Based on recorded history, the De La Salle Brothers' supervision began, albeit informally, as far back as 1954.

In fact, there were three attempts to set up an office for the De La Salle Supervised Schools prior to 1995.

The second attempt was in De La Salle University on Taft Avenue, Manila, then spearheaded by Br.

While the establishment of these offices was a by-product of the existence of schools being assisted in many different areas, the Brothers' attempts have continued through the years.

Andrew Gonzalez confirmed this fact in his working paper, "Towards a Management Model for the Supervised Schools", published in 1982.

There were later claims that the supervision was "informal" and that the school was intended for the children of the expatriate employees residing in the refinery.

Villamonte was named Barrio Obrero and was the center where workers from nearby haciendas converged and formed a community.

The ICFS was established in 1949, through the efforts of the Young Ladies Association of Charity (YLAC) through its founding president, Miss Lydia Lizares.

The area allotted for the school was a one-and-a-half-hectare piece of land donated by the then governor, Alfredo Montelibano.

As the number of schools under the supervision of the LASSSAI increased, workshop meetings were held in August 2003 at La Salle Green Hills, and on June 10, 2004, at the DLSU-Manila.

This structure is in line with the De La Salle Philippines' (DLSP) declaration of the Revitalized Communion in Mission which includes "a unified system of supervising schools to extend educational services beyond the boundaries of Lasallian institutions".

A consultation with the heads of De La Salle District Schools by the Education, Research and Services (ERS) office of DLSP found a consensus among school heads with regard to extending educational services.
