Caodaist institutions understand spiritual life and social responsibility as deeply intertwined, so their communities devote considerable energy to both education and charitable service. In the educational sphere, they operate or sponsor primary and secondary schools, particularly in Vietnam, where standard curricula are combined with moral and religious instruction rooted in Caodaist teachings. Beyond formal schooling, they organize religious education classes that introduce doctrine, ethics, and basic literacy to children and adults connected with the temples. Scholarships, tuition assistance, and the provision of school supplies are extended to students of limited means, reflecting a concern that material hardship should not block access to learning. In many places, lectures, study circles, and cultural programs on literature, music, history, and interfaith understanding are hosted to foster moral uplift and social harmony.

Charitable activities are similarly broad and are regarded as a concrete expression of compassion and universal love. Caodaist organizations support clinics, dispensaries, and sometimes hospitals that provide low-cost or free medical care to the wider community. They fund or operate orphanages and homes for the elderly or disabled, and they distribute food, clothing, and other basic necessities to the poor, to orphans, and to those affected by war or disaster. Their communities also mobilize volunteers and donations in times of natural calamity, offering disaster relief and emergency assistance in coordination with local structures where possible. In all of this, the services are generally extended to anyone in need, not restricted to adherents, embodying an ethic in which spiritual merit is cultivated through concrete acts of service to all beings.
