In Malaysia, the cooperative sector is presumed to be the third sector that contributes to the nation’s economic growth, as highlighted in the National Co-operative Policy (2011-2020). Members of the cooperative are encouraged to get involved in the cooperative business and help their movement in which they are members. It is very difficult for researchers to study entrepreneurial intentions in many developing and developed countries by using the entrepreneurship model. The purpose of this research is to examine entrepreneurial intentions among cooperative members in Sarawak based on the Theory of Planned Behavior (TPB). The independent variables involved in this research were the Theory of Planned Behavior (TPB) and Entrepreneur Intentions, while the dependent variable was entrepreneurial performance. The basis for the variables was assessed by using a validated self-administered questionnaire. 200 respondents comprising cooperative members participated in the survey. Data obtained were than analysed using the Statistical Package for Social Science (SPSS) version 22. Entrepreneurial performance was found to have a moderate correlation with both measurements and was based on Guttmann’s rules. This study has provided empirical evidence about the relationship between each variable. Moreover, it revealed the factor that had the greatest influence on the entrepreneur’s performance among cooperative members, specifically in Sarawak. Areas for future research were also discussed in this research.
