This article is about exploring the relationship between internal human resources auditing and environmental control in the US public sector. The main purpose of this study was to examine the extent to which the determinants of internal audit staff have the potential to influence the predictive value of the public sector control environment. The tools of the work are presented by a quantitative correlation analysis to determine the interdependence of variables (aspects of recruitment, accountability) and resultant indicator (public sector environment). By systematizing literary sources and approaches to solving the problem, as well as using the COSO 2013 Internal Control Framework as a theoretical framework, the authors focus on the question of how much internal audit recruitment, and accountability experience can influence in the foreseeable future and each of the two major COSO components. The empirical analysis was presented in the research, which made it possible to substantiate the following conclusions: the results of two multiple linear regression models did not show statistically significant except for recruitment, nonparametric correlation of Kendall’s Tau-b correlation is allowed to identify significant interrelationships development. The findings of the study may be useful for implementing further transformational changes in the functioning of the global economy in the context of the growing role and importance of international audit and its positive impact on the public sector in the United States. Keywords: Internal Auditing, Personnel Factors, Control Environment, Management, Innovation.

The purpose of this quantitative, correlational research was to examine to what extent the personnel factors of internal auditing departments predict the control environment within the public sector. Using the 2013 COSO Internal Control-Integrated Framework as the theoretical framework, we addressed the extent to which the internal audit staffing size per engagement, professional development, and auditing experience of auditors predict the overall control environment and each of the five components of COSO. The results of six multiple linear regression models showed no statistically significant with the exception between professional development and Principle 4 - Recruitment. A nonparametric Kendall’s tau-b correlation analysis revealed a significant relationship between professional development and Principle 4 Recruitment, τb = 0.388, p = 0.030. The results of this study may contribute to the positive global economy change by bringing into focus the role of auditing and its positive impact on the worldwide public auditing policy.

Whether it is the private sector or public sector, it is important for auditors to have an adequate framework when evaluating internal control systems governance. One of the most widely used frameworks used by audit practitioners is the COSO Internal Control-Integrated Framework Governance. As auditors examine different global frameworks, one can quickly identify the importance the COSO Internal Control-Integrated Framework Governance has on evaluating internal control systems globally. As audit practitioners, it is essential to have a universal framework that can systematically assist in evaluating an internal control system. As auditors and management look toward the future, whether it is private or public sector auditing, they can-will see the fingerprints of the COSO Internal Control-Integrated Framework Governance in evaluating future internal control systems throughout the world. This article are helpful to both the pravite sector management and policymakers.
