The International Young Catholic Students (IYCS), also known as the International Young Christian Students, is a Specialised Catholic Action Movement that was inspired by Joseph Cardijn (the founder of the Young Christian Workers). YCS is a student Movement for, among, and led by secondary and tertiary students, (while also present in some places at the primary level), accompanied by adult animators and chaplains, that is concerned with the issues facing students and seek to raise awareness and action among students on broader issues of social justice, in solidarity with the poor, the oppressed and the marginalized through her famous methodology of “review of life” otherwise known as SEE, JUDGE, and ACT.
