“…The previous literature on the assessment of internal control in the public sector is limited to two components out of the five components of internal control systems of the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Hence, the focus has been on control environment and control activities with little consideration given to the other three components that are equally important particularly for the financial operations of public sector institutions (Adebayo & Ilesanmi, 2020;Ademola et al, 2015;Akinkoye & Adewumi, 2019;Asaolu, Adedokun, & Monday, 2016;Aziz, Rahman, Alam, & Said, 2015;Izedonmi & Olateru-Olagbegi, 2018;Malowa, 2021;Muhunyo & Jagongo, 2018;Oladejo & Nwachukwu, 2021;Sharma & Senan, 2019;Udeh & Nwadialor, 2016;Yao, Yusheng, & Bah, 2017). The study fills this gap by taking into consideration the five components of internal control system mechanisms in the COSO framework in the assessment of the existence and implementation of internal control systems in the public sector contributing to the empirical literature.…”
