Eulogio Rodriguez Integrated School has a rich history that dates back to its humble beginnings as Hagdang Bato Barrio School, established in honor of former Secretary of Agriculture and Commerce, Hon. Eulogio “Amang” Rodriguez Sr. The school was originally a two-room building, constructed in 1939 through a Mandaluyong Council resolution that appropriated P8,000.00 for the project. The building was intended for Grade III and IV classes, whose students were sent to Mandaluyong Elementary School for the higher grades.

In 1953, an annex building was added, thanks to a National Fund supplemented by the municipal office. The municipal government also funded the construction of a shop building. As the school continued to grow and evolve, its name changed to Eulogio Rodriguez Elementary School in 1956 after the organization of the intermediate grades. Mr. Andres Evangelista became the school's first principal after it gained independence in 1947, followed by a long line of dedicated principals who helped shape its development and improvement.

Today, Eulogio Rodriguez Integrated School is more than just an elementary and intermediate school. It is now a fully integrated school, offering secondary education (Junior High School and Senior High School) to its students as well. This expansion is due to the newly constructed building funded and blessed by the National government. The school changed its name to Eulogio Rodriguez Integrated School (ERIS) in 2009 to reflect this change.

Throughout its history, ERIS has built strong ties with LGUs, NGOs, and the SPTA, working together to create a child-friendly environment that supports the academic and personal growth of its students. This vision is fully supported by the school's administrators, teachers, and non-teaching staff, all of whom are committed to providing the best possible education to the students of ERIS. As the school moves forward, it will continue to build on its rich history and strive to provide a quality education to all its students.
