Yes, Many Provider organizations have more than one DYCD contract. Each contract (defined by its contract ID) will be organized into a separate cohort. You will be able to run reports on a cohort that is associated with a single DYCD contract ID.
Note: The Hats & Ladders system receives contract ID data from the YEPS system. Given the Hats & Ladders system automatically receives data from the YEPS system, no provider organization will need to enter/know group codes. Group codes are just used on the backend of our platform.
