All Grinnell students make a $100 damage deposit that is separate from the advance tuition deposit and is included in the first semester billing. The deposit serves as a breakage deposit in the science laboratories and also is applied to any fines or outstanding bills at the end of each semester. Before registration each fall semester, students must restore the damage deposit to $100 (if necessary). Any unused portion of the deposit will be returned upon graduation or withdrawal from Grinnell. The deposits are not returned while students are on official college leave.
