It is located at the university's Loyola Heights campus in Katipunan, Quezon City. It confers the Bachelor of Arts, Bachelor of Science, Bachelor of Fine Arts, Master of Arts, Master of Science, and Doctor of Philosophy degrees. It is composed of four schools, the School of Humanities, the John Gokongwei School of Management, the School of Science and Engineering, and the School of Social Sciences. The arrangement of the Loyola Schools academic buildings reflects its origin as a single College of Arts and Sciences. The Ateneo de Manila Grade School is the elementary education unit of the Ateneo de Manila, and is the oldest unit in existence - Ateneo began as a government-run primary school during the Spanish colonial period. It is an all-boys school with a population of around 4,000 students. The school had implemented the K-12 program since the 2013–14 academic year. The Ateneo de Manila Grade School is one of the first elementary schools in the Philippines to adopt the Singapore math curriculum. The Ateneo de Manila Junior High School (AJHS) is the middle school unit of the Ateneo de Manila University, offering the seventh to tenth grades for male students. It was established in 2013 to comply with the Philippines' K-12 education system. It currently occupies the old Ateneo High School campus. The AJHS has utilized a house system since 2016, labeled as "support systems for formation" aimed at "intensifying the care and formation the school bestows upon its students." The AJHS is divided according to the following four clusters, named after pivotal places in the life of Saint Ignatius of Loyola: Cardoner, La Storta, Montserrat, and Pamplona. Each cluster has dedicated class moderators, subject teachers, guidance counselors, immersion coordinators, and staff to cater to the specific needs of the students. The cluster is led by a "cluster coordinator" who organizes a variety of activities, such as mentorships and team building. Despite it offering secondary education, the AJHS offers an honors program for its English, Filipino, mathematics, and science classes. Students who choose to pursue the honors program are placed in a separate class with a more advanced program. The AJHS student body is governed by the "Sanggunian ng mga Mag-aaral ng Nakababatang Mataas na Paaralang Ateneo de Manila" (Sanggu-JHS; ).
