"The pursuit of equity has always been a focus in the implementation of higher education policies of most countries. Concerning policy tools, many countries have implemented tuition-free policies in universities in recent years. However, is the waiving of university tuition a panacea for addressing equity in higher education? Especially after higher education becomes more widespread, will economically disadvantaged students have more opportunities to pass through the narrow gates of the top institutions. These questions are of great interest. Therefore, this study attempts to elucidate the relationship between the tuition-free policies of universities and equity in higher education by considering debates on university tuition policies in the United States and Japan. To achieve this goal, we first present the recent changes in university tuition policies in the United States and Japan. Second, we analyze the controversies and challenges caused by these tuition waiver policies, and once again examine the tuition structure and equity at public and private universities in Taiwan. Finally, we propose the following two countermeasures for reference in response to current issues regarding educational equity in in Taiwan."
