Where your letter of recommendation can be high-level and general, the answers here should provide as much detail and evidence as possible for each prompt, as these questions make up the core of the evaluation rubric. You will also be able to upload additional documents of support (Letters of Recommendation, Essays, News Clipings, etc) later in the form.
A letter of nomination from the nominator is required, but the quality of additional support provided can bolster a nominee's score considerably. Consider getting letters of support from the nominee's current or previous supervisor(s), leaders of community groups with which the nominee volunteers, or peers from the campus or surrounding community. News articles published to your university or department website or local news can also be used as support.
Supporting Documents: Essays, Letters of Support, Newspaper clippings, etc.
