The purpose of this explanatory mixed methods study was to examine faculty perceptions of effectiveness and impact of professional development for teaching, research, and service in a higher education institution in South Texas. This study provided quantitative and qualitative data from 165 faculty members from a Hispanic Serving Institution in South Texas. Participants in this research consisted of tenured 56.9% (n = 95) and tenure-track 41.1% (n = 69) faculty members who taught in different departments in the colleges of Health Affairs, Sciences, Liberal Arts, Engineering and Computer Sciences, Business and Entrepreneurship, and Education and P-16 Integration. The quantitative data provided evidence to suggest that there is a relationship between professional development and perceived levels of support and community; although, not for productivity in teaching and research. Themes for professional development for teaching, research, and service included motivation to learn, self-directed learning, and resources for service.
