<em>The level of customer satisfaction in the world of education has long been a necessity. The difference between private and public schools is no longer significant. Competition and competitive nature of private and public schools require new changes and conceptions where management of educational institutions is concerned. The implementation of a full-day-school system in Indonesia cannot be separated from the phenomena related to ‘superior schools’ back in the 1990s—many of which were pioneered by private schools, especially those that were motivated by implementing Islamic values. Such schools are usually referred to as schools that focus primarily on the quality of the teaching and learning processes rather than on the quality of students input.
