The main results are as follows. Students in lower-income families were inadequate environment to take the online class from home. Indeed, they were in challenge to understand the contents of class and to work on the assignments. On the other hand, students in higher-income families received more supports from parents: participating with their children in online classes, supporting to school assignments and to private education. This shows that the educational gap to students based on household income is possible to link with the educational inequality. The efforts from school level was insufficient to reduce the current educational gaps.
