Formerly known as Kapt. Eddie T. Reyes Memorial Elementary School-Palar Annex in Cluster IX of Taguig, it is located at Scorpion St. Palar Village, Barangay Pinagsama, Taguig City. It has a total land area of 2,100 square meters.

This school was established in 2004 when the Taguig Administration met with various stakeholders such as Philip Morris Corporation and Philippine Business for Social Progress (PBSP) for school building donation at the Philippine Army Light Armor Regiment (PALAR) Village due to the public clamor for a school in the community of informal settlers.

The only vacant portion left in the area then was a site formerly used as a target range by Army soldiers. The remains of which was a thick slab of concrete wall still visible at the rear portion of the school’s stage. This former target range was under the stewardship of the Rotary Community Corps (RCC), a voluntary organization who asked the Bases Conversion Development Authority (BCDA), which has title over the area, to use it as a garden under its LOVE Ecology Projects sponsored by the Rotary Club of Makati Greenbelt since 2001. The golden coconut tree, the only living remnant of the RCC’s LOVE Ecology Garden project, could still be seen at the school premises.

The RCC lobbied AHHAI-FOMCRES not to oppose the building projects donation of PHILIP Morris and PBSP. Then, the construction of a two-classroom building was ensured near the barangay plaza. It turned out to be an annex of KERIS (once known as KERMES-Main), which catered 291 excess Grade I-Grade VI pupils of the aforementioned school. The school’s first administrator in 2004 was Mrs. Marina G. Evangelista, followed by Dr. Teodoro Melegrito as Officer-In-Charge.

In mid-2004, the Fort Bonifacio Group of Companies under the auspices of the City and PBSP built a two-storey, six-classroom building. The Kinder-Grade V pupils utilized this building while the PHILIP Morris building was occupied by the Grade VI.

In October 2006, Rep. Eulogio “Amang” Magsaysay of AVE Party List donated a multipurpose building which was used as the principal’s office, library, and computer room.

During the administration of the late Mrs. Heddy B. Teneza, enrollment reached 500 pupils, making it a complete elementary school at that time. The school had 8 classrooms: 2 from PHILIP Morris and 6 from the Fort Bonifacio Group of Companies.

In 2011, Dr. Francia A. Patron took over the school administration. The construction of a three-storey, nine-classroom DepEd building led to the removal of the AVE building to solve classroom shortages due to rapid enrollment growth.

Currently, Palar Integrated School is under the supervision of Dr. Magdalena G. Centeno. I Love Taguig constructed a four-storey, twelve-classroom building to accommodate the growing number of students.

The school continuously demonstrates remarkable improvements in facilities, projects, and activities to deliver quality education. Now on its 13th year, Palar Integrated School has reached 2,900 pupils from Kinder to Grade VIII during the 2016-2017 school year, with 70 teachers and a Principal II at its helm.
