Each cohort should have a registration drop-down choice in our forms that allows you to register for the cohort. If the option is missing, check the start dates to make sure that date hasn’t passed. You cannot register for cohorts that have already started. You may register up until the start date of any cohort, as long as you are paying using a direct online payment or registration, purchase orders/invoices require more time to process on our end and will become unavailable 3 or 4 business days before the start date.
