Judging at OSSEF

Judges represent unique and exciting STEM workforce pathways for Oklahoma youth. Judges provide invaluable encouragement and a connection to what's possible for STEM-interested young people.

Judging at the Oklahoma State Science and Engineering Fair provides excellent opportunities for personal, corporate or organized-based service and outreach to the statewide community of STEM-focused youth. Organizations are encouraged to promote OSSEF as a service opportunity for their employees.

The 2027 Oklahoma State Science and Engineering Fair will be held on the OSU Stillwater campus, Friday April 2, 2027. Students qualify for OSSEF via competition in one of Oklahoma's eight Regional Fairs. OSSEF is the state-level competition.
