Will Cloud Service Providers (CSPs) that apply for an ET prioritization also be applying for a FedRAMP authorization at the same time?

Yes, CSPs will likely be applying for FedRAMP authorization and ET Prioritization at the same time. They are not linked in the ET Prioritization Framework because the authorization paths are changing as a result of the anticipated finalized OMB Memo. The exact details of how the processes will be integrated and rolled out will be made clearer in future blogs and documentation after the new paths are released.
