of 472 truants from three main ethnic groups in Malaysia who have been routinely absent from school for 10 days to more than 40 days per year. Data on students’ truancy were obtained from the school administration. Results demonstrated that students’ attitudes toward school, environment in school, school administration, teachers’ teaching, teacher’s personality, and environment outside school, peers and family are significant constructs for truancy. Significant mean differences were also found in constructs of environment in the school, school administration and environment outside the school based on ethnicity.
