Malaysia is a multicultural country constituting three major ethno-cultural groups, Malay and Bumiputera, Chinese and Indian. Owing to its diverse cultures attempts through a number of channels, politics, economics and social were made to bring about national integration. School is thought to be the most effective platform to bring about national integration based on the multicultural framework. This study examines the influence of both the selected school and student background variables on integration. The survey conducted on Form Four and Form Five students found that integration is not monolithic but tends to be interpreted into three frameworks or models: assimilation, multiple-identities and multiculturalism. Ethno-religious-cultural backgrounds seem to be much more influential than the school variables in determining not only the strength but also student preference for a specific integration framework or model.
