All Early Decision applicants must read and sign the Early Decision Agreement found in the Common Application. Complete the Early Decision Agreement form with your secondary school guidance counselor. 

Grinnell's Early Decision program is binding. If you are accepted under either of our Early Decision options, you must withdraw applications submitted to other colleges. You may not apply to more than one institution as an Early Decision candidate.

While the binding nature of Early Decision means you will not be able to compare financial aid offers among colleges, at Grinnell the aid package you receive under Early Decision is the same you would receive if admitted under the regular decision plan. So there is no reason to hold off if Grinnell is your clear first choice.
