This paper describes current research to drive future research challenges in accounting quality. The definition of accounting quality is mainly varying depending on the objective that the study pointed. Previous research revealed that many proxies describe the accounting quality but most of them from the financial perspective. Furthermore, this paper tries to expose this research issue in the behavioural approach and drive future research in the mixed method. It concludes that the behavioural issues can be a research model, triggering future research challenges in accounting quality. The authors support these triggers from the perspectives of political hegemony, bureaucracy ratcheting, cognitive distortion, and international accounting standard. Finally, we infer and simultaneously predict that accounting quality would broaden its concepts and lasting impression in the 21st century.
