This study is a quantitative study with descriptive and comparative analysis. The findings of this study indicate that governance and accountability are considered very important in Islamic Boarding Schools according to the perceptions of the principals, and from the perspective accountants regarding the practice of governance and accountability, this has begun to be implemented effectively even though it is still not consistently implemented by Islamic Boarding Schools, such as the lack of financial reports presented by Islamic Boarding Schools and incomplete by existing regulations.
