making sense of ester award...for 2019 class

Hi all! Congrats to those accepted to Rice class of 2019. My child has been accepted and we are happy but we are trying to make sense of the award found in Ester. The awards and loans listed on Ester don’t equal the cost of attendance. The school is closed now but perhaps some on this board will know the answer. Can I assume that you subtract the cost of attendance, which is no where to be found on the ester website, from the awards/loans/grants that were given to you on Ester??? If that is correct than in addition to the student loans the difference would have to be made up through addidtional loans???

ie: total awards equal 43k however when you go on Rice site and check cost of attendance it equals 58,283.

Help

Our award sound very similar. Mine totaled out to 46k I think?? I assumed the rest was to be covered my family’s Expected Family Contribution.
