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.

  • Part 2: Pre-Approvals and the SRC

  • Part 3: Get­ting Start­ed with Students

  • Part 4: Com­pe­ti­tion Day
