ACSI Student Leadership & Learning partners with Grand Canyon University to provide an International Christian STEM Competition (ICSC) for students in grades 6-12. This event is designed to showcase the incredible potential of students from Christian schools in the fields of Science, Technology, Engineering, and Mathematics (STEM). With a unique blend of academic rigor and faith-based values, this competition aims to foster creativity, critical thinking, and collaboration while reinforcing the integration of faith and scientific exploration. Summaries of each of the 2026 ICSC challenges are available for preview on our webpage.
New for 2026- On-site Design: A Challenge for Everyone! No separate sign-up needed, Onsite Design is now for all participants! Every student will get to tackle two challenges this year: their chosen challenge and the Onsite Design Challenge!
We will also be offering Venture: Entrepreneurial Innovation Challenge, running simultaneously to ICSC, and we would encourage you to register a team for that competition. Venture is a comprehensive program that allows students in grades 6–12 to build and refine their entrepreneurial skills. This challenge is designed not only to showcase students' pitch talents but also to provide a hands-on, immersive entrepreneurial experience.
You will receive your 2026 ICSC Advisor Information Document within one business day. This document will contain all the information you need to start preparing your students, along with essential deadlines and instructions on how to submit your challenge choices, team names, and student participant names.
