OCSEF, also known as the Orange County Science & Engineering Fair, is an annual event aimed at inspiring the youth of Orange County to explore the world of science and engineering. This non-profit organization provides equal opportunities for 6th-12th grade students from both public and private schools in the county. The mission of OCSEF is to foster scientific literacy, critical thinking, and STEM education for all students in Orange County.

By supporting teachers through workshops and mentoring, OCSEF enhances the science curriculum and promotes local school science and engineering fairs. Since 1955, the dedicated educators, scientists, and engineers involved with OCSEF have been committed to guiding and motivating students to engage in project-based learning across all STEM fields. The fair provides students with a platform to showcase their projects and have discussions with expert judges.

The outstanding exhibits at OCSEF have the opportunity to advance to the California State Science Fair, Broadcom MASTERS competition, and Intel International Science and Engineering Fair. In addition to the fair, OCSEF offers various programs and resources such as mentorship, STEM evenings, and pathways to support students' scientific journey. To further contribute to the scientific community, OCSEF conducts workshops and outreach activities for teachers and students.

Whether you are a student, teacher, or supporter of science education, OCSEF welcomes you to explore their website for valuable information and encourages you to get involved in their mission
