How the Program Works
STEM Sisters is a self-paced, staff-supported program. Girl Scouts complete the quarterly activities at their own pace and share what they've learned and created along the way.
Whether you're completing challenges independently, with your family, or alongside your troop, STEM Sisters allows you to explore STEM in a way that fits your schedule.
Registration Information
STEM Sisters is a year-round program with rolling registration, so you can join at any time during the program year.
After registering, you'll receive a confirmation email that includes the required 2026-2027 STEM Sisters Internet Safety & Photo Release Form. This form must be completed before you can receive an invitation to join the STEM Sisters Rallyhood community.
Rallyhood invitations are typically sent twice each month, around the 1st and 15th.
