Established on February 13, 1972, it was originally known as the Iloilo Doctors' Hospital School of Nursing and Midwifery.

A year later, the school’s operations were transferred to the newly formed Integrated Educational Corporation Iloilo (IECI), which was approved by the Securities and Exchange Commission (SEC) on February 9, 1973.

The formation of IECI allowed the school to expand its facilities, including the construction of additional buildings and a 1,200-seat college gymnasium, along with a swimming pool.

In 2011, IDC introduced new courses in Psychology and Business Administration, and the Child Learning Center began offering elementary school levels.

Over the years, many IDC graduates have excelled in their respective professional fields, contributing significantly to both public and private sectors.
