The Nuestra Señora De Aranzazu Parochial School started as a preschool in 1968, the same year the puericulture center of San Mateo opened its nursery school.  Classes were held in a one-room makeshift building beside the parish hall.  Since it received an enthusiastic response from the Catholic parents, its enrollment increased at an unexpected rate.  The Catholic Women’s League Unit of the parish was first tasked to take charge of the management of the school as part of its apostolate.
