Scholarships are currently available via the Foundation for Science and Technology (FCT); check for calls here, normally once a year.
Usually FCT Scholarships entail prior acceptance to the course, as a formal University letter of acceptance is normally required; however, any changes to regulations and further enquiries should be clarified and addressed directly to FCT.

Occasionally, ID+ and/or specific projects offer additional scholarships within the scope of ongoing research; calls will be announced via social media and mailing lists.
