Colegio San Ignacio de Loyola is a Catholic Jesuit college-preparatory school founded by the Society of Jesus in San Juan, Puerto Rico in 1952. Colegio San Ignacio is an academic institution on the island that has educated some influential and outstanding leaders of Puerto Rico, such as Ruben Berrios and Raúl Juliá. It is considered a college prep school, since 100% of graduates go on to pursue college degrees and around 50% of them study outside of the island, mainly in the continental United States. Many of them attend top-ranked colleges and universities.
