It is a private sectarian school situated at the back of the Cathedral Shrine and Parish of the Good Shepherd, the seat of the Bishop of Novaliches.

Fidelis Ruben F. Limcaco, it was simply known then as Good Shepherd Parish Learning Center.

Jesus Romulo C. Rañada, the former Rector of San Carlos Seminary, took over the directorship of the school.

Delvo's coming signified the direction of Bishop Tobias towards unification of all the diocesan schools under one directorship.

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.

Beginning School Year 2018–2019, GSCS has adopted the Whole Child Approach as a pedagogical paradigm.

An initiative by the US-based Association for Supervision and Curriculum Development (ASCD), the Whole Child Approach promotes a holistic and long-term development and success for students as guided by five (5) important tenets - that is, every learner must be healthy, safe, engaged, supported and challenged.
