Purpose: An internship is an essential part of vocational-oriented degree programs because it enhances the employability of graduates and prepares them for career development. Thus, it is important to understand how students view internships and whether they are satisfied with their internship experience. This paper explores the effects of organizational and individual factors on internship satisfaction. Design/methodology/approach: Based on a literature review on internship, we propose a theoretical model in which organizational factors, including supervisor support and task clarity, and individual factors, including interns' perceived functional value and perceived social value, can lead to internship satisfaction while task clarity, perceived functional value and perceived social value can affect interns' self-initiative behavior. The proposed model was tested using responses from 161 Chinese students in Macao SAR. Findings: The results of structural equation modeling indicated that supervisor support and perceived social value had direct and significant impacts on internship satisfaction while task clarity and perceived functional value had direct and significant impacts on interns' self-initiative behavior. Additionally, supervisor support significantly influenced task clarity, perceived functional value and perceived social value. Originality/value: The paper identifies that supervisor support has a strong and significant impact on internship satisfaction. Additionally, the current study indicates that organizations should pay great attention to appoint the right work supervisors who are able to assign appropriate tasks to interns, provide clear guidance and facilitate social interaction between interns and other people.
