This event is impossible without support!
NEW and REVISED categories are HERE!!!
LACSEF has revised its categories for the 2026 fair, adding new areas such as Applied Computational Science, Biomedical Engineering, and Robotics. Please click here for the complete list.
LACSEF is excited to announce that we are now offering a free training workshop open to all teachers, site coordinators, and parents!
This self-paced course is designed to equip you with essential information, practical preparation, and actionable steps to effectively support students participating in the regional competition.
The full course takes approximately eight hours to complete when followed diligently. Built-in self-checks and evaluations appear throughout the modules to help reinforce your learning. At the end of the course, participants will take a final assessment; a score of 80% or higher is required to pass, after which a certificate of completion will be issued. Participants will retain access to all materials through the end of May.
The training is organized into clear, structured sections. Please review each section carefully. Throughout your involvement with the Science and Engineering Fair, you are welcome to contact LACSEF team members or the course facilitator, Anthony Quan at quan_anthony@lacoe.edu with any questions.
Course Sections:
Part 1: Site Coordinators and the Role of the Fair
Part 2: Pre-Approvals and the SRC
Part 3: Getting Started with Students
Part 4: Competition Day
LACSEF is offering virtual office hours!
