IUSD Students Take Top Honors at Orange County Science and Engineering Fair, Advance to State

OCSEF 2025

Nearly 30 students from IUSD secured top honors at the recent Orange County Science and Engineering Fair (OCSEF) across diverse categories.

These students will now head to the California Science and Engineering Fair and ThermoFisher Junior Innovators Challenge, scheduled to take place on April 12-13. This prestigious event will bring together some of the brightest young minds from across the state, providing our students a platform to showcase their innovative research and compete at the highest level.

The competition, divided into Junior and Senior levels, commenced last September, inviting students to submit their STEM projects across 20 category topics. This year, over 800 students from across Orange County participated. The winners in each category received a medal, certificate and cash prize.

Sebastian Alexis and Nathan Kang from Northwood High School and Annika Chatterjee from University High School were also nominated to attend the International Science & Engineering Fair (ISEF) in May. Several IUSD students also won Special Award prizes, some of which also included cash rewards, from various STEM organizations. 

"IUSD is proud of our student participants and their remarkable projects," stated Director of STEM Bob Curley. "Their accomplishments speak volumes about the commitment of our students and the guidance of our teachers, who continually inspire a profound appreciation for scientific inquiry.

Congratulations to all who participated and those who are moving on to the State competition!
