International Masterclasses (IMC) is a program to engage high school students in authentic one-day particle physics analysis experiences at universities and laboratories worldwide. The program is run under the aegis of the International Particle Physics Outreach Group (IPPOG). The COVID pandemic created challenges for IMC in trying to reach the participants and excite them about cutting-edge science. Meeting those challenges not only addressed immediate issues but also expanded the capacity of IMC to deliver its program in the future. The authors will share what they have learned and prospects for the future.
