Background: The improvement of nursing student competency currently is still an issue for the majority of nursing education institutions in Indonesia. This is due to their partnership with hospitals having not been supported by adequate policies and other factors. Objectives: The purpose of this study is to identify the appropriate model for improving student competency in a clinical study. The design used in this study was an observational study with cross-sectional approach. Methods: The research design used a cross-sectional approach involving five hospitals and five Universities. Three hundred and eighty-four participants were recruited from these sites. The data was analysed using multiple logistic regression. Results: The results showed that the partnership contributed 3.36 times, the patient variations 2.96 times, the job description of the clinical educator 2.30 times, a role model 2.28 times, and the expertise of the faculty educator 2.08 times towards the achievement of student competency in the clinical study. Conclusions: It can be concluded that the partnership aspect, patient variation, job description of the clinical educator, role model, the expertise of the faculty educator, and the level of education has a significant role to improve the achievements coming from the level of student competency in the clinical study. The results of this study can be used by nursing educational institutions, hospitals and the government to organise a nursing education model for the more optimal achievement of the student's competencies
