UNIJES, the Federation of Jesuit University Centres to what IQS belongs, brings together Jesuit centres of university education in Spain, and coordinates and enhances collaboration among them.

The essential purpose of UNIJES is to encourage the Society of Jesus' MISSION of "the service of faith, of what the promotion of justice is an absolute requirement", within the Society in Spain's global apostolic strategy in the intellect and, specifically, university field; in this form the Society' activity contributes efficiently to a committed dialogue of faith with the culture of our time.
