In 1979, a 2-hectare (4.9-acre) lot in Ibayo was acquired and a building was built to facilitate the Industrial Arts and Physical Education classes.
A one-story building was also rented near the plaza, which was used as the school office, canteen and one room, but it was eventually demolished.
For that matter, the school decided to add third, fourth and fifth floors on the original ICA building, which is now the ICA-SHS.
The Immaculate Conception Academy (ICA) is paired as the junior (high school) varsity team of the Emilio Aguinaldo College (EAC).
This team won 5th Best Team and Most Intensive Routine for High School Coed Cheer Division and National Champions for High School Girls Cheer Division during the National Cheerleading Championships held at Ynares Sports Arena on March 5, 2011.
