There are two SUBgroups cohorts each fall, to accommodate different start dates for semesters and quarters. One cohort begins in early September and the other begins in early October. Participants can choose whichever timing works best for them. The September cohort tends to be larger, so you should consider signing up for that cohort if you have more specific requests about the makeup of your group, even if you have a later start date.
Registration for our September 2026 cohort is now open! Here is the registration form. The registration window for the September cohort is August 17-28. You will need to read the SUBgroups Handbook before the start of the program. If you’d like an email reminder when registration opens for the October cohort, submit your email address here.
Our registration form has four sections: Basics, Participant Agreement, Demographic Info, and Group Preferences. For Demographic info, please use the timezone you will be in for the duration of SUBgroups, not the timezone you are in as of filling out the form.
After submitting your registration form, you will receive an email from SUBgroups within 24 hours to confirm email contact. Your registration is not complete until you reply to this email. If you do not receive this email, first check your spam folder, and then email us:
