In the school year 1956-1957 "The Spectrum" was established in an exclusive school for boys. That time, the then La Salle College was populated by less than 1,000 from preparatory kindergarten to undergraduate level. "The Spectrum" came out once every quarter in tabloid form, printed on white paper which was the standard during that time. Although the high school and college shared the same flag for their publications, they had separate issues prepared by their 30-member staff. Oscar L. Hilado (college) and Mario Guariňo (high school) were the first editors-in-chief of" The Spectrum". When La Salle opened its doors to female students in 1966, Lourdes Carisma Barredo became the first female editor-in-chief of the publication three years later.
