This study attempts to identify the factors affecting parents' decision to send their children to independent high schools with special reference to the relative influence of social class. For this study, 635 parents of high school-bound students were surveyed, and the results were analyzed by using cross tabulations and logistic regressions. The results show that social class is closely related to the demand for the enrollment in independent high schools. In particular, a father's occupation makes the most notable difference in the probability of attendance. Household income itself does not exert a direct impact on the probability of attendance, however. The effect of household income on the probability of attendance is proven to be mediated by a father's occupation. As could be reasonably expected, those parents who are discontent with the current education system and/or have a higher level of educational expectations for their children are more likely to send their children to independent high schools. The empirical findings provide insights into the school choice structure ensuing the introduction of independent high schools. By and large, the choice to attend independent high schools seems to be made by those from the upper end of social classes. Although the introduction of independent high schools may promote school effectiveness, it is likely to exacerbate socioeconomic segregation between schools.
