There are states that have concurrent clinical requirements and not all states accept EC's academic curriculum.
Excellsior College new york nursing graduates have had same issue recently. see state board licensure requirements here
These are states having concerns over concurrent therory and practicum, so i would look at other 37 states to obtain license: Alabama Arizona California Georgia
Maryland North Dakota Oklahoma Vermont Virginia
Even once licensed in one state......another state may refuse you licensure by endorsement. However I know a Paramedic that went to EC and is an excellent RN.......they were an excellent paramedic as well.
