The graduates of 2009 are the first to wear the Isidran Academic Regalia during their graduation last March 27, 2009.  The Dean of Student Affairs, Prof. Amber A. Paguray, and a committee took the initiative to lead the research and finally design  the Isidran Academic Regalia.  The project was endorsed by the Academic Council chaired by the VPAA and was approved by the President.

The color of the academic gown is powder blue.  Through the years blue has become the identity of San Isidro College as it is reflected on the school uniforms, banner, logo, etc.  The color of the hoods are as follows:  white for AB-English, copper for AB-Economics, dark blue for AB-Philosophy, scarlet for AB-Theology, light blue for Education, drab for BSBA, BSA and BSOA, salmon pink for Health Courses.  The Stole of Gratitude is white embroidered with the school logo. To give distinction to the honor graduates, they wear the gold Honor Cord aside from the Stole of Gratitude..

The Isidran Academic Regalia helps define the identity of San Isidro College along with its Vision-Mission and Core Values.
