The mission of the Los Angeles County Science and Engineering Fair (LACSEF) is to increase literacy and foster diversity, equity, and inclusion in Science, Technology,  Engineering, and Math (STEM) education and related fields for Middle and High School students throughout Los Angeles County. LACSEF seeks to promote hands-on learning experiences, inquiry-based science, and design-thinking engineering that extends beyond the traditional classroom setting so that students develop the critical thinking, problem solving, and resilience skills necessary to prepare for future careers in STEM-related fields.

Since 1950, The Los Angeles County Science and Engineering Fair has been an organization dedicated to increasing literacy and fostering diversity, equity, and inclusion in Science, Technology, Engineering, and Math (STEM) education and related fields for over 900.000 Middle and High School students throughout Los Angeles County. It is estimated that over 3,000 students are impacted by the event, as students compete in school science fairs that feed into our fair. For many students, this is the only extracurricular access they have to STEM related activities.
