The school continued to grow with the establishment of IJA-Kalibo in 2003. Classes for about 35 pre-school children were held in a rented building across the town plaza of Kalibo, Aklan. In December of the same year, negotiations for the acquisition of a half-hectare property were completed and the new IJA-Kalibo campus was built. The main building which houses classrooms and other academic facilities like the library and laboratories was named Dr. Alberto T. Mallonga Hall in honor of the school’s founding president. The school was granted government recognition in 2006 for complete courses in the Pre-Elementary , Elementary and Secondary levels. In the same year, this campus was certified by FAPE as an ESC participating school and in 2009, it became a member of CEAP. The school has been serving as the testing center of the Ateneo de Manila University for its Ateneo College Entrance Test (ACET) since 2008. Likewise, the University of Santo Tomas (UST) has also established linkages with the school starting 2011 for its college admission test. IJA Kalibo now serves as a testing center in Aklan for the University of Santo Tomas Entrance Test (USTET).
As in the case of the other IJA schools, the IJA Kalibo Family Council (IJAKFC) was immediately organized upon the school’s establishment in 2003. The IJAKFC is actively engaged in activities and programs that benefit the entire IJA community.
In 2011, a new building was constructed in this campus to address its growing population’s needs. This building bears the name of the beloved Directress and Founder of the IJA System of Schools, Mrs. Consolacion F. Mallonga.
