Good Shepherd Cathedral School, formerly known as Good Shepherd Parish Academy or GSPA, began as a preschool in 1995. Founded by the erstwhile pastor of the Good Shepherd Parish, Msgr. Fidelis Ruben F. Limcaco, it was simply known then as Good Shepherd Parish Learning Center. The school was part of the many projects that Msgr. Fidelis had undertaken in his 27 years of pastoral service to the parishioners of Fairview. With the help of Dr. Carina G. Dacanay, the school's founding principal, the school has grown and developed complete services of preschool and grade school. In August 1, 2002, upon the retirement of Msgr. Fidelis, Msgr. Jesus Romulo C. Rañada, the former Rector of San Carlos Seminary, took over the directorship of the school. It was during his time that the school expanded further and established a high school and a Center for Integral Evangelization. It was also during Msgr. Rañada's term that the GSCS Main Building was built. In 2003, after the Good Shepherd Parish was elevated to the status of a cathedral of the newly established Diocese of Novaliches, the school was renamed as Good Shepherd Cathedral School. On May 13, 2007, the Most Rev. Antonio R. Tobias, D.D., Bishop Emeritus of Novaliches, appointed Rev. Fr. Albert N. Delvo as the school's new Director in concurrent capacity as superintendent of the diocesan schools of Novaliches. Fr. Delvo's coming signified the direction of Bishop Tobias towards unification of all the diocesan schools under one directorship. Fr. Delvo made possible the construction of a new four-story building named as the HEART Building to accommodate the steadily growing enrollment. In 2010, GSCS marked another milestone in its history when it celebrated its 15th founding anniversary. The year-long celebration culminated with the school's production of the musicalThe Dreamer which showcased the talents of GSCS students. The School Year 2012-2013 witnessed the school's initial implementation of the K to 12 Enhanced Basic Education Curriculum, in line with the national government's effort of improving the quality of basic education in the country. As part of the school's continuing mission of developing the potential of each student to its fullest, GSCS adopted the Dynamic Learning Program as a teaching method beginning School Year 2013-2014. In 2013, GSCS was given certification by the Private Education Assistance Committee - Fund for Assistance to Private Education. The certification serves as a quality assurance that the school complies with the minimum standards set by the Department of Education and qualifies it to the Educational Service Contracting Program of the government. In November 17–18, 2014, the Philippine Accrediting Association of Schools, Colleges and Universities conducted its preliminary visit to GSCS as part of the school's accreditation of its integrated basic education program. The following year, the school was given a "candidate status" by the PAASCU. In 2015, the school has been granted permit by the Department of Education to offer Senior High School beginning School Year 2016-2017. It was also during this year that the current vision-mission and core values of the school were introduced. In 2017, GSCS was formally given a Level I accreditation by the Philippine Accrediting Association of Schools, Colleges and Universities, the first basic education program in the Fairview area to be given such. Beginning School Year 2018-2019, GSCS has embraced the Whole Child Approach as a pedagogical paradigm. An initiative by the US-based Association for Supervision and Curriculum Development, the Whole Child Approach promotes a holistic and long-term development and success for students as guided by five important tenets - that is, every learner must be healthy, safe, engaged, supported and challenged.
