Each student needs to register separately. If an agency wants to use one credit card to pay for all of the students at one time, upload a letter/PO that lists the names of all of the students who will be paid for with the credit card. The letter should state that a credit card will be used to pay for those students listed in the letter/PO and should also mention who the agency point of contact is for the credit card, to include that person’s contact information.
