The Antipolo Immaculate Conception School owes it’s beginning to the kindergarten founded by the late Ms. Agapita Sumulong Panganiban, better known as ” LOLA PETANG”.

In 1956, after the liberation, on the ground floor of a two-storey house on Lopez Jaena St, Lola Petang opened her kindergarten teaching therein orphans and children of poor families. Hers was the first and only kindergarten then in Antipolo.

Her first 40 students grew in number and burgeoned into hundreds as years went by. Eventually, Lola Pet relinquished the management of the school to her niece, Mrs. Lolita Mendoza, who sought and was granted the official permit to permit the operation of the school in 1982.

Thus, the Antipolo Kindergarten which Lola Pet founded was renamed Immaculate Conception Kindergarten (ICK) in honor of Antipolo’s patron saint as well as the patron saint of our country.

Before opening the Academic Year 1989 – 1990, due to the rapid increase in enrollment, the school president constructed a four – room building. Government recognition was granted in 1991 for Nursery, Kindergarten and Preparatory or the Pre – School Level.

After 3 years, for the School Year 1993 – 1994, classes from Grade I to Grade VI commenced. The name of the school was sectarian institution. Government Recognition for the Elementary Level was granted after a year.

In deference to the parents’ clamor for the secondary education of their children, the AICS High School Department opened on June 8, 1996.

Over the years, AICS has produced Immaculadians who had been proclaimed champions in various academic competitions particularly in Mathematics.

In sports, AICS has consistently produced winners in District and City Meet as well as in Southern tagalong Calabarzon Athletic Meet and Palarong pambansa.

The AICS Drum & Lyre Corps had been bestowed the Hall of Fame for both high school and elementary categories.

The institution, from its humble beginning, continuously grows and produces pupils and students whose talents and skills bring laurels to themselves and to this institution. A great number of AICS alumni have thus far earned success in varied fields of endeavor. AICS will forever be the light that beckons the youth into its fold and will keep on its missions as an Academic Institution committed to Service.
