July 1947 – With 80 students, the first Don Bosco school in the Philippines, St. John Bosco Academy, started operations.

The old Oriente Hotel on F. Tanedo St., Tarlac, Tarlac was leased, and Fr. James J. Wilson, a US Army chaplain, was in charge of the Academy, becoming its first rector. The first day of classes was on July 6, 1947, and in the first year of its operation, the first batch of communicants was trained. The school also had its own mimeographed campus organ, “The Bosconian.” October 1948 — The campus was moved to Sto. Cristo, Tarlac, Tarlac. The school’s land area has become bigger at 17, 784 square meters. There were four Quonset huts that housed classes, a chapel, library, offices, and Fr. Wilson’s quarters. Later, a five-classroom building was erected. This was blessed by the then Apostolic Nuncio Msgr. Vagnoizzi.

January 11, 1949 — Another US Army Chaplain, Rev. Fr. William Mahoney, joined Fr. Wilson for about a year.

On January 31 of the same year, on the feast day of St. John Bosco, Fr. Wilson laid the foundation for a concrete gymnasium that for several years had been the best and the largest in Central Luzon. In April 1947, the first four students graduated from the Academy.They were Roberto Millena, Roberto Manlutac, Eusebio Dizon, and Alfredo Gomez. September 15, 1951 — Fr. Anthony Di Falco was installed as the first Salesian rector of the school. From then on, the school continued to receive more Salesians, and the focus on providing quality education was reinforced. During the same year, Salesian priests and brothers were expelled from the Congregation’s mission in China, and they found the Academy in the Philippines to be their new home. They were Fr. Vincent Ricaldone, Fr. Patrick Ryan, Fr. Rutkowski, Bro. Corcoran, and Bro. Mario Viel.

1973 — Fr. William Balocco succeeded Fr. George. At that time, Don Bosco Academy has already become known for leading quality education for boys in the province. The student population had also increased. Under the stewardship of Fr. Balocco, with the support of students and lay teachers, notably, Mr. Melencio Paras (Batch ’63), and assistance from benefactors, a fundraising was carried out which gave fruition to what is now the Don Bosco Gym and the Chapel.

The yearly project aims to help the school in sustaining quality education, provide more scholarships, and meet the requirements of the government’s K12 Education. Delegations from other Don Bosco schools in the Philippines, including newly re-opened Don Bosco Bacolor, Pampanga, also participated. Fr.

Pinatubo eruption, “would have the synergy and generosity happening in Don Bosco Tarlac.”

May 24, 2017 – The school, also celebrating the Feast of Mary Help of Christians, held the blessing of the new SHS building at the right wing of the campus.

Jay said: “This is our simple contribution to the education of the young people of the Province of Tarlac.” Architect Melvin Garcia (Batch ’88) collaborated with Escalona in the building’s design.
