Since 1950, The Los Angeles County Science and Engineering Fair (LACSEF) has conducted an annual science and engineering fair for 6th — 12th grade students from public, charter, private, parochial, and homeschool schools throughout Los Angeles County. We celebrate students’ STEM achievements, assist Los Angeles County schools in implementing more hands-on inquiry based science and engineering instruction, and develop the next generation of scientists, engineers, mathematicians, and innovators. We are totally dependent on donations from industry, businesses, and friends like you to make the science fair possible.

You can easily and safely donate to the Los Angeles County Science & Engineering Fair and help to fund the largest and longest running regional science fair in the western United States, dedicated to fostering STEM careers and science education.

We have been honored with one of the first Top-Rated Awards of 2024 from GreatNonprofits! We appreciate all of your contributions!
