The main interest of this study is the gender and development (GAD) institutionalization in extension and training services (ETS) program of Laguna State Polytechnic University System (LSPU). The specific objectives of this research are: to analyze the institutionalization of GAD in ETS by conducting policy, program, and structure evaluation in four LSPU campuses; to determine the level and stage of GAD institutionalization in ETS using the phenomenological approach and GMEF; and to determine good practices and challenges in GAD institutionalization in ETS and identify the factors that have led to these practices and challenges. The data for evaluation was gathered through interviews, document reviews, and focus group discussions. This study found out that the GAD that is being institutionalized in ETS program in LSPU is very near to what ideal GAD should be. The programs lead towards empowering women and addressing inequalities and discrimination. The study pointed out many good practices and identified some challenges confronting the University ETS in GAD institutionalization. The good practices regarding GAD institutionalization in ETS program are mostly shown by the GAD Plan of the University. With its clear GAD policy and strong support from the University President and the Administrative Council, it was able to deliver several programs that promote the rights and welfare of women.
