Both. You need to fill out the form, sign it yourself, and have the health prof committee sign it too... Now the committee has a choice to either just fill out the form, which kinda sucks because there isn't a lot of room to write great stuff about you, or they can submit a group letter or each a personal evaluation letter. It just depends on how well your committee does its job. Either way they ask for the form to be sent with the evaluation(s) so they can match it to your file.
