This study aimed to identify the determinants of entrepreneurial intention and assess the environmental factors affecting entrepreneurial intention among SHS students in San Jose, Occidental Mindoro. The researcher used a mixed sequential exploratory method and employed statistical treatment such as Thematic analysis, Frequency & Percent Distribution, Weighted Means, Structural Equation Modeling (SEM) and Beta Coefficient. The data were drawn from 293 respondents in grade 12 senior high school students of the selected three public schools in San Jose that have business subject/s in their curriculum. This study found out that feasibility and desirability are the parameters of environmental factors. The study also revealed that SHS students' entrepreneurial intentions were to a very high extent to the students' feasibility and desirability. Senior high school students' strong appreciation for the feasibility of pursuing entrepreneurial courses can be related to their realization that they have the essential skills and capability to become entrepreneurs. Furthermore, a person's willingness to pursue entrepreneurship is based on an assessment of the expectations and beliefs that he will get from it. Based on the findings, the study concludes that the students' ability to lead others is related to their understanding that they have necessary abilities and competence to become entrepreneurs. Therefore, this study recommends to the educational leaders of public schools that they continue to nourish their students' minds on what they want to be. Also, educational authorities may utilize the proposed action plan to effectively increase senior high school students' entrepreneurial intention in terms of feasibility and desirability.
