This paper deals with the critical appraisal of the integration of family values in education from the collaborative opinions shared by five groups of key informants composed of 10 parents, 10 Basic Education teachers, 10 members of religious groups, five BS Psychology students with intact families, and five government unit officers of the Department of Social Welfare and Development (DSWD) selected through purposive sampling technique based on a set of inclusive criteria. Further, the study was inspired by the following existentialist philosophers--Husserl, Heidegger, and Sartre—and the Unification Theory of Education of Tanabe (2007). Descriptive research design was utilized, employing mixed methods approaches as it explores and explains the opinions of the key informants and their worthy contributions in the realization of the integration of values in education and the marked significance of values in shaping people‘s real life accomplishments. A checklist of unstructured and open ended questions was asked in no particular order of the five groups of key informants, and the responses or opinions shared were treated as specific cases. The opinions were analyzed and filtered through an objective critical appraisal. The findings were presented, as well as the emerging themes. The researchers presented the quantitative analysis and the qualitative textual descriptions of the critical appraisal through the conceptual and theoretical lens and related philosophies of education. The highlights of the paper revealed the following: teaching of values starts in every home; the parents of the children are their first teachers; education remains unaccomplished without values; integration of values in education is an indicator of a successful/well achieved life; and the last and was perceived as the most essential theme from the opinions gathered was ―God is the first teacher, who taught the very first value, which was discipline, to His creatures in the Garden of Eden.‖ For the eidetic insights, the five groups of key informants representing five distinct sectors of the Philippine society strongly advocate that God is at the center of every human achievement; integration of values in education is the key in achieving the fullest of man‘s potential and essence of his existence. Consequently, collaborative communion with God is the highest and the most powerful standard of human capacity for accomplishment and life‘s wholeness.
