The first school in Puerto Rico and the first school in the United States after Puerto Rico became a US territory, was the Escuela de Gramatica (Grammer School). The school was established by Bishop Alonso Manso in 1513, in the area where the Cathedral of San Juan was to be constructed. The school was free of charge and the courses taught were Latin language, literature, history, science, art, philosophy and theology.
Education in Puerto Rico is divided in three levels—Primary (elementary school grades 1–6), Secondary (intermediate and high school grades 7–12), and Higher Level (undergraduate and graduate studies). As of 2002, the literacy rate of the Puerto Rican population was 94.1%; by gender, it was 93.9% for males and 94.4% for females. According to the 2000 Census, 60.0% of the population attained a high school degree or higher level of education, and 18.3% has a bachelor's degree or higher.
Instruction at the primary school level is compulsory between the ages of 5 and 18 and is enforced by the state. The Constitution of Puerto Rico grants the right to an education to every citizen on the island. To this end, public schools in Puerto Rico provide free and non-sectarian education at the elementary and secondary levels. At any of the three levels, students may attend either public or private schools. As of 1999, there were 1532 public schools and 569 private schools in the island.
The largest and oldest university system in Puerto Rico is the public University of Puerto Rico (UPR) with 11 campuses.

Mendez which operates the Universidad del Turabo, Metropolitan University and Universidad del Este, the multi-campus Inter American University, the Pontifical Catholic University, and the Universidad del Sagrado Corazón.
